Amazon & UPC Codes: All the Answers for Amazon Sellers

Leah McHugh covers all the bases for Amazon sellers and UPC codes: where to buy, brands, private labels, bundles and enforcement practices

UPDATE January 2018: This second edition has been fully reviewed and revised.

This post is by Leah McHugh, an ecommerce consultant for For Amazon sellers, having their merchant account suspended means losing time and money trying to get back in business. ecommerceChris shows sellers how to keep their accounts healthy, or, if the worst should happen, how to get their account back from a suspension.

In 2016, Amazon quietly made a change to its Product UPC and GTINs policy (Seller Central login required). It now states:

We verify the authenticity of product UPCs by checking the GS1 database. UPCs that do not match the information provided by GS1 will be considered invalid. We recommend obtaining your UPCs directly from GS1 (and not from other third parties selling UPC licenses) to ensure the appropriate information is reflected in the GS1 database.

What does that mean for sellers?

Well, first you need to understand why Amazon has made this change. Amazon has millions of duplicate listings, where someone has slapped their own barcode onto an existing product in the catalog. Duplicate listings are not good for buyer experience. It confuses customers and dilutes product reviews.

The GS1 policy gives Amazon tighter control over what constitutes a valid listing and reduces the chance of duplicate listings. How? Let’s take a look at how barcodes work.

Barcodes 101

GS1 (Global Standards 1) supply companies with a company prefix, used in GTINs (Global Trade Item Numbers).

UPCs (Universal Product Codes), EANs (European Article Numbers) and JANs (Japanese Article Numbers) are all different kinds of GTINs

GTINs are then turned into Barcodes which are a machine-readable code in the form of numbers and a pattern of parallel lines of varying widths.

The first seven to 11 digits in a barcode, is a unique identifier known as a company prefix. The company prefix identifies the manufacturer or brand owner of the product. This is used to create UPCs for your products.

The ONLY place you can buy legitimate UPCs is through GS1.

The problem with buying UPCs from resellers is that they are selling you someone else’s (hopefully unused) code. The company prefix will not identify you, it will identify the original owner of the UPC. So, if you sell apparel and your code identifies a liquor company, that isn’t going to fly with Amazon anymore.

To be clear, resold barcodes aren’t illegal. I consider UPCs obtained from any source other than GS1 to be grey market. As of 2002, GS1’s license agreement has stated:

The license agreement for our membership prohibits any use of the Company Prefix other than for the use of the owner company, including but not limited to selling, sharing, leasing, sub-dividing, or re-selling the Company Prefix.

Most resellers are selling codes obtained prior to 2002. So you are not breaking the law by using them. However, you are breaking Amazon policy if you use these codes on Amazon.

If you want to see who your UPCs belong to, you can check them on GS1’s Global Electronic Party Information Registry.

So far, Amazon’s enforcement of the UPC policy has been piecemeal. At this time it looks like they are checking the manufacturer field, brand and title to match against GS1. Amazon has started:

  • Automatically checking UPCs against their list of Designated Brands Requiring UPCs when a new listing is being created.
  • Checking existing listings that cite a Designated Brand as the manufacturer, or mentions them in the title.
  • Checking UPCs manually when a seller is under investigation for other reasons, such as misuse of ASIN Variations.

What if your brand name is different from your company name, so it doesn’t match GS1? You need to register with GS1 using your legal company name (or DBA for sole trader). You can then add brand information using GS1’s data hub.

Listing Branded Products That Aren’t Your Brand

If you’re listing a branded product, that is NOT your brand, then you should be using the barcode supplied by the manufacturer.

Amazon policy forbids adding your own UPC to someone else’s product. Your listing and likely your seller account will be shut down. You may even hear from the brand owner’s lawyers. Just don’t do it.

What if the products I’m reselling don’t have a barcode? Contact your supplier. There is no official publicly available list of barcodes, as there is no requirement for registering individual UPCs. Your best source is the manufacturer or brand owner.

If the products do not have GTINs, you can apply for an exemption from Amazon’s UPC requirement. You need a letter from the brand owner confirming that their products do not have a GTIN as well as a link to the product website, or images of the products. You can apply for the exemption here (Seller Central login required).

Listing Your Own Private Label Products

You should ONLY be buying your UPCs from GS1. They will assign you a company prefix, that will identify you as a brand owner. Any company can buy a prefix – you do not need to be incorporated.

May I buy cheap UPCs from eBay or another reseller? No. No, you may not. Go back and read Barcodes 101. If you buy UPCs from a reseller, the codes will identify someone else as the brand owner.

Should you ever decide to sell your products to major retailers, they will only accept GS1 issued UPCs with your company prefix.

May I list my private label products without a UPC? In certain categories, you can apply for an exemption. Amazon will assign your products a Global Catalog Identifier (GCID), which can be used in place of a UPC. You can find the requirement for applying for an exemption here (Seller Central login required).

Listing Bundles

If you’re creating bundles of your own private label products, use a unique GS1 UPC.

NOTE: The UPC must be unique to the bundle – you can not use a UPC from one of the items within the bundle.

For bundles of products from multiple brands, you can apply for a GTIN exemption (see above)

For bundles of products from the same brand, for which you are not the brand owner, you should request a UPC from the brand owner. Note: bundles with products from the same brand are considered as branded products. So, you could also request a UPC exemption with a support letter from the brand owner.

Listings with Incorrect Barcodes

What if I have existing listings with “bad” UPC codes?

I’m guessing that when you started out on Amazon, someone told you that you could buy cheap UPCs from eBay. I still see this advice given regularly by so-called Amazon experts. So, chances are, you have existing listings with not-so-legit UPCs. Now what?

Resellers: is there already a listing with the correct information? List against that and shut down your listing with the incorrect UPC.

If there isn’t a correct listing, you should still shut down or merge your listing, and relist with the correct information.

Private labels: At this point, it looks like Amazon is targeting new listings and sellers listing other brands. However, Amazon’s wording is very clear that this policy applies to all UPCs:

All invalid product UPC listings will be removed and may result in your ASIN creation or selling privileges being temporarily, or permanently, removed.

It is only a matter of time before they begin cleaning up their entire catalog.

I’ve asked around internally and have yet to get an answer on the right way (or Amazon sanctioned way) to handle this. So, as I see it, here are your options:

  1. If you have Brand Registry, then you do not need to list with a UPC. If you set your key attribute as UPC, then you should change your key attribute. Contact Seller Support and request support with Brand Registry. Ask them to change your key attribute to whatever you want to change it to. You should get a response from the Brand Registry team about whether the change is successful or not.
  2. The GTIN field is editable in Seller Central. I know Sellers that have changed this field on existing listings without issue, but I don’t know if that will be the case across the board.
  3. You could create a new, correct listing, and ask Catalog to merge it with the old listing.

Summing Up

Amazon is trying to clean up their catalog. It’s in their interest, and it’s in their customer’s interest, to maintain the integrity of their product listings.

As a seller, you need to make sure your seller account is policy compliant. Weigh the expense of following the rules against the potential lost profits that come with blocked listings and account suspension.

You decide whether it’s worth it.

  1. Great post Leah. Am I correct in assuming that one UPC must have only one listing on Amazon? If yes, is there any suggestion for listing products with fitment data such as printer ink, laptop batteries etc.?

    The issue here is that the better customer experience is to put the fitment data into the title and list one UPC multiple times with different titles e.g “HP Pavillion dv7-1000 battery”, “HP Pavillion dv7-2000 battery” etc.

    With the new UPC policy could we create multiple listings with different titles but the same UPC?

    When there

  2. We have thousands of UPC’s purchased from a third party. We use them to create our own bundles of mixed branded products. When we check the UPC’s for ownership information, the GS1 system responds that there is no record found for owner information (GS1 Japan). Since the results do not find any conflicting ownership information, I’m wondering if those bundles will be safe? We are also updating all of those bundles with our company name for the manufacturer and brand fields, and have removed brand names from the titles and created more generic titles.

    1. Without seeing the actual codes, I can only make an educated guess.

      If the company prefix does not come up in GEPIR ( GS1’s Company Database), then my guess is that they are not legitimate GTINs or they have expired. Either way, this would make them invalid.

      I would suggest contacting GS1 for further information.

      1. Hi Leah,

        You are correct.
        That is the key to using legitimate and valid UPC’s or EAN’s.
        A valid barcode number will have a record in GS1’s database.
        As I have stated in a previous post here, I am a barcode reseller, having been in business now for 11 years.
        My customers have not had any problems listing on Amazon using barcodes purchased from me, because I provide them with GS1 compliant,
        valid UPC barcode numbers.
        As I stated before what my customers have found is that Amazon is checking for the validity of the barcode number, not a “name match” in GS1’s database.

      2. Mark,

        GS1 will not register the UPCs you buy from Robert. Companies, like Roberts, operate in an area which GS1 does not approve. I disagree with Robert’s comments since Amazon is now using GS1 US’s Data Hub to match the Company Prefix to the brand. Resellers use words like compliant and valid but they really are not the best source for information.

      1. Regardless of what some of the reseller have said, you really need to get your own Company Prefix directly from GS1 US. If tomorrow Amazon makes another change , you would be silly to risk getting delisted.

  3. The big problem in the catagory of toys and toy manufactures is that the manufacturers use the same UPC code on many related items. An example would be in diecast cars where a manufactures list the same code for every color or for the same car that is stock and one that is custom. They also sometimes offer the same item with different UPC codes depending on the packaging or special promotion they have offered. The variations can differ greatly and using the manufactures UPC code on Amazon makes it difficult for a buyer to find what they are seaching for. I can understand Amazons thinking because their catalog is a mess. In the toy and toy collector catagory eBay is much easier to shop.

  4. I have seen nothing of this policy in the US. I cannot imagine it will fly very well with manufacturers or sellers in the US. Many manufacturers use recycled numbers – their own or others they have bought. The UPCs are unique to them but no longer match the GTIN database. It also would not be beneficial for consumers as it eliminates lots of bundled buying choices and eliminates a huge part of Amazon’s catalog. It will be interesting to see what happens.

  5. Can you explain this in more detail?

    “The least safe option is to bundle items of different brands, listing the bundle under your own private label, and your own GS1 issued UPC. This is the current loophole which some sellers are taking advantage of to create their own unique listings. I can see this practice coming under scrutiny as more and more sellers attempt to exploit it.”

    Why do you think that using different brands in a bundle is an issue or an exploit? For example, a S’More’s bundle. Marshmallows, Chocolate, and Graham Crackers. All 3 from different manufacturers. Amazon doesn’t even adhere to MAP…in fact they seem directly opposed to it as it’s not in the best interest for a buyer.

    Your article has some good information, however, this is not a policy that has been posted on Seller Central recently. Normally when there’s a new policy or feature (like the new repricer), it will show up on the Seller Central home page. I don’t believe this is a new policy, just one that’s being enforced. Amazon has 45 million books alone. “Fixing” their catalog will likely take years.

    1. I agree that a bundle like the one your described provides value to the consumer.
      The reason I think it will become an issue is because we are already seeing sellers exploit the bundle policy to create duplicate listings and to get around the UPC requirements for Designated Brands Requiring UPCs. For example, a branded item that has been put in a “special” box and then is listed under the sellers PL.

      1. Ah, I see what you mean I think. So a PL seller has a registered brand, but begins using their UPC codes for bundles, thus making them their own branded product even though it’s really just a pack of smores.

        One thing that seems monopolistic to me is that unused UPC’s can’t be sold to a third party and then registered with GS1. I suppose it would be an administrative nightmare. Still, they’re the only ones that can sell new UPC’s, thus artificially inflating the price beyond their real value.

  6. Hi Leah
    I started out with private label products last year on Amazon. I bought UPC codes from as that was what was recommended to me at the time. I registered my brand name with Amazon and have UPC as the key attribute.
    I have built up a lot of reviews on some of the products and it would be a shame to lose them all and start again, especially when newer competitors in the same categories are catching up with me review wise. But I know it would be worse to have my account shut down.
    You mentioned that key attribute could be changed. I never understood what the other options were… I don’t have part numbers printed on the packages or no manufacturer number, catalogue numbers etc. Could it be any name or number?
    Do you know if I have to have an official company registered in the USA to be able to get barcodes from GS1? I’m in Europe but only selling on at the moment.
    I’m happy to only sell on amazon and not in stores but for future products would only use GS1… but for now, to keep things moving, I want to try save my listings and reviews, and have UPC exemption.
    Thanks for the article and your help

    1. Thanks Norm,

      As you are already enrolled in Brand Registry, you could you the GCID which is a 16 character ID Amazon assigned to your listings. You can find it in your inventory report. You would need to contact the catalog and ask them to change your key attribute. The GCID can be used across countries.

      If you have no intention of selling in stores, then I wouldn’t bother using a UPC if you are able to use the exemption. But, if you choose to purchase from GS1, they have offices in most European countries, so you are able to register in the country where your business is located.

  7. Hi Leah,

    Is it not possible to purchase new UPC codes from GS1 and then just change the barcodes round on your existing listings rather than deleting the whole listing.

    Or will a change in barcode mean you loose all your data for that listing?


    1. Hi Abz,
      Unfortunately, it is not possible to change the UPC on an existing listing on Amazon. To change the UPC you need to create a new listing with the correct information and delete the incorrect listing.
      Alternatively, if it is your Private Label you can apply for Brand Registry and use something other than UPC as your key attribute. That would remove the incorrect UPC’s from your existing listings.

  8. UPDATE: Speedy Barcode has added the following verbiage to their site, addressing Amazon’s policy change:

    “Amazon has recently updated their company policy and put a barcode ownership verification process in place. At this time, Amazon is using GS1’s GEPIR database as the sole means of verification. We have contacted Amazon to let them know that the database they are using is not current and does not reflect correct ownership information for all of the barcode numbers GS1 has listed, but as per an email from them, they have no plans to change their process. At this time, you have no choice but to obtain barcodes from GS1 if you want to list your products on Amazon.”

    1. We dealt with Speedy Barcode in the past and they have no clue what they are talking about. Go straight to GS1 US.

    2. Absolutely not correct!
      As I have stated here before
      Amazon is not, I repeat not doing name checks in GS1’s database
      What they are checking for is the validity of the code itself
      If it is a valid code, the barcode number will have a record in the database, if it is fake, there will be no record
      Validity, not name match!

      1. Robert,

        Do you work for Amazon? There isn’t an official barcode database. GS1 maintains a searchable database of Company Prefixes which can be used to validate If a prefix is uniquely assigned to a brand. I do not work for Amazon nor GS1 but our other retail trading partners follow this process.

  9. Hi Leah,

    When I’m setting up my company prefix on the GS1 website, do I put my importing LLC as the company name? Or do I put my brand name (very different from my LLC)? I read through their FAQ but couldn’t find the answer. Would prefer LLC, but trying to select the option that won’t get me flagged/suspended by Amazon later.

    Thanks for a great article by the way.

    1. Thank you, Billy.

      You must register with GS1 using your legal company name. And your should register a DBA for your brand name.

      If it came to your listings being blocked because your DBA didn’t match your company name in GS1, you could very easily provide your DBA paperwork and GS1 certificate, proving your codes are legit.

      1. Our entity has a GS1 certificate that we use to assign UPCs to a variety f Brands that we sell… per note above, can I ‘Register MULTIPLE DBAs’ to cover this Amazon requirement? Thks, Ron

  10. What if your company is a sole proprietorship and has a DBA for the company name and the company name is different from the Brand? Should the UPC codes be registered under the company DBA, the sole proprietor’s name, or other?

  11. 1) We sell our private label product on amazon and we have brand registry for our brand. We have selected Manufacturer part number as unique identifier for all our listings which is different than UPC, However we also provided UPC code along with Manufacturer part #. But these UPC codes were not bought on GS1 website so GS1 does not have our company info for these UPC code.

    Now amazon changed the policy on us suddenly. Even though I have not received any complain from amazon about any of our listing, Is this policy update will affect our listing which is under our brand registry with unique manufacturer part # along with so called non complain UPC code.

    1. Hi Rina,

      This is a developing story. In the last few weeks we have seen Amazon merging listings with different UPCs. We have also seen Amazon changing Product IDs to ASIN in Seller Central.

      Brand Registry with a key attribute other than UPC is the best protection you can do on your own, other than closing and relisting the items with the correct information.

      Alternatively, you could contact catalog and ask them to change the listing information. I do not recommend changing the product IDs yourself.

  12. Hi,

    I sell a lot of vintage items (Corningware, Pyrex and dinnerware) that do not have UPCs. Many of the original manufacturers are no longer in business. The UPC requirement on Amazon has significantly impacted my small business. Most people are surprised when I tell them that selling vintage and collectible items on Amazon was more profitable for me than selling on eBay or other sites. It looks like I won’t be able to do business on Amazon for much longer. If I understand it correctly, I can’t use my own UPC on a 1970s Pyrex casserole, because I’m not the manufacturer. I still see many listings of vintage and collectible items, so I’m wondering how those sellers are bypassing the UPC requirements.

  13. Hi Leah,

    Great article, I’ve read it several times actually.
    I wanted to react in the comments and build on Rina’s comment as well. I’m in the same situation, that is that I’ve switched the key identifier from UPC to manufacture part number with brand registry; however the UPC, non registered under my PL name, is still shown in the listing. Is that still OK?

      1. Leah, another question I had was this:
        If I’m brand registered with manufacture part number as a key identifier, what should I use as barcodes when sending products to amazon’s warehouses? Should it be the manufacture part number (which in my case is sku number)

  14. Hi there! I have only heard of this just now. I have about 200 products listed with Amazon. I was going to purchase 200 new UPC’s but learned I have to go through GS1. 200 UPC’s will cost me $2,500 plus an annual fee of $500. I think this is HIGHWAY ROBBERY and a monopoly, which includes price gouging. If I have to change all my existing UPCs, then that’s another 200 UPCs and another $3000.

    I’m sure GS1 is laughing all the way to the bank. I’m furious because I am a small business owner and this is a horrific hardship and extremely bureaucratic.

    I’m just venting. And I have no choice, as I see it. If anyone has more insight, but I’ve read through this blog, and see no hope.

    I’m glad there is this forum to discuss this. Thank you for listening to me.

    1. I agree that the GS1 cost is prohibitive for so many small or home businesses. It’s greed at its worst. The worst thing is that the huge GS1 prices have to be paid every year! Amazon can’t possibly care about these businesses surviving. And the crazy thing is that many home businesses have no intention of selling in retail stores; they are online only.

  15. This is great. I’d like your opinion on another scenario, converters.

    Say a tape is converted to the same size by two companies, each creating their own unique UPC. Should these ASINs be merged by Amazon? Is there another way Amazon is positioning this?

  16. Hi Leah,

    I am a reseller of some OEM ink and toner printer cartridges which will be easy to obtain the UPC the actual brand manufacture but I also sell way compatible and remanufactured ink and toner cartridges and when an order comes in, I choose from about 10 different drop shipping suppliers, which would be crazy to obtain all of those manufactures UPC because they probably get them from different manufactures in different countries themselves….

    If its not correct to use the actual brand manufactures UPC on compatible and remanufactures generic cartridges because they were made by another manufacture who may be unknown vs using the original brand manufacture UPC on the compatible cartridges since the generic product is a duplicate of the OEM.

    Do we just use the OEM UPC on the generic cartridges or can we be exempt from adding UPC to amazon ?


  17. The identification by brand is normally the relevant component to how UPCs should be assigned. The OEM branded items should carry the OEM assigned UPCs. I would NOT recommend assigning those OEM UPCs to the generic cartridges. If you make all 10 suppliers as separately available options, you would need to have all 10 provide their UPCs. However, if you are selling those remanufactured cartridges under your “generic brand”, you would need to assign the UPCs yourself from your own GS1 Company Prefix. T

  18. Hello All,

    Full disclosure my name is Robert Simms, I am the owner of Legal Barcodes. My company has been in business providing GS1 compliant UPC/EAN barcodes to the small business community for 10+ years.

    I find the misinformation about Amazons UPC policy to be stunning.

    It is unfortunate that the lack of understanding of what Amazons new policy actually means and says, has possibly cost the small business community hundreds of dollars.

    I have clients who purchase barcodes daily to use to list their products on Amazon.
    They are not having any issues at all.
    It would not be in my best interest to sell them a barcode that they could not use on Amazon, or in the majority of retail stores around the world.
    What Amazon is doing is what I have noted below, here and on our website.
    ***A Note On Amazon’s “New” Barcode Policy***

    There has been a lot of information/ misinformation regarding Amazon’s “new” acceptance policy regarding UPC/EAN barcodes purchased to list products on their website.

    Based on our customer feedback and information from Amazon this is what we know.

    1)Amazon is now checking GS1’s database to ensure that the barcodes you submit are valid barcode numbers

    Valid meaning that when Amazon checks your barcode number it has a record in GS1’s database.

    A “fake” or randomly made up barcode number will not have a record in GS1’s database.

    What Amazon is not doing based on our customer feedback is rejecting your barcode numbers if the name in GS1’s database does not match your name or company name.

    2)What Amazon has also been doing is cracking down on vendors who attempt to list “Branded” products

    For example:

    Say you have a pair of Nike socks that you purchased and want to sell them on Amazon When you go to list the Nike socks on Amazon and use a barcode number that does not match the original barcode as issued by Nike, Amazon is rejecting the listing.

    These are the examples of the “new” Amazon barcode policy.

    Based on what we know to be true, we still offer our guarantee that the barcodes you purchase will be accepted by Amazon, as long as the product itself meets Amazon’s standards.

  19. Hi Leah,

    Great article– I’m still looking for some answers, though. I hope you can help me with my question. I have been trying to get someone at Seller Support to answer, but I’m not getting any responses.

    I have GTIN Exemption and have added products to my inventory (they are not live yet) and have had SKUs & ASINs generated by Amazon assigned to my products. My question to you is, do I need a GS1 barcode (separate from the numbers Amazon assigned), or do I just need to print the ASIN? What about the SKU -does that # go anywhere? Also, is SKU the same as FNSKU and do I need one of those? The code requirements are so overwhelming!

    Additionally, the products I’ve listed will be sold individually as well as part of a bundle. My question is, is the ASIN/SKU or any other # assigned to the individual products relevant in the bundle?

    Thanks so much!

    1. If you have an exemption you don’t need a GS1 UPC. You would use the FNSKU to label the product. The SKU identifies the product and the FNSKU identifies both the product and you as the seller. It is assigned by Amazon.

      The bundled products need their own unique identifier. The ASIN/ SKU of the individual products is not relevant to the bundle.

  20. Hi
    All great info but my head is spinning a bit. I have just created a seller account as i want to move online. But i sell mostly unique and all handmade items from around the world sourced in markets and villages from Morocco to Thailand. What’s the best way to get codes or should i apply for exemption? Many thanks.

    1. Hi Martin, Firstly, as a traveler that loves Thailand and Morocco, that’s awesome!
      You could look into Amazon handmade, which doesn’t require UPCs, or you could create your own brand to put the items under (if they aren’t already branded) and apply for brand registry.

  21. Thanks for the update to this article. I have designed my own products that are sold under my company name. So it appears I should get original UPC codes from the approved source, GS-1. However, from the only price list I could find on there, it appears qty 100 is the lowest I can purchase. I only need around 20. Do you know if they do custom, smaller amounts for small businesses? It does not make economic sense to have to buy more than I will ever need. Help!

  22. That is a great suggestion. If you called GS US They would never provide this type of information. Most likely they would tell you your only option would be to buy a prefix to allow hundred assignments. However their site does allow you to get multiple company prefixes.

  23. Leah,
    i am trying to list my national brand using the brand’s UPCs but someone way back in 2012 has used a few of our UPCs on some other product.
    What do you recommend I do regarding this issue?
    I don’t want to have to sticker my own product, esp. since I’m not planning on others selling it and will be the only seller on Amazon and i have a substantial volume of the products.
    I’ve listed the products using GTIN exception now but that still doesn’t solve my issue with stickering.

    1. You can open a case with the Catalog department, and show them that the UPC’s belong to you and your product.

      That being said, I recommend anyone using FBA opt out of commingling. Stickering with an FNSKU an added safeguard in case someone starts reselling or counterfeiting your product. The last thing you want is to be blamed for someone else selling inferior product, and with commingled inventory, there is no way for Amazon to identify which inventory comes from which seller.

  24. Hi- I am a reseller on Amazon. One of the manufacturer’s products that I resell – their UPCs are NOT registered with GS1. The products are already listed on Amazon by the manufacturer. Should I create new listings with UPCs registered under my reselling company with GS1?

  25. Hi there,
    I make decals. I don’t have any MPN or UPC for these items. How can I sell on Amazon. Please help.


  26. I sell books. I like to find books in a series and sell the whole series. Now Amazon requires an bundle code. I was given some vague instructions to make a list of products I’d like to sell as a bundle, but I’m not sure how they want it presented. What do you know of this?

  27. thank you for share your valuable information with us.
    Is it not possible to purchase new UPC codes from GS1 and then just change the barcodes round on your existing listings rather than deleting the whole listing.

  28. We have an assigned barcode from GS1 payed big dollars for it. Someone at company called “AquaGuard” has a fraudulent number using our UPC most likely purchase off line real cheep. Amazon never checked the code with GS1 and because they were in the system 1st, our company can’t list our 20 skus. Sort of like this guy (Hi Leah said; he started out with private label products last year on Amazon. bought UPC codes from as that was what was recommended to me at the time. I registered my brand name with Amazon and have UPC as the key attribute.) So, he got cheep UPC code off line, the guy that pay’s Big Dollars from GS1 is basically screwed because someone didn’t want to pay for fee with GS1. My question is: This impostor (AquaGuard), using our barcode assigned to our company on Amazon, prevents us from becoming a vendor with Amazon. I’ve filed multiple complaints with Seller Central and no one every fixes the issue. I’ve supplied our certificate confirmation that we own the UPC but Amazon won’t delete the fraudulent barcode of “AquaGuard”, and Amazon also failed to have their UPC verified with GS1 US, they (Amazon) would of found out the UPC number was already had ownership. Like the guy posting above (Leah) he saved a lot of money going with a cheep provider on line, but has cost our company a nightmare! What can be done to fix this issue???
