"Codes do not match the products you are trying to list"

This error usually relates to the Brand/Product Identity field, not the barcode itself.

What it means

Amazon's system checks the Brand attribute in your listing. If it doesn't match expectations or requires Brand Registry, the listing is blocked.

Try this first
  1. Check your "Brand" field. It must match your actual product brand exactly
  2. For private-label products, enter "Generic" or "Unbranded" instead of your company name
  3. Verify the UPC isn't already assigned to a different product (search it on Amazon)
  4. Try listing in a related category with fewer restrictions
  5. Consider applying for GTIN Exemption if appropriate

I purchased this UPC from Bar Codes Talk, an authorized barcode reseller with 28+ years in business. The UPC is legitimate and unused. I'm receiving error 8572 but believe this is a Brand/Product Identity field issue, not a problem with the barcode itself. Please advise on the correct Brand field entry for my product.

I am receiving error code 8572 when attempting to list my product. Details: • UPC: [YOUR UPC HERE] • Product: [YOUR PRODUCT NAME] • Brand field entry: [WHAT YOU ENTERED] • Category: [CATEGORY] I purchased this UPC from Bar Codes Talk, an authorized reseller operating for 28+ years. The barcode is legitimate and has not been used previously. I believe this error relates to the Brand/Product Identity field requirements rather than the UPC itself. I have tried entering "Generic" and "Unbranded" as alternatives. Please advise: 1. What should I enter in the Brand field for this product? 2. Is this category restricted to Brand Registry members only? 3. Would a GTIN exemption be appropriate for my situation? Thank you for your assistance.

GS1 / Certificate

"Not recognized by GS1" or certificate request

Amazon is referencing GS1 database lookups. We can provide documentation if needed.

Important: Amazon often references GS1 lookups that show the original company prefix owner, which can appear as a mismatch. If Amazon requests documentation, we can provide supporting certificates for your purchase. Send us the screenshot and your UPC/GTIN.
What it means

GS1 manages barcode prefixes. When barcodes are legitimately resold, the original prefix owner information remains in GS1's database. This is normal and doesn't affect validity.

Try this first
  1. Don't panic. Your barcode is legitimate
  2. Check your Brand field and try "Generic" or "Unbranded"
  3. Contact us for documentation if Amazon requests it
  4. Use the message templates below to respond to Amazon
Note: We cannot edit GS1 ownership records or list you as the GS1 prefix owner. GS1 ownership is controlled exclusively by GS1. However, resold barcodes are legitimate for commercial use.

Message to Amazon Seller Support
I purchased this UPC from Bar Codes Talk, a legitimate barcode reseller operating for 28+ years. The GS1 database shows the original prefix owner, which is normal for resold barcodes. I can provide a certificate of purchase from my supplier if needed. Please advise on next steps.

I understand you're seeing a GS1 lookup that shows a different company name for my UPC prefix. This is expected and does not indicate a problem with the barcode. Explanation: • I purchased this UPC from Bar Codes Talk, an established barcode reseller operating since 1996 • When barcodes are legitimately resold, the original GS1 prefix owner information remains in the GS1 database • This is standard practice in the barcode industry and does not affect the validity or usability of the code • The barcode has been assigned exclusively to me and has not been used elsewhere I can provide: • Certificate of purchase from Bar Codes Talk • Proof of my exclusive rights to this UPC Please let me know what documentation you need and I will provide it promptly. Thank you.

Need documentation?

Send us your UPC and a screenshot of Amazon's request. We'll provide a certificate.

Ownership

"Registered to another company" or name mismatch

GS1 shows the original prefix owner. This is expected for legitimately resold barcodes.

What it means

When UPC prefixes are originally issued by GS1, they're assigned to a specific company. When those barcodes are legitimately resold, the original ownership information remains in GS1's database.

Try this first
  1. Understand this is normal. The GS1 lookup shows the original prefix holder
  2. Check your Brand field for conflicts with existing registered brands
  3. Contact Amazon Seller Support with the explanation below
  4. Request documentation from us if Amazon requires proof

I'm writing regarding the company name mismatch message for my UPC. Background: • UPC: [YOUR UPC HERE] • I purchased this barcode from Bar Codes Talk, a legitimate barcode reseller operating since 1996 • The company shown in GS1 records is the original prefix owner, not my company This is expected behavior: • When UPCs are resold, the original GS1 prefix owner remains in the database • This does not affect the validity or legitimacy of the barcode • Barcode resale is a standard industry practice I can provide: • Certificate of purchase confirming my exclusive rights to this UPC • Documentation from Bar Codes Talk verifying the transaction Please advise on what specific documentation you need. Thank you.

Brand Registry

"You may not create ASINs for this brand"

This is an Amazon policy restriction, not a barcode issue.

What it means

Amazon Brand Registry gives brand owners control over their listings. If you're trying to list under a registered brand or your brand name triggers protection systems, you'll be blocked.

Try this first
  1. If you own the brand: verify your Brand Registry is active and you're logged into the correct account
  2. For unbranded products: use "Generic" or "Unbranded" in the Brand field
  3. If reselling branded products: search for the existing ASIN and list against that instead
  4. Consider applying for GTIN Exemption for legitimate unbranded products
Brand Registry issues are Amazon account/policy matters. Bar Codes Talk cannot resolve Brand Registry restrictions. You'll need to work with Amazon directly.

Error 8541 / 8542

"SKU conflicts with the Amazon catalog"

Your listing data doesn't match what's already in Amazon's catalog for this UPC.

What it means

The UPC is already associated with a product in Amazon's catalog, and your listing details (title, brand, etc.) don't match. Amazon won't let you create a conflicting listing.

Try this first
  1. Search the UPC on Amazon to see what product is currently assigned to it
  2. If it's your product from a previous listing, match that existing data
  3. If it's a different product, contact us to verify your UPC assignment
  4. If selling the same product, list against the existing ASIN instead of creating new
  5. Try using a different UPC that isn't in Amazon's system

Validation

"Product ID is invalid"

Amazon says your UPC/EAN doesn't pass validation. Usually a simple fix.

Try this first
  1. Copy the UPC directly from your purchase confirmation to avoid typos
  2. Verify the Product ID type: 12 digits = UPC, 13 digits = EAN
  3. Use our free barcode verifier to check the code is mathematically valid
  4. Make sure you're including any leading zeros (UPCs should be exactly 12 digits)

Error 8556

"Product is ineligible"

Amazon says your product cannot be sold at this time. This is usually a category or policy issue.

Try this first
  1. Check if your category requires approval (some categories like health, beauty, automotive require it)
  2. Search the UPC on Amazon to see if it's associated with a restricted or recalled product
  3. Apply for category approval in Seller Central under "Add a Product"
  4. Contact Amazon Seller Support for clarification on why this specific product is blocked
