Troubleshooting

UPC to GS1 Change

Amazon checks every product ID against the GS1 database, and listings with unmatched UPCs can be taken down without warning. We move your ASINs to valid GS1 barcodes while keeping reviews, rank, and inventory intact.

  • UPCs bought from resellers
  • GS1 database mismatches
  • Brand Registry or A+ Content denied over barcodes
  • Listings flagged for invalid product IDs

Most updates take 5 to 45 days, depending on Brand Registry status and Amazon's review times.

Every day offline costs sales.

Send us the notice from Seller Central and a specialist will review it and outline next steps.

Don't let it sit

What's at risk if this waits

Automated enforcement

Amazon's systems flag and suppress listings with non-compliant barcodes automatically.

Suppression without warning

Listings can disappear overnight when a product ID doesn't match GS1 records.

Brand tools denied

Brand Registry, A+ Content, and Brand Story updates can be rejected.

Lost reviews and rank

Forced catalog merges can detach reviews and sales history.

Sudden revenue drops

One suppressed best-seller can stall sales and cash flow.

Older listings audited too

Long-running listings are being checked, not just new ones.

Our process

Keep selling while we make the change

We update your existing ASINs rather than creating new ones, so in most cases your listing stays live, inventory isn't affected, and reviews stay attached.

  • Existing ASINs updated, not replaced
  • Listings stay live in most cases
  • FBA inventory unaffected
  • Reviews and rank preserved
Getting barcodes

Buy authentic barcodes the right way

Barcodes bought from resellers are the most common cause of mismatches. We'll show you how to license GTINs directly from GS1 in your brand's name, so the problem doesn't come back.

  • Barcodes licensed to your brand
  • Right number of GTINs for your catalog
  • Assigned correctly to each variation
