How To Handle Missing Gtin In Gmc

The Direct Answer

For wholesale cylinder SKUs without manufacturer GTIN, declare identifier_exists=false in the Google Merchant Center feed. Don’t invent GTINs — that’s a policy violation and a buyer-trust risk.

The Slightly Longer Explanation

Wholesale cylinder SKUs often don’t carry consumer-grade GTINs because they’re sold by the pallet through wholesale channels rather than scanned at retail.

Google Merchant Center accepts identifier_exists=false on the feed line. The product still indexes; it just isn’t matched against the GTIN-keyed product graph.

Pair this with a clear brand + MPN field so the listing remains identifiable. Invented GTINs trigger feed suspensions and damage trust signal.

Buyer Checklist

Before you act on the answer above, run through this:

  • Set identifier_exists=false for SKUs without manufacturer GTIN
  • Provide a clear brand + MPN combination instead
  • Never invent GTINs — policy violation plus trust risk
  • Confirm GMC feed validates before submission
