Invalid GTIN

Meta couldn't validate the GTIN you supplied — wrong length, bad check digit, or formatted incorrectly.

Same root causes as Google's invalid GTIN — Excel stripping leading zeros, manufacturer codes mistakenly placed in gtin field, or restricted GTIN ranges.

1. Validate every GTIN with a check-digit calculator before submission.
2. Format spreadsheets as Text to preserve leading zeros.
3. Use only GS1-issued GTINs, not Amazon-only ASINs.
4. Resubmit.
