Google Merchant Center Invalid GTIN: What It Means and How to Fix It
Summary
An invalid GTIN error means the barcode number you provided does not pass Google's validation checks. This can happen with typos, wrong product codes, or using GTINs that do not belong to your products.
Quick Answer
Your GTIN (barcode number) failed validation. Verify you are using the correct GTIN for each specific product—typically found on the product barcode or packaging. Do not guess or make up numbers.
What This Issue Means
GTIN (Global Trade Item Number) is a unique identifier for products. Google validates GTINs against official databases. If your GTIN does not match the product, is malformed, or is not registered, your listing will be rejected.
Why It Happens
- •Typo in the GTIN field
- •Using a GTIN that belongs to a different product
- •GTIN is not registered or recognized in Google's database
- •Product does not have a valid GTIN (e.g., custom-made items)
- •GTIN belongs to your supplier, not your product
- •Mismatched GTIN and MPN combination
What to Check First
- Locate the correct GTIN on the actual product packaging or barcode
- Verify the GTIN matches the specific product (not similar items)
- Confirm the product is not custom-made (custom items do not need GTIN)
- Cross-check with your supplier if you are a reseller
- Ensure the MPN and brand are also correct
Evidence to Prepare
- •Photo of the product barcode (EAN, UPC, or ISBN)
- •Product packaging showing the GTIN
- •Supplier invoice with the product's GTIN
- •Screenshot of your feed data showing the GTIN field
Step-by-Step Recovery Path
- 1Find the actual GTIN on the physical product or its packaging
- 2Enter the exact GTIN in your product feed
- 3If the product is custom or a bundle, set gtin to empty and add 'identifier_exists' = 'no'
- 4Resubmit the product feed
- 5If validation still fails, check if the GTIN is registered in Gs1.org
Mistakes to Avoid
- ✕Making up or guessing a GTIN
- ✕Using the supplier's GTIN when you are a reseller and not authorized
- ✕Using the same GTIN for multiple similar products
- ✕Not setting identifier_exists to 'no' for products without valid GTINs
- ✕Not checking if the product is actually a bundle that needs different handling
When to Ask an Expert
Consider reaching out to an expert if:
- •You are unsure whether you are authorized to use a specific GTIN
- •The GTIN appears correct but validation keeps failing
- •You sell custom or hand-made products without standard GTINs
- •You need help with identifier_exists settings for bundles
