How this service works
Validate up to 100 GTIN-8, UPC/GTIN-12, GTIN-13, or GTIN-14 identifiers including check digits.
Output
Returns a validation result for each submitted GTIN indicating whether it is structurally valid (correct length and format for GTIN-8/12/13/14) and whether the check digit is correct, along with any error details for invalid identifiers.
Example use cases
Pre-upload catalog GTIN audit
“I have a batch of 50 product GTINs I need to validate before uploading to Google Merchant Center — can you check all of them for valid format and correct check digits? Here's the list: 00614141453395, 9780201379624, 0614141000418...”
E-commerce barcode QA check
“We just received a new supplier's product sheet with UPC codes and EAN-13 barcodes — can you validate these identifiers to make sure none of them have bad check digits before we add them to our store: 012345678905, 4006381333931, 5901234123457?”
Feed error diagnosis
“Our product feed keeps getting rejected and I suspect some GTINs are malformed — can you run a check on these identifiers and tell me which ones are invalid: 614141453395, 00012345678905, 7501031311309, 12345670?”
