GTIN Checksum Audit

ChatGPT plugin

Check product barcode numbers

View in ChatGPT directory

Spot invalid product barcode numbers before you add them to a product list. Paste your GTIN barcode numbers as text. Check their length, digits and final check digit. See which numbers need a closer look, while keeping any leading zeros. This checks the number's maths, not who owns it or whether the product is real.
