How to validate identifiers

  1. Paste one GTIN per line, preserving leading zeros.
  2. Run the tool to check 8-, 12-, 13- and 14-digit identifiers.
  3. Review invalid results against your original product records and export the findings.

Understand the results

A valid checksum does not confirm that a number belongs to your product, brand or company. Verify product assignment separately and never invent a GTIN to clear a feed error.
