EAN / UPC checker
Check that EAN-13, UPC-A, EAN-8 and GTIN-14 barcodes have a valid check digit, add a missing one, and convert UPC to EAN. Paste one or hundreds. Runs in your browser.
Numbers
When you open the CSV in a spreadsheet, set the number columns to Text, or long barcodes show as 5.01E+12.
A valid check digit only means the number is well formed. It does not prove the number was issued to you or your brand — marketplaces check that against GS1's records (GS1's own "Verified by GS1" lookup).
