Rules & checks

Strips non-numeric characters before validation.

Runs checksum math client-side; nothing is stored or sent.

When to use it

  • Validate product barcodes before uploading to catalogs or marketplaces
  • Check supplier spreadsheets for bad codes
  • QA barcode inputs in forms or internal tools

Tips

  • Keep only digits; remove spaces or hyphens
  • Confirm correct length for your channel (UPC vs EAN)

Examples

Valid UPC (GTIN-12)

  • 036000291452 -> valid

Invalid GTIN

  • 12345678 -> invalid checksum

FAQs

Do you scan barcodes?
No. Paste or type codes; we validate the digits and checksum.
