EAN-13 check

Client

EAN-13 is the common 13-digit consumer barcode worldwide (GTIN-13). Paste digits for mod-10 pass/fail—Toolcore flags 978/979 prefixes as likely book ISBN-13 but still runs GTIN math.

EAN-13 readout

Thirteen digits after cleanup. Mod-10 on full string. Optional hint when prefix matches book ISBN ranges—use dedicated ISBN tools for hyphen layout.

Privacy: every comparison runs locally in your tab. Toolcore performs no GS1 registry lookup, product database match, or price scan—checksum math only.
?

GTIN‑8, UPC‑A (GTIN‑12), EAN‑13, and logistic GTIN‑14 all end with the same ISO/IEC GS1 modulus‑10 weight‑3 algorithm used by the barcode generator when it pads shortened bodies with a check digit. Alternate lengths map to retailer packaging standards (coupon GTIN‑12, carton GTIN‑14, compact GTIN‑8).

Result

Passes modulus‑10 GS1 rule for GTIN-13 (13 digits).

Common use cases

  • Validate EU and global retail barcode columns.
  • Sanity-check ISBN-13 barcodes before book listing import.

Common mistakes to avoid

  • Assuming every EAN-13 is a book ISBN

    978/979 prefixes suggest books—most EAN-13 values are general retail GTINs.

FAQ

Is EAN-13 the same as GTIN-13?
