GTIN-14 check

Client

GTIN-14 identifies case and pallet levels with a packaging indicator digit. Paste fourteen digits for mod-10 validation—no warehouse inventory lookup.

GTIN-14 structure hint

Fourteen digits: packaging indicator, item reference, company prefix field, check digit. Toolcore validates mod-10; detailed indicator semantics are in GS1 general specifications.

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 case GTINs on ASN and EDI 856 files.
  • Catch check-digit errors before pallet label print runs.

Common mistakes to avoid

  • Using consumer UPC where GTIN-14 case code is required

    Inner pack vs case level use different GTIN assignments—length must match role.
