GTIN-8 check

Client

GTIN-8 (EAN-8) suits small packaging where a full EAN-13 will not fit. Paste eight digits for local mod-10 validation—no product catalog lookup.

GTIN-8 validation

Exactly eight digits after cleanup. Rightmost digit is mod-10 check. Toolcore labels the result as GTIN-8 on pass.

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 compact cosmetic or confectionery barcodes.
  • Catch transposed digits on tiny label OCR.

Common mistakes to avoid

  • Padding GTIN-8 to 13 digits without understanding symbology

    GTIN-8 is a distinct length—do not arbitrary zero-fill before checksum.

FAQ

When is GTIN-8 used?
