GTIN vs SSCC

Client

GTIN vs SSCC compares product trade item numbers with logistics unit identifiers. SSCC is 18 digits for ship units; GTIN tops out at 14 for item hierarchy—use separate validators.

Identifier comparison

GTIN: 8, 12, 13, or 14 digits, mod-10. SSCC: 18 digits, extension digit, mod-10. Both use GS1 checksum rules but different lengths and business meaning.

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

  • Clarify ASN columns mixing case GTIN and pallet SSCC.
  • Train warehouse staff on two GS1 identifier families.

Common mistakes to avoid

  • Pasting SSCC into GTIN validation

    18-digit SSCC fails GTIN length guards—use the SSCC checker instead.

FAQ

Is SSCC a GTIN?

No—SSCC identifies logistics units; GTIN identifies trade items at defined packaging levels.
