SSCC checksum checker

Client

Warehouse and EDI feeds often paste SSCC values beside consumer GTINs on the same shipment row. This page strips separators and an optional (00) application identifier, then recomputes the GS1 modulus‑10 check digit—pair with GTIN checksum when the label also lists an EAN‑13 or GTIN‑14.

About SSCC checksum

18-digit Serial Shipping Container Code—GS1 modulus‑10 check digit; optional (00) prefix stripped; no registry lookup; browser-only. The interactive transform on this page runs in your browser tab—Toolcore does not need your paste for the core operation described above.

How to use this page

Paste or type in the main workspace, run the primary action from the toolbar, then copy or download the result. Use Load example when the page offers it, or URL prefill (?q= / ?qb=) so agents and tickets open the same input.

Privacy: checksum math runs locally in your tab. Toolcore does not query GS1 or logistics registries—format and modulus‑10 only.
?

Serial Shipping Container Codes are 18 digits: an extension digit, company prefix, serial reference, and GS1 modulus‑10 check digit. Barcodes often prefix (00) as the application identifier—this page strips that when twenty digits remain.

Result

Carton labels often sit beside consumer GTINs—open GTIN checksum when the same pallet row also lists an EAN‑13 or GTIN‑14.

Common use cases

  • Sanity-check an SSCC copied from a WMS export before loading it into a TMS or carrier API payload.
  • Explain why an 18-digit logistics unit fails GS1 mod‑10 while a related GTIN‑14 on the same row still passes.
  • Strip a leading (00) application identifier from a 20-digit scan before comparing against an internal master list.
  • Contrast SSCC extension digit rules with GTIN‑14 packaging levels in mixed retail and logistics spreadsheets.

Common mistakes to avoid

  • Treating a passing check as proof the container or license plate exists

    Checksum validation confirms arithmetic only—not that GS1 assigned the company prefix or that the serial is active in a registry.

  • Applying consumer GTIN length rules to SSCC

    SSCC is always 18 digits after cleanup (extension digit + reference + check)—not GTIN‑8/12/13/14 lengths.

  • Expecting GS1 GEPIR or logistics directory lookup

    Company names and location metadata require licensed GS1 services—this page performs local format math only.

FAQ

Does Toolcore query GS1 or a logistics registry?

No—the check digit and layout rules run entirely in your browser tab.

Why strip a leading 00?

GS1 barcodes often encode application identifier (00) before the 18-digit SSCC; when twenty digits remain after cleanup, this tool removes the prefix.

Is the SSCC check the same as GTIN mod‑10?

Yes—both use the GS1 ISO modulus‑10 weight‑3 algorithm on the body before the trailing check digit.
