SSCC Checker User Guide – Validate Logistics Unit Serial Codes with Ease

What is an SSCC?

SSCC (Serial Shipping Container Code) is an 18‑digit GS1 identifier for logistics units (e.g., pallets, containers). It consists of an extension digit (1–9), a GS1 company prefix, a serial reference, and a mod 10 check digit. SSCCs are commonly encoded in GS1‑128 barcodes or RFID tags to support end‑to‑end supply chain tracking.

How to Use This SSCC Checker?

1. Enter the 18‑digit number (non‑digits are automatically stripped).
2. Click “Validate” – the tool checks the extension digit, length, and mod 10 checksum (same algorithm as EAN‑13).
3. View the result instantly.

This SSCC Checker is completely free and ideal for logistics managers, warehouse operators, and EDI specialists.

Frequently Asked Questions

1. Does this SSCC Checker confirm that the logistics unit actually exists?

No – it validates the syntactic correctness of the SSCC. Actual existence must be verified through the issuing party’s system.

2. What does the extension digit (first digit) indicate?

It is assigned by the company to differentiate logistics levels; valid values are 1–9 (0 is not used for SSCC).

3. How is the checksum calculated?

Same as EAN‑13: sum the first 17 digits with odd positions weighted by 3 and even positions by 1, then take the 10’s complement of the modulo‑10 sum.
