ICCID supplier quality audit

Client

ICCID supplier quality audit supports receiving teams sampling serial columns from supplier manifests. Paste random rows plus edge cases—confirm Luhn pass rate before signing acceptance documents.

Receiving dock checklist

Sample paste, record pass/fail, quarantine failures, request supplier correction before ERP receipt posting.

Privacy: digits are evaluated only inside your browser. There is no carrier, GSMA, or SM-DP+ query—format math only. Treat SIM identifiers like any sensitive operational paste.
?

The ITU‑T E.118 layout follows ISO/IEC 7812 for card identifiers: a Major Industry Identifier (telecom ICCIDs usually start with 89), an issuer/country/account block, then a trailing Luhn mod‑10 check digit using the same doubling rule as many payment PAN validators. Printed cards commonly show 18–22 digits; issuers pin one length profile per range.

Result

Passes Luhn mod 10 on the full 19-digit string.

  • MII (first 2): 89
  • Issuer / account core (between MII and check): 3530012345678901
  • Check digit (last): 1

Common use cases

  • Sample 10% of pallet ICCIDs before warehouse put-away.
  • Compare two suppliers' CSV quality during RFP evaluation.
  • Attach Luhn audit notes to non-conformance reports.

Common mistakes to avoid

  • Auditing only the first and last row

    Sample throughout the file—errors cluster in middle batches.

  • Rejecting stock for one Luhn fail without root cause

    Could be export corruption—re-scan physical card.

  • Using audit as legal ownership transfer

    Format check complements—not replaces—contractual acceptance.
