ICCID validator

Client

ICCID validator searches want the same workflow as ICCID check: normalize digits, enforce length bounds, run Luhn. This page names that intent explicitly for bookmarking and support macros.

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

  • Validate ICCID columns before ERP or logistics upload.
  • Explain validator pass/fail to non-telecom stakeholders.

Common mistakes to avoid

  • Using validator output as carrier entitlement proof

    Valid checksum ≠ assigned or financed line.

FAQ

What does an ICCID validator check?

Length, digit-only payload, Luhn mod-10, and MII prefix readout.

Is this a GSMA database validator?

No—public checksum math only.
