SIM ICCID check

Client

SIM ICCID check is the same workflow as ICCID check with wording aimed at warehouse and retail teams. Paste the printed serial, read Luhn pass/fail, export nothing to our servers.

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

  • Match SIM ICCID on card against portal activation screens.
  • Batch-check shipment files before MDM or ERP import.

Common mistakes to avoid

  • Checking IMSI when the label says ICCID

    SIM cards may print multiple numbers—confirm the ICCID row.
