When to use mod10 calculator

Use after barcode misreads, Excel scientific notation damage, or when a supplier file drops the final check digit. Re-scan the physical card when possible.

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

  • Replace spreadsheet Luhn macros on locked-down corporate laptops.
  • Explain mod-10 pass/fail to non-telecom stakeholders.
  • Debug transposed digits before carrier portal entry.

Common mistakes to avoid

  • Including spaces in manual Luhn math

    Strip separators first—the tool normalizes before mod-10.

  • Expecting mod10 pass to mean active SIM

    Format validation only—not provisioning status.

  • Using calculator output on IMSI strings

    Validate ICCID columns only—IMSI uses different rules.
