Verify ICCID number

Client

Verify ICCID number requests usually mean checksum validation before retyping into portals—not live entitlement lookup. Paste below for Luhn and MII breakdown.

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

  • Verify ICCID numbers in CSV columns before bulk upload.
  • Confirm OCR scans before printing shipping labels.

Common mistakes to avoid

  • Treating verify as carrier activation

    Passing Luhn does not mean the profile is provisioned.
