ICCID M2M format validator

Client

ICCID M2M format validator aligns with fleet, telematics, and industrial connectivity searches. Paste M2M SIM serials for local Luhn—no carrier HLR, billing, or GSMA directory lookup.

M2M intake workflow

Receiving → sample paste here for Luhn → quarantine fails → proceed to platform provisioning. Format pass is step one—not substitute for carrier confirmation.

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

  • ICCID M2M format validator before fleet provisioning CSV upload.
  • Validate telematics SIM ranges from logistics partners.
  • QA embedded modem SIM serials on manufacturing lines.

Common mistakes to avoid

  • Expecting M2M validator to activate fleet lines

    Format math only—activation is carrier or MVNO portal work.

  • Rejecting valid M2M rows because MII differs from 89

    89 is usual telecom prefix—lab data may differ; read MII hints.

  • Mixing M2M ICCID with device EID on eUICC modules

    EID is hex chip ID—ICCID is decimal profile serial.
