ICCID enterprise inventory

Client

ICCID enterprise inventory workflows track SIM assets alongside laptops and phones. Before CMDB import, run Luhn on serial columns so bad rows fail early—this page helps ITAM teams without exposing digits to third-party lookup services.

CMDB import guardrail

Map ICCID column, paste sample rows here, fix failing serials at source, then import. Document that format validation is separate from carrier assignment checks.

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

  • Pre-flight ICCID columns exported from procurement spreadsheets.
  • Audit stale SIM records before annual inventory reconciliation.
  • Pair with IMEI check when asset tags combine handset and SIM paperwork.

Common mistakes to avoid

  • Storing ICCID in plain-text tickets without need

    Treat serials as sensitive operational data even when Luhn passes.

  • Assuming inventory Luhn replaces carrier reconciliation

    Billing and assignment status still live in operator systems.

  • Importing duplicate ICCIDs because checksum passed

    Use batch paste and dedupe in your CMDB—this page flags format only.

FAQ

Is enterprise ICCID validation different?

Same E.118 Luhn rules—enterprise context is volume and CMDB hygiene.

Can MDM teams use this page?

Yes—validate enrollment CSV ICCID columns before upload.

Does Toolcore store enterprise inventory pastes?

No—browser-local evaluation only.
