ICCID data migration validator

Client

ICCID data migration validator helps cutover weekends when SIM assets move between systems. Validate legacy ICCID columns for Luhn and length before transform scripts—catch bad rows before production load.

Cutover preflight

Extract ICCID column, paste sample and full batch, fix failures in source, re-export, then run ETL.

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

  • Preflight SIM inventory extract from retiring ERP.
  • Compare transformed ICCID column against source checksum.
  • Document migration sign-off with sample Luhn reports.

Common mistakes to avoid

  • Migrating without normalizing spaces and dashes

    Strip separators first—this page does that on paste.

  • Padding short strings to force length

    Fix source data—do not invent digits.

  • Treating migration validator as dedupe tool

    Run separate duplicate detection in your ETL.
