ICCID retail activation prep

Client

ICCID retail activation prep reduces failed activations at counters and kiosks. Scan or type serial, paste here for Luhn, then enter the carrier POS—catch fat-finger errors before the portal timeout.

Counter workflow

Scan SIM, paste, Luhn pass, then POS. On fail, re-scan card—use suggested check digit if body matches print.

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

  • Prepaid kit activation at franchise retail.
  • Kiosk self-serve flows with manual fallback entry.
  • Train seasonal staff on serial validation before peak traffic.

Common mistakes to avoid

  • Activating before Luhn check on manual entry

    Portal errors waste customer time—validate first.

  • Using SKU barcode as ICCID

    Product SKU is not the SIM serial—scan SIM barcode.

  • Assuming prep activates the line

    No network effects—format check only.
