ICCID call center validation

Client

ICCID call center validation gives agents a fast format check when customers read serials over the phone. Confirm Luhn before opening carrier tickets—reduce rework from simple digit transpositions.

Agent script hook

After customer reads digits, agent pastes, confirms Luhn, then collects IMSI and MSISDN as separate fields for carrier CRM.

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

  • Validate read-back ICCIDs during live calls.
  • Train BPO scripts with one bookmarkable validator URL.
  • Pre-check serials before warm-transfer to tier-2.

Common mistakes to avoid

  • Reading IMSI when customer says SIM number

    Ask specifically for ICCID or SIM serial on the card.

  • Telling customer Luhn fail means canceled line

    Often a read-back error—have them re-read the card.

  • Using speakerphone for 20-digit read-back

    Request photo upload through secure channel when possible.
