ICCID port-in check

Client

Port-in rejections often trace to mistyped SIM serials on intake forms. Paste the ICCID from the new carrier SIM before submitting port-in paperwork—catch length and Luhn errors early.

Port-in intake tip

Photograph the SIM barcode when possible, paste here, then copy validated digits into the port-in form—reduces transposition errors on long serials.

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

  • Retail port-in counter validation before POS submission.
  • MVNO onboarding CSV cleanup.
  • Compare port-in ICCID with SIM photo OCR output.

Common mistakes to avoid

  • Confusing port-in account PIN with ICCID

    ICCID is the SIM serial—different field on forms.

  • Using old SIM ICCID on port-in to new carrier

    Validate the new carrier SIM that will receive the ported number.

  • Expecting port-in eligibility from Luhn pass

    Format check only—not porting rules or balance holds.
