IMEI mod 10 check

Client

IMEI mod 10 check matches technical searches for Luhn checksum on IMEI strings. Paste 15-digit IMEI or 14-digit body—the same mod-10 engine as imei-luhn-check with mod-10 keyword phrasing.

Mod-10 in telecom intake

Many portals silently reject IMEI that fail Luhn. Run mod-10 locally before bulk upload to reduce overnight job failures.

Privacy: digits are parsed only in your browser—no carrier or GSMA lookup, no upload. Treat device identifiers like any sensitive paste on shared machines.
?

A 15-digit IMEI is commonly described as eight-digit TAC + six-digit serial + Luhn check digit; the trailing digit should satisfy ISO/IEC 7812 mod 10 on the full string—same arithmetic as debit/credit PAN checks. A 16-digit IMEISVappends two software version digits instead of exposing the standalone check position; carriers may still relate it to IMEI numbering but this page stops at segmentation and does not certify assignment.

Result

Passes Luhn mod 10 on the 15-digit string.

  • TAC (8): 35693803
  • Serial (6): 564380
  • Check (1): 9

Common use cases

  • IMEI mod 10 check when integrating with billing systems using Luhn gates.
  • Engineering verification against ISO/IEC 7812-style mod-10 implementations.
  • Explain checksum failures to non-telecom finance stakeholders.

Common mistakes to avoid

  • Applying mod 10 to hex MEID strings

    MEID uses different validation—confirm identifier family.

  • Expecting mod 10 to validate ICCID

    ICCID has its own Luhn context—use ICCID tools for SIM serial.

  • Ignoring mod 10 fail on 14-digit paste

    Add synthesized check digit or paste full 15 digits.
