IMEI validator

Client

IMEI validator matches searches for a strict gate before data entry—length guards, digit cleanup, Luhn pass/fail, and TAC breakdown. No carrier or GSMA live lookup; honest format validation only.

Validator vs live lookup

A validator confirms the string is structurally plausible. Carrier portals and OEM tools answer service questions—run those after format pass when needed.

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

  • Validate IMEI columns in MDM or insurance intake CSVs.
  • Gate reseller listings before marketplace upload.
  • Support desk paste-and-verify during activation troubleshooting.

Common mistakes to avoid

  • Using validator output as warranty proof

    Warranty eligibility is OEM/carrier policy—not Luhn math.

  • Validating IMEISV with 15-digit IMEI rules only

    Switch mental model for 16-digit software version fields.

  • Skipping batch mode on multi-line manifests

    Paste one IMEI per line before merging into ERP.
