Stolen phone IMEI format check

Client

Searches mentioning stolen phone IMEI often confuse format validation with blacklist lookup. This page is honest: we check Luhn, length, and TAC split only—we do not query stolen-device, CEIR, or carrier lost/stolen registries.

What we do not do

No CEIR query, no carrier blacklist API, no GSMA stolen-device database. Format validation helps catch typos—it does not clear or flag theft status.

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

  • Verify a pasted IMEI is structurally valid before filing a police report.
  • Train buyers to reject obvious typo IMEIs on classified listings.
  • Support scripts that separate format QA from carrier blacklist steps.

Common mistakes to avoid

  • Assuming format pass means the phone is not stolen

    Stolen status requires carrier or authority registry lookup—not available here.

  • Paying third-party sites that imply live stolen DB without disclosure

    Ask whether the service queries CEIR or carrier APIs before uploading IMEIs.

  • Skipping carrier blacklist check after format pass

    Run carrier/OEM tools when theft risk matters.
