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

  • Confirm 14 digit IMEI expectations before trusting inventory or support CSV rows.
  • Paste digits locally—no carrier, GSMA, or stolen-device database lookup.

Common mistakes to avoid

  • Treating format pass as live carrier or blacklist status

    Luhn and TAC hints do not prove activation, warranty, or lost/stolen registry state.

  • Forcing 14-digit strings into the wrong identifier type (IMEI vs IMEISV).
