IMEI Luhn check

Client

IMEI Luhn check targets mod-10 searches specifically. Paste a 15-digit IMEI—the same Luhn engine as the main checker, labeled for checksum-focused bookmarks and SEO.

Luhn on IMEI vs PAN

Both use mod-10, but IMEI carries TAC and serial segments after Luhn passes. Use payment card tools when the sample is explicitly a PAN.

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

Common mistakes to avoid

  • Running Luhn on MEID hex strings

    MEID validation uses different rules—confirm identifier type.

  • Expecting Luhn pass to mean active service

    Checksum only—not HLR or billing state.

  • Ignoring 14-digit bodies missing the check digit

    Synthesize or paste full 15 digits for authoritative Luhn result.
