GSMA IMEI validator
ClientGSMA IMEI validator matches searches referencing GSMA numbering—this page validates decimal structure and Luhn locally. It does not query GSMA databases, TAC directories, or blacklist feeds.
GSMA format vs GSMA services
GSMA publishes IMEI layout standards. Live TAC allocation and device registry services are separate commercial systems—not invoked when you paste digits here.
?
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):

Common use cases
- GSMA IMEI validator for training on standard handset IMEI layout.
- Pre-validate IMEI columns citing GSMA specs in RFP responses.
- Distinguish format compliance from live registry lookup in docs.
Common mistakes to avoid
Expecting GSMA validator to return manufacturer certificate
Format math only—no GSMA API integration.
Using GSMA label for CDMA MEID validation
MEID is a different identifier system.
Assuming GSMA pass means GSMA membership device
Luhn pass is syntactic—not brand authentication.
