IMEI serial number validator
ClientIMEI serial number validator clarifies the six-digit serial portion within the 15-digit IMEI—not the alphanumeric device serial on the back panel. Paste IMEI for Luhn plus serial segment readout.
IMEI serial vs device serial
IMEI serial is embedded in the 15-digit modem identifier. Product serial numbers on labels are manufacturer asset tags—do not interchange them on carrier forms.
?
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
- Compare serial segments across two IMEIs from the same TAC batch.
- Train QA on difference between IMEI serial and product SN.
- Document serial segment in RMA tickets after Luhn pass.
Common mistakes to avoid
Validating product serial number as IMEI
Device SN uses different format—paste decimal IMEI from About.
Expecting serial segment to prove manufacturing date
Segment order is OEM-specific—not a public date decoder here.
Using serial validator for SIM ICCID
ICCID validates with SIM tools—different length and Luhn context.
FAQ
Where is the serial in IMEI?
Typically digits 9–14 of a valid 15-digit IMEI after the 8-digit TAC.
Same as iPhone serial number?
No—Apple SN is separate from the modem IMEI serial segment.
Does validator check uniqueness?
No—shows segment digits only; no global uniqueness database.
