Dual slot IMEI validator
ClientDual slot IMEI validator helps when phones expose IMEI1 and IMEI2 for two physical or logical SIM slots. Paste each decimal IMEI separately—or one per line for bulk—without assuming both slots share one modem ID.
Dual slot intake tip
Forms may ask for primary slot only or both. Validate each pasted IMEI independently—Luhn pass on IMEI1 does not imply IMEI2 is correct.
?
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
- Dual slot IMEI validator on imported dual-SIM handset intake.
- Compare IMEI1 vs IMEI2 on activation paperwork.
- Support tickets where only one slot IMEI was validated.
Common mistakes to avoid
Assuming dual-SIM phones share one IMEI
Each radio slot may have its own IMEI—check both if required.
Pasting both IMEIs concatenated
One IMEI per line—15 or 16 digits each after cleanup.
Expecting dual slot check to prove both lines active
Format validation only—not carrier activation state.
