Clear answers regarding IMEI verification, blacklist records and device security

The International Mobile Equipment Identity (IMEI) is a 15-digit globally unique serial number that identifies your mobile phone on cellular networks. No two authentic phones in the world share the same IMEI code.
Simply enter your 15-digit IMEI in our Blacklist Checker. Our system queries global GSMA operator databases in real time to verify that the device is clean and not reported lost or stolen.
Open your phone app and dial *#06#. The 15-digit code will display on the screen instantly. You can also find it under Settings > General > About (iPhone) or Settings > About Phone (Android).
A blacklisted device has been reported stolen, lost, or flagged due to unpaid contractual balances. When placed on the GSMA blacklist, cellular carriers block network registration, rendering calls and mobile data unusable.
Yes! Dual-SIM smartphones have two distinct cellular radios and therefore feature IMEI 1 and IMEI 2. Each IMEI connects independently to carrier networks and can be checked separately.
Completely safe and 100% legal. Our web service does not install any software on your device and only reads publicly verifiable GSMA allocation information and carrier status records.
