The IMEI is a 15-digit number that is used to identify a mobile device on a cellular network. It is usually printed on the device's back or bottom, and can also be found by dialing *#06# on the phone. The IMEI is used by network operators to track and manage mobile devices on their networks.

There is no legitimate use case for it. If your phone is blocked because you lost it and it was recovered, contact your carrier to have it removed from the blacklist legally. If the phone is defective, recycle it.
