Read the guide →Check a device before you buy it or try to unlock it. Identify the device associated with an IMEI, understand carrier and network restrictions, and find the official next steps for your situation.
Enter a 15 digit IMEI to check its format and checksum, then search the first eight digits, called the TAC, in our local device catalog. When the catalog has a match, it can show the manufacturer and model associated with that TAC.
A format and catalog match do not confirm that the full IMEI is genuine, identify the phone’s current carrier, or check blacklist, carrier-lock, Activation Lock, ownership, or unlock eligibility. Those checks require separate authoritative data from the carrier, Apple, or an authorized device-status provider.
Learn what an IMEI can and cannot tell youCarrier unlock, network unlock, and SIM unlock describe a restriction that can prevent a device from using another compatible network. The carrier that applied the restriction decides whether it can be removed.
Our current IMEI check validates the number’s format and searches a community device catalog. It does not determine carrier lock status or unlock eligibility, and we don’t submit unlock requests. We explain how to find the official route for your carrier.

An IMEI or online bypass offer cannot legitimately remove Apple Activation Lock. The available next step depends on whether you own the Apple Account, bought the device used, or have proof of purchase. A carrier lock is separate and follows the carrier’s unlock process.
