IMEI & DEVICE IDENTIFICATION
IMEI Check: Identify Your Device
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.

Is your device locked?
Carrier 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.

Searching for an “iCloud unlock” or “iCloud bypass”?
If you’re searching for how to unlock iCloud, an iCloud unlock online, or an iCloud bypass, first identify the restriction. 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.
INDEPENDENT INFORMATION
We explain the options. Apple and carriers handle account and lock decisions.
iCloudUnlocker is not affiliated with Apple. We do not remove Activation Lock or access Apple accounts. A TAC catalog match is informational only: it does not verify device authenticity, blacklist status, carrier lock, Activation Lock, or unlock eligibility.
