Validate IMEI numbers using Luhn algorithm
Validate and check IMEI numbers for mobile devices with our free IMEI Checker. Verify if an IMEI number is valid using the Luhn algorithm, identify the device manufacturer and model through the TAC (Type Allocation Code), and check the format compliance. Important when buying used phones or verifying device authenticity.

View the validation result, manufacturer info, and TAC details.
Use the information to verify the device before purchasing.
Dial *#06# on your phone to display the IMEI. You can also find it in Settings > About Phone, on the SIM tray, or on the original box. iPhones show it in Settings > General > About.
This tool validates the IMEI format and identifies the device type. To check if a phone is reported stolen or blacklisted, you need to use official databases like GSMA's IMEI Database or contact your carrier.
The TAC (Type Allocation Code) is the first 8 digits of an IMEI. It identifies the device manufacturer and model. The remaining digits are a unique serial number and a check digit.
