IMEI
IMEI is the acronym for International Mobile Equipment Identity.
International Mobile Equipment Identity
A unique 15-digit numerical identifier assigned to every mobile device with cellular connectivity. It is primarily used to identify devices on a network, ensuring accurate tracking and management of mobile devices. Key functions include:
- Device Identification: The IMEI distinguishes individual devices, even if multiple devices use the same SIM card or number.
- Anti-Theft Measures: Mobile networks use IMEI to block stolen devices, rendering them inoperable on any carrier worldwide by blacklisting the number.
- Device Tracking: Law enforcement agencies can utilize IMEI to locate lost or stolen devices.
- Network Authorization: Cellular providers use IMEI to authenticate devices accessing their networks, ensuring compatibility and security.
Structure of IMEI
An IMEI consists of the following components:
- TAC (Type Allocation Code): The first eight digits identify the device’s make and model.
- Serial Number: The following six digits are unique to each device.
- Check Digit: The final digit validates the IMEI through a Luhn algorithm.
How to Find IMEI
Users can find their IMEI by:
- Dialing
*#06#on the device. - Checking the device’s settings (often under About Phone).
- Looking at the device’s packaging or under the battery (for older models).
While the IMEI helps secure devices, it can also raise privacy concerns if misused. Users should avoid sharing their IMEI unnecessarily to prevent potential cloning or tracking risks.
