What is an IMEI Number?

When people buy a new smartphone they usually get so involved in the features and applications that they overlook an important part of their phone – the International Mobile Equipment Identity, IMEI for short. It is a special number assigned to your phone and acts as a unique identifier. You will never find two phones with the same IMEI. This number comes to the rescue when the most dreaded thing happens to us: our phone is lost or stolen. The IMEI is an extremely useful tool for tracking a lost or stolen phone. Depending on which phone you use, there are different ways of locating and identifying your IMEI number. It can also help to identify a device’s model and serial number.

How many digits does an IMEI number have?

An IMEI has 14 digits with an additional 15th digit for verifying the entire number. At times you might also come across a 16-digit variation which usually gives information on the phone’s software version as well. This 16-digit IMEI number is known as the IMEISV. If you have a dual SIM phone, you’ll see two IMEI numbers, one for each slot. These numbers are hardcoded into the phone and are almost impossible to change them without damaging the device itself.

The IMEI follows the AA-BBBBBBB-CCCCCC-D format. The A and B digits which form the Type Allocation Code (TAC) help in identifying the manufacturer and model of the device. The C digits indicate the device’s unique serial number and the D digit ensures that the IMEI meets the appropriate guidelines.

When a mobile network carrier finds out that a certain device has been stolen they can blacklist that IMEI code and block it out of that network. However, there is also a downside to this IMEI affair, if a hacker wants they could possibly track your location through your IMEI.
