Use of IMEI

Blocking the lost /stolen device-

Increased usage of mobile devices has resulted in a remarkable increase of stealing, and losing of the device. Under these conditions, the owner can use the IMEI number for preventing further usage of the device. The owner needs to call the network service provider and inform them about the situation. The service provider can block the phone on their network and can also notify the other network providers.

Identifying the model and origin of the device-

IMEI number comprises of 15 digits out of which the initial 8 digits (also known as TAC) give a clue about the origin and model of the device. Manufacturer can be identified with the next 6 digits.

Tracking the device-

The owners can register with the Mobile Tracker service providers using their mobile numbers. Whenever the device is used with a different Sim Card, a notification is sent to the registered mobile number of the owner.

Advantages of IMEI number

Restricting the instances of mobile theft-

IMEI number is now a universally accepted measure. To restrict the usage of a stolen device and hence control the instances of theft, IMEI numbers have played a prominent role.

Swift stoppage of services-

In countries like the UK, the operator can quickly transmit the message with IMEI number to the Central Equipment Identity Register, which subsequently floats it to all other network providers. Devices are blacklisted within 48 hours on all the networks.

IMEI (International Mobile Station Equipment Identity) number identifies legitimate devices using the GSM network. This 15 digit (14 digits plus a check digit in the last) number is a prominent measure to trim down the instances of using a stolen/lost mobile phone. You can locate the IMEI number of your cell phone either on the box, or printed inside the battery compartment. The IMEI number can be used by the owner of the mobile device to blacklist the phone. For this, the owner should call the network service provider and instruct them to stop any further services of the phone.

IMEI number is strictly related to the mobile device and has no relation with the user. The Telecom authorities of many countries have introduced stringent measures to make it mandatory for the manufacturers to produce devices bearing a valid IMEI number. Though law-breakers have originated many ways to change the IMEI number, they rarely opt for this due to rigorous regulatory compliances.

The digits comprising the IMEI number represent the origin, model, and the serial number of the mobile device. The initial eight digits define the model and origin, and are collectively termed as Type Allocation Code. The following six digits define the manufacturer and the last digit (check digit) is calculated using Luhn algorithm. The check digit is the function of the digits prior to it.
