IMEI Number and its Application

IMEI number is short for International Mobile Equipment Identification number‚ is a series of 15 digits number used to identify the key elements of the phone.

This IMEI number is also used for identification in phone tracing methods and to trace other activities.

IMEI number is usually printed on the phone behind the battery compartment so that it May be found when necessary.

The information that this number is able to store on the phone is amazing. IMEI is unique to each phone and also each IMEI number can explain the origin‚ the model‚ and the serial number of the mobile phone.

This can come in handy if the phone is stolen or if the phone needs to be used as evidence for any legal action.

The original purpose of this number was to block the stolen phone by the operator.

The phone owner could call the network provider and have the phone blocked so that it could not be used with any provider.

This purpose has been expanded to cover phone identification for legal processes.

One can locate the IMEI number on the phone which is located or printed behind or under the battery compartment. Else one can also find the IMEI number by just key in *#06# on your GSM mobile phone and it will display its IMEI number in most phones. Note it down safely.

For phones that have been refurbished‚ one should check to see if the number the phone gives verses the engraved number are the same and should contact your provider if not.

If the IMEI numbers between the phone and the engraving do not match‚ one should call their provider and ensure that it is not going to cause problems later for them.

Because the IMEI is the identification number of the phone and is often used to deter phone theft‚ it is illegal in many places to own the equipment without IMEI or to perform the act of physically changing the IMEI on a phone.

To guard against the purposeful changing of the numbers and the incorrect entry of an IMEI number‚ the phone companies have created a check number that can be derived from the numbers in the IMEI.

This number helps by making it impossible for an individual to change the numbers.

IMEI number can help in tracking or blocking your mobile phone if it is lost. When a phone is switched on‚ the IMEI number is transmitted and checked against a database in the network’s EIR (Equipment Identity Register).

The EIR has three categories namely the white lists‚ grey lists and black lists. The operator can block a handset by putting it in black list.

Also by using Global Positioning System an operator can track the handset user also. But the use of these lists and technologies is at the operator’s discretion.

Generally operators provide these services in case of special investigations only.
