Your IMEI (International Mobile Equipment Identity) is a number, usually unique, to identify 3GPP (i.e., GSM, UMTS and LTE) and iDEN mobile phones, as well as some satellite phones. Today we will explain what the IMEI is and how to check the number on your mobile.
The word IMEI means International Mobile Equipment Identity and is a unique identifier that each mobile phone has. This means that the IMEI number of your mobile does not have any other phone in the world, and when your device connects to a network it automatically sends this identifier.
The IMEI is a unique identifier of each mobile phone and it is one of code that you will need at times if you have taken it to the technical service or if you had to call your operator to block it because they have stolen it or you have lost it.
The IMEI is a kind of unique identity number for each mobile device, with which you can identify it without error worldwide. Knowing this number will allow you to block your device in case of theft, for which you will only have to notify the operator of the number. It will also allow you to unlock your phone in order to use it with any operator regardless of your brand or model.
The IMEI of your mobile phone has 15 digits and it has no relation with your operator, although it does include references to the manufacturer of the device and the country in which it was manufactured. The code consists of four parts that we explain below:
TAC or Type Allocation Code: Composed by the first 6 digits. Of these, the first two indicate the RBI, which is the organization in charge of regulating the telephone sold, and therefore the country where it was manufactured.
FAC or Final Assembly Code: Composed of the following two digits, which indicate the manufacturer of the equipment.
Serial number: These are the following six digits, and indicate the serial number of the telephone (SNR). Verification Code: It is the last digit of the IMEI, and it is a number that verifies that the IMEI is correct.
The easiest way – the IMEI is usually found printed inside the battery compartment of the phone.
The IMEI number can also be displayed on-screen on most phones by entering *#06# on the dial pad.
Some phones need to press the dial key after entering *#06#, as shown in the pictures.
For iOS phones, do not need to press the dial key.
Sometimes the IMEI number is displayed alongside other system information in the smartphone settings menu.
Method 4: Find IMEI number on package
If you look carefully on the packaging or box, you can sometimes find the IMEI located on it.
The IMEI number is used by a GSM network to identify valid devices and can therefore be used for stopping a stolen phone from accessing that network.
For example, if a mobile phone is stolen, the owner can call his or her network provider and instruct them to "blacklist" the phone using its IMEI number. This renders the phone useless on that network and (sometimes) other networks too, whether or not the phone's SIM has been changed for another.
The IMEI is used purely for identifying the device and has no permanent or semi-permanent relation to the subscriber.
Instead, the subscriber is identified by transmission of an IMSI number, which is stored on a SIM card that can (in theory) be transferred to any handset. However, many network and security features are enabled by knowing the current device being used by a subscriber.
So if you lost cell phone you can tell the police what the IMEI number is.
