The IMEI ( International Mobile Equipment Identification) number is a 15-digit (14 digit plus a check digit) number that's very important in every phone as it shows a lot of important information such as the origin, model and serial number of a phone.
It is usually found printed inside the battery compartment of the phone, but can also be displayed on-screen on most phones by entering *#06# on the dialpad, or alongside other system information in the settings menu on smartphone operating systems.
The IMEI number is used by a GSM network to identify valid devices and therefore can be used for stopping a stolen phone from accessing that network. A lot of times people change their IMEI number and end up bricking their phones or using IMEI thats invalid and hence stop all network activities on their phones.
Before you change an IMEI number you have to understand the structure of IMEI number and know which part to change or tweak so as not to change the variant of the phone. Below is a breakdown/Analysis of an IMEI number:
Sample: (35-676005)-(119201)-(0) from this sample IMEI, the 35 means the IMEI was issued by BABT, 676005 is the Allocation Number for Blackberry Q10 Series and altogether they make the TAC; 119201 is the unique serial No(SRN) that can only be used on a Blackberry Q10 Device at a time while the 0 is the Luhn checksum digit.
Upon having an idea of the structure of an IMEI, it's very easy to generate a new one for tweaking, just follow the step below
To make it easier, you can copy as much as first 10-11 digits and just randomly type any 3 digit more and then click on analyse to get the checksum digit.
Once you see checksum digit correct and IMEI number correct, it means you have successfully created and validated an IMEI number. you can then copy use it for anything intended.
If you have your data connection enabled, you would see the Brand and model of the mobile equipment with the IMEI just below the Analysis/breakdown of the IMEI number.
Below is a video tutorial on this, watch for better understanding

What you should know
Before you change an IMEI number you have to understand the structure of IMEI number and know which part to change or tweak so as not to change the variant of the phone. Below is a breakdown/Analysis of an IMEI number:
- Type Allocation code (TAC) : This is the first eight (8) digits of the IMEI number and the first two digits of the TAC are the Reporting Body Identifier, which identifies the GSMA-approved group that allocated the TAC with the most popular group being the BABT with the code (35) and the remaining 6 digits shows the Mobile equipment type and so the same brand and model of phones would have the same TAC. Prior to 2002, the TAC was six digits long and was followed by a two-digit Final Assembly Code (FAC), which was a manufacturer-specific code indicating the location of the device's construction but ceased to exist after April 1 2004 although it still shows in IMEI Analysers.
- Serial No (SRN): this is the unique serial No used to identify each unit device of a particular kind and brand of mobile equipment and it could be any combination of 6 numbers.
- Luhn Checksum Digit (CD) : The last number of the IMEI is a check digit calculated using the Luhn algorithm, as defined in the IMEI Allocation and Approval Guideline. The purpose of the Check Digit is to help guard against the possibility of incorrect entries to the CEIR and EIR equipment and so it must be properly calculated or validated easily using IMEI analyser.
Sample: (35-676005)-(119201)-(0) from this sample IMEI, the 35 means the IMEI was issued by BABT, 676005 is the Allocation Number for Blackberry Q10 Series and altogether they make the TAC; 119201 is the unique serial No(SRN) that can only be used on a Blackberry Q10 Device at a time while the 0 is the Luhn checksum digit.
How to generate and analyse IMEI for an Android phone
Upon having an idea of the structure of an IMEI, it's very easy to generate a new one for tweaking, just follow the step below
- Download and install IMEI Analyser here.
- Get a sample IMEI for the particular brand and model of mobile equipment you want.
- Copy the TAC ( first 8 digits) and paste into the IMEI Analyser
- Type any Random 6 digits after it, and now you have 8-digit TAC and 6-digit SRN.
- Click on Analyse and the IMEI Analyser would automatically calculate the Luhn checksum digit using the Luhn Algorithm.
To make it easier, you can copy as much as first 10-11 digits and just randomly type any 3 digit more and then click on analyse to get the checksum digit.
Once you see checksum digit correct and IMEI number correct, it means you have successfully created and validated an IMEI number. you can then copy use it for anything intended.
If you have your data connection enabled, you would see the Brand and model of the mobile equipment with the IMEI just below the Analysis/breakdown of the IMEI number.
