What is IMEI? Checking the IMEI and distinguishing the real and fake IMEI is one of the quite effective ways for you to identify whether a product is genuine or a floating product, of unknown origin, even an illegal one. However, how to realize, what is a real IMEI, a fake IMEI is something that certainly not everyone knows.
The IMEI code is a "passport", which identifies a product or a mobile device. There are never two identical IMEIs for the same phone, so checking a real - fake IMEI is one of the most important and effective ways to identify that device.
As we know, the structure of an IMEI consists of 4 parts ( IMEI = TAC + FAC + SNR + CD ). Inside:
The formula is determined as follows:
ATTENTION:
For example:
After step 3, the total value found is:
Specifically:
We have an IMEI range as follows: 49015420323751 X (490154-20-323751-X) -> Find X ?
| IMEI | 4 | 9 | 0 | first | 5 | 4 | 2 | 0 | 3 | 2 | 3 | 7 | 5 | first | X |
| Duplicate the value | 18 | 2 | 8 | 0 | 4 | 14 | 2 | ||||||||
| Add up the sum | 4 | 1 + 8 | 0 | 2 | 5 | 8 | 2 | 0 | 3 | 4 | 3 | 1 + 4 | 5 | 2 |
After step 3, our sum is:
4 + 1 + 8 + 0 + 2 + 5 + 8 + 2 + 0 + 3 + 4 + 3 + 1 + 4 + 5 + 2 = 42 -> not divisible by 10.
The divisor for 10, bigger and closest to 42, is 50 -> CD number = 50 - 42 = 8 .
So X = 8 and our complete IMEI code is 49015420323751 8 .
With this calculation formula, you can easily check whether the last number (CD number) of an IMEI code matches or not, is it standard with the remaining 14 numbers in the sequence?
There are many devices, whether genuine, genuine, but faulty, used, or for some reason, their IMEI code has been changed to hide their true information. And here is how to help you find the "error" in that IMEI code.
