The IMEI (International Mobile Equipment Identity) is a unique number to identify GSM, WCDMA, and iDEN mobile phones, as well as some satellite phones. The decimal form is specified by 18 digits grouped in a 5 5 4 4 pattern. A check-digit can be converted from the 18 digit result using the base 10 Luhn algorithm and appended to the end.

Decimal Form вЂ“ this standard is converted by changing the manufacturer 32-bits code to decimal and padding on the left with '0' digits to 10 digits and separately converting the serial number to decimal and afterwards padding on the left to 8 digits.In the second case when at least one digit is A - F range the check-digit algorithm uses base 16 arithmetic. When the all elements are from '0'-'9' range than the check-digit is converted by using the normal base 10 Luhn algorithm. Hexadecimal Form вЂ“ this standard is expressed in 14 digits grouped together and applies whether all digits are in the decimal range or whether some are from the range A - F.We can distinguish two standard formats for MEIDs identifier, and both may contain an optional check-digit: 24-bit number assigned by the manufacturer.The MEID Number consists of the following parts: The MEID is a replacement for ESN (electronic serial number) since 2006. The MEID number is permanently stored in the device. The MEID Number (Mobile Equipment Identifier) is a unique 56-bit identification code for CDMA mobile devices. Generally speaking each device have assigned one IMEIs, ESN or MEID. Following the formula above, I calculated his 15th digit and was able to confirm that his device was fully activated.IMEIs, ESNs and MEIDs are numbers and codes used by the mobile producers in order to ensure the unique identificator for each devices. I had an elderly customer who did not have the IMEI but provided the ESN to me. The second occasion was during a job that required activating phones at times. The first was for my LG G5, and I was able to validate it through an IMEI checker, which did display the correct LG G5 variant-and was later sold to a customer with that IMEI, and who has not complained since our transaction. This is just an example, but shows exactly how one would use a real MEID/ESN to calculate the 15th digit (to get the IMEI). The number that we added to the 62 is our check digit: Now add to the summed number until it is divisible by 10 and results in a whole number: You will then double every second digit of the MEID:ДЄdd up all the digits as though they were all single numbers:ДЎ+4 + 3 + 8 + 5 + 1 + 2 + 7 + 1 +6 + 9 + 2 + 2 + 6 + 4 + 1 + 0=62 I will give you a simple visual showing of how it is done. It is a public domain algorithm commonly used today for numerous devices. Luhn's algorithm is a way to obtain that 15th digit. The IMEI will have the same first 14 digits as an MEID or ESN, with a final 15th digit called a check digit. If you have either the MEID or ESN, you have the ability to calculate your IMEI.ДЄn MEID or ESN will be 14 digits, while an IMEI will be 15 digits. But after putting in a GSM SIM card, nothing changed. The LG G5 had been on US Cellular for about two days, so maybe this was a simple solution. Reading through some forum threads, some people stated that popping in a GSM SIM card would allow me to see an IMEI in the settings if the device was on a CDMA network previously. There was nothing on the back, and the settings only showed an MEID and ESN. I recently had an issue with a brand new LG G5 (US992) device that comes factory unlocked, but is branded for US Cellular. There may be other reasons, but this would be the most common. However, there will be times that neither provide an IMEI.ДЄs for what it is needed for, most of us would have to give it to a carrier to register our device on a network before we can use the network. Other times you may even be able to find this printed on the back of a device. But there will be times when a device will just not show this information.ДЄs stated above, most of the time an IMEI can be easily found in your device settings. For a lot of people, this can be found within the device.

This is a short article on how to get an IMEI number from a MEID or ESN, which should be the same.
