What are IMEI, ESN and MEID identifiers?

IMEIs, ESNs and MEIDs are numbers and codes used by the mobile producers in order to ensure the unique identificator for each devices.  Generally speaking each device have assigned one IMEIs, ESN or MEID.

What is the MEID Number?

The MEID Number (Mobile Equipment Identifier) is a unique 56-bit identification code for CDMA mobile devices. The MEID number is permanently stored in the device. The MEID is a replacement for ESN (electronic serial number) since 2006. The MEID Number consists of the following parts:

  • 8-bit regional code (RR)
  • 24-bit manufacturer code
  • 24-bit number assigned by the manufacturer
  • (CD) is not considered part of MEID

Parts of MEID Number

We can distinguish two standard formats for MEIDs identifier, and both may contain an optional check-digit:

  • Hexadecimal Form – 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.  When the all elements are from '0'-'9' range than the check-digit is converted by using the normal base 10 Luhn algorithm. In the second case when at least one digit is A - F range the check-digit algorithm uses base 16 arithmetic.
  • Decimal Form – 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. A check-digit can be converted  from the 18 digit result using the base 10 Luhn algorithm and appended to the end.  The decimal form is specified by 18 digits grouped in a 5 5 4 4 pattern .

What is the IMEI Number?

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 IMEI is only used for identifying the device and has no permanent or semi-permanent relation to the subscriber. Number is used by the GSM network to identify valid devices and therefore can be used for stopping a stolen phone from accessing the network in that country.

What is ESN?

ESN - Electronic Serial Number is a unique 32-bits identification number embedded by manufacturers in wireless phones. In addition to being programmed into the phone's microchip, the ESN typically is found on a label under the cellular phone's battery.
