Enter your Identifier Number (IMEI) and it will convert to every format of device unique codes such as MEID and ESN. This calculator uses also pseudo ESNs (pESN), ESNs, and MEID numbers in both decimal and hexadecimal forms. You may use this tool in order to convert between IMEI, MEID and ESN, and to view both decimal and hexadecimal formats. This calculator may be very helpful especially when you are trying to activate your device with a carrier that requires unique identifier in a strictly specified format. Answer goes here. 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 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 then 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.

The number format is defined by the 3GPP2 report S.R0048 but in practical terms it can be seen as an IMEI but with hexadecimal digits. An MEID is 56 bits long (14 hex digits). It consists of three fields, including an 8-bit regional code (RR), a 24-bit manufacturer code, and a 24-bit manufacturer-assigned serial number.

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. 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.

Find IMEI or the serial number and other information for your iPhone, iPad and iPod touch Learn where to find your iOS device’s serial number, International Mobile Equipment Identity (IMEI) number, Mobile Equipment Identifier (MEID), Cellular Data Number (CDN) and Integrated Circuit Card ID (ICCID) number. Every iPhone, iPad, and iPod touch has a serial number.

IOS devices with cellular connectivity also have other unique identifiers including an International Mobile Equipment Identity (IMEI) number, Mobile Equipment Identifier (MEID), Cellular Data Number (CDN), and Integrated Circuit Card ID (ICCID) number. You might need this information when you register your device or request support. You can find this information: • • • iOS devices On most iOS devices, you can tap Settings > General > About to see your device’s serial number, IMEI/MEID, and ICCID. If you’re using iOS 6 or later, you can tap and hold on the number to use the copy option, then paste this information into Apple registration or support forms. If you haven’t yet set up your device, you can find the IMEI and ICCID by tapping the Info icon on the lower-right corner of the iOS setup assistant “Hello” screen. If you can’t get to your About screen, use another option below based on the type of device you have.
