For the town in Somalia, see. A mobile equipment identifier (MEID) is a globally unique number identifying a physical piece of mobile station equipment. The number format is defined by the but in practical terms, it can be seen as an but with digits. Regional code Manufacturer code Serial number CD R R X X X X X X Z Z Z Z Z Z C An MEID is 56 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. The check digit (CD) is not considered part of the MEID. The MEID was created to replace, whose virgin form was exhausted in November 2008.
As of TIA/EIA/IS-41 Revision D and TIA/EIA/IS-2000 Rev C, the ESN is still a required field in many messages—for compatibility, devices with an MEID can use a pseudo-ESN (pESN), which is a manufacturer code of 0x80 (formerly reserved) followed by the least significant 24 bits of the hash of the MEID. MEIDs are used on CDMA mobile phones. GSM phones do not have ESN or MIN, only an International Mobile Station Equipment Identity (IMEI) number. Contents. Obtaining the MEID on your phone Open your phone's dialler and type.#06# to get its MEID number. Administration The separation between international mobile equipment identifiers (IMEIs) used by GSM/UMTS and MEIDs is based on the number ranges. There are two administrators: the global decimal administrator (GDA) for IMEIs and the global hexadecimal administrator (GHA).
As of August 2006, the TIA acts as the GHA to assign MEID code prefixes (0xA0 and up), and the GSM Association acts as the global decimal administrator. The TIA also allocates IMEI codes, specifically destined for dual-technology phones, out of the RR=99 range.
Other administrators working under GSMA may also allocate any IMEI for use in dual-technology phones. Every IMEI can also be used as an MEID in CDMA2000 devices (as well as in single-mode devices designed with GSM or other 3GPP protocols) but MEID codes may also contain hexadecimal digits and this class of MEID codes cannot be used as an IMEI. Display formats There are two standard formats for MEIDs, and both can include an optional check-digit.
This is defined. The hexadecimal form is specified to be 14 digits grouped together and applies whether all digits are in the decimal range or whether some are in the range 'A'-'F'. In the first case, all digits are in the range '0'-'9', the check-digit is calculated using the normal base 10 algorithm, but if at least one digit is in the range 'A'-'F' this check digit algorithm uses base 16 arithmetic. The check-digit is never transmitted or stored.
It is intended to detect most (but not all) input errors, it is not intended to be a checksum or CRC to detect transmission errors. Consequently, it may be printed on phones or their packaging in case of manual entry of an MEID (e.g. Because there is no bar code or the bar code is unreadable). The decimal form is specified to be 18 digits grouped in a 5 5 4 4 pattern and is calculated by converting the manufacturer code portion (32 bits) to decimal and padding on the left with '0' digits to 10 digits and separately converting the serial number portion to decimal and padding on the left to 8 digits. A check-digit can be calculated from the 18 digit result using the standard base 10 algorithm and appended to the end. Note that to produce this form the MEID digits are treated as base 16 numbers even if all of them are in the range '0'-'9'. PESN conflicts Because the pESN is formed by a hash on the MEID there is the potential for hash collisions.
These will cause an extremely rare condition known as a 'collision' on a pure ESN-only network as the ESN is used for the calculation of the Public Long Code Mask (PLCM) used for communication with the base-station. Two mobiles using the same pESN within the same base-station area (operating on the same frequency) can result in call setup and page failures. The probability of a collision has been carefully examined.

Roughly, it is estimated that even on a heavily loaded network the frequency of this situation is closer to 1 out of 1 million calls than to 1 out of 100 000. 3GPP2 specification provides a solution to this problem by allowing the PLCM to be established by the base station. It is easy for the base station to ensure that all PLCM codes are unique when this is done. This specification also allows the PLCM to be based on the MEID. A different problem occurs when ESN codes are stored in a database (such as for ). In this situation, the risk of at least two phones having the same pseudo-ESN can be calculated using the and works out to about a 50 per cent probability in a database with 4,800 pseudo-ESN entries. 3GPP2 specifications (Revision C or higher) and have been modified to allow the replacement MEID identifier to be transmitted, resolving this problem.
Another problem is that messages delivered on the forward paging channel using the pESN as an address could be delivered to multiple mobiles seemingly randomly. This problem can be avoided by using (MIN) or IMSI based addressing instead.

Code to convert This short script will convert an MEID to a pESN.
That is not possible. MEID are for CDMA phones and the IMEI are for GSM phone. You have to understand that this phones although the same in feature have different network structures hence they cannot work interchangely meaning your CDMA phone cannot work for GSM and same goes with the other. The network frequency first of all is different and CDMA network device is different to GSM network device.
So even you can convert your MEID to IMEI you will see that your phone will not get any network because of the hardware installed on the devices are different. Leader Board Leading Today Pts Helpful 1. 200 83% Leading this Week Pts Helpful 1. 200 99% Leading this Month Pts Helpful 1.
Introduction systems require a (mostly) unique identifier for mobile devices. This identifier is specific to the device, and can't (easily) be changed, unlike a phone number (also known as a 'MIN'). There are two major identifier types - the older Electronic Serial Number (ESN) and the newer Mobile Equipment Identifier (MEID). Both identifiers have multiple presentation formats, and it can be tricky to determine how to actually identify a device if you're given a number in an unknown format.
This document aims to demystify ESNs and MEIDs. Electronic Serial Number (ESN) ESN's are managed by the. They are 32 bits long (that is, they can be described by a sequence of 32 1's and 0's), and identify the manufacturer of a mobile device and also the serial number assigned to the device by that manufacturer. The basic format for ESN's consists of 8 bits to specify the manufacturer and 24 bits to specify the serial number: The 8 bits of the manufacturer portion lead to 256 (2^8) different possible manufacturer codes. Some codes are reserved, however: numbers 0 through 18, 128, 250, and 255 are not to be used as normal ESNs. For manufacturer codes 0 through 17, 250, and 255, the manufacturer code is 14 bits and the serial number is 18 bits. Code 128 is discussed below in the pESN section.
It's usually most convenient to assume the standard format, and treat the reserved codes as exceptions. The 32 binary bits can be expressed in several ways, but the two recognized ways are:. 8 character hex code: A 2 character code to represent the manufacturer, and a 6 character hex code to represent the serial number. This is the most widely used format. Examples: 0x0106C01B8 (using 0x to indicate that a hex value follows), 0hC3B80 (using 0h to indicate that a hex value follows), e5ab0134b (without a prefix).
11 digit decimal code: A 3 digit decimal number to represent the manufacturer, and an 8 digit decimal number to represent the serial number. Examples: 9, 0. This is the second most widely used format. Beware: some programs (e.g.
Microsoft Excel) strip off leading 0's, making it difficult to tell whether you're looking at a decimal ESN. For example, a code of 2 might show up as. You might have as few as 8 digits (a manufacturer code of 000), or 9 digits (reserved manufacturer codes 001 through 009). Type Manufacturer Code Serial Number Binary 8 binary bits 24 binary bits Hexadecimal 2 hexadecimal numbers 6 hexadecimal numbers Decimal 3 decimal digits 8 decimal digits To convert between the two, break up your code (in either format) into a manufacturer block and a serial number block, convert the block to/from decimal/hex separately, then concatenate the two blocks. Make sure the blocks start and end with the correct number of hex characters/decimal digits.
Hex format to decimal format example: 0x0106C01B8 breaks into 0x10 and 0x6C01B8. 0x10 in decimal is 16, and 0x6C01B8 is 7078328. The converted ESN is 167078328. Decimal format to hex format example: 067078328 breaks into 067 and 078328.
067 in hex is 0x43, and 078328 is 0x131F8. The converted ESN is 0x43131F8. Some improper, but not-uncommon ways of representing ESNs are:. Converting the 11 digit decimal code above straight to hexadecimal (i.e. Not splitting it into 3 digits for the manufacturer and 8 for the serial number). This can be difficult to detect, as they are also 8 hex digits. If you have a set of 8 character hex codes, check the manufacturer codes.
If you consistently see an uncommon (for you) manufacturer, someone may have given you the ESN in this improper format. To correct this, convert the hex number back to decimal, then split up the manufacturer (3 digits) and serial number (8 digits). Converting the 8 character hex code above straight to decimal (i.e. Not splitting it into 2 characters for the manufacturer and 6 for the serial number). This is a little bit easier to detect than the previous improper format, as these will be a maximum of 10 decimal digits (2^32 - 1 =4,294,967,295). To correct this, convert the decimal number back to hex, then split up the manufacturer (2 characters) and the serial number (6 characters). Resources for ESNs:.
beware, this table is improperly labeled in multiple places. Should be properly labeled. Mobile Equipment Identifier (MEID) MEID's are also manged by the. These are 56 bits long, and like ESN's, identify the manufacturer of a mobile device as well as the serial number assigned to the device by that manufacturer. The MEID consists of 32 bits to specify the manufacturer and 24 bits to specify the serial number: The first 4 bits of the manufacturer code are 'reserved,' and restricted to just a few values. There can also be a 4 bit 'check digit' appended to the end, but this is not transmitted between the mobile device and the CDMA system (according to ) and is not common to see. There are two proper ways to represent MEIDs:.
14 character hex code: An 8 character hex code to represent the manufacturer (2 for the reserved portion, 6 for the actual manufacturer portion), and a 6 character hex code to represent the serial number. This is the most widely used format. Examples: 0xA6F2 (using 0x to indicate that a hex value follows), 0hA00000003FF642 (using 0h to indicate that a hex value follows), ff000000b2c63a (without a prefix). 18 digit decimal code: A 10 digit decimal number to represent the manufacturer, and an 8 digit decimal number to represent the serial number. Example: 10201020. Type Manufacturer Code Serial Number Binary 32 binary bits 24 binary bits Hexadecimal 8 hexadecimal numbers 6 hexadecimal numbers Decimal 10 decimal digits 8 decimal digits To convert between the two, break up your code (in either format) into a manufacturer block and a serial number block, convert the block to/from decimal/hex separately, then concatenate the two blocks. Make sure the blocks start and end with the correct number of hex characters/decimal digits.
Hex format to decimal format example: 0xA6F2 breaks into 0xA1000000 and 0x9296F2. 0xA1000000 in decimal is, and 0x9296F2 is 9606898.

The converted manufacturer block is OK (10 decimal digits), but the serial number block is one short (it's 7 instead of 8), so we prepend a 0 to it. The converted MEID is 09606898 (18 decimal digits). Decimal format to hex format example: 10201020 breaks into and 10201020. In hex is 0xA0000000, and 10201020 is 0x9BA7BC. The converted MEID is 0xA00000009BA7BC. Some improper, but not-uncommon ways of representing MEIDs are:. Converting the 18 digit decimal code above straight to hexadecimal (i.e.
Not splitting it into 10 digits for the manufacturer and 8 for the serial number). To correct this, convert the hex number back to decimal, then split up the manufacturer (10 digits) and serial number (8 digits).
Converting the 14 character hex code above straight to decimal (i.e. Not splitting it into 8 characters for the manufacturer and 6 for the serial number).
To correct this, convert the decimal number back to hex, then split up the manufacturer (8 characters) and the serial number (6 characters). Tip: For MEIDs, it can be difficult to convert to/from hex/decimal an improper code, since the numbers are so large (they cause an error if the 'integer' type used in whatever conversion routine is not big enough). If you're using Excel:. Resources for MEID's:.
Pseudo ESN (pESN) The reserved ESN manufacturer code 128 is for 'pseudo ESN's,' which allow legacy equipment to recognize MEIDs. PESN's are ESN codes that always begin with 0x80 in the hex format (or 128 in the decimal format, but it is much more convenient to work with the hex format for pESNs). To generate one, you apply the to the MEID, and take the last (least significant) 24 bits (6 hex numbers) of the result, and append them to 0x80. This can be tricky to do, especially if you're using something like Microsoft Excel. You want to apply SHA-1 to the number representing the MEID, not the string representing the MEID. You'll need to process it byte-by-byte, so you must give it two hex numbers at a time (since two hex numbers make a byte) and make sure they are interpreted as numbers and not ASCII characters. This VBA script, which can be used as a user-defined Excel function, does the trick: Examples:.
Given MEID 0xA329, make a pESN. SHA-1 on A329 gives e3be267a2cd5c861f3c7ea4224df829a3551f1ab. Take the last 6 hex numbers of this result, and append it to 0x80 - the result is 0x8051F1AB. Given MEID 0xFF56, make a pESN. SHA-1 on ' FF56' gives ffce4beab4c2a7933c0d6d21b21cf21a0e0737e1.
Take the last 6 hex numbers of this result, and append it to 0x80 - the result is 0x800737E1.
