Therefore if a mobile device is reported to be stolen or claimed for insurance, then the carrier of the network blacklists the ESN dispensed to the device. Blacklisted ESN devices won't obtain network access. CheckESNFree.com is an online ESN Checker tool which is helping thousands of buyers and reseller in getting.

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). 2007 Quickbooks Pro 3 User Edition Atlas more.

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. Kenan And Kel Full Series Of Laverne. 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'.
