A Mobile Equipment IDentifier (MEID) is a globally unique 56-bit identification number for a physical piece of mobile station equipment. Equipment identifiers are "burned" into a device and should be resistant to modification. They are used as a means to facilitate mobile equipment identification and tracking. Additionally, MEIDs are coordinated with International Mobile Equipment Identifiers (IMEIs), facilitating global roaming and harmonization between 3G technologies as a universal mobile equipment identifier.

The MEID is a 14-digit hexadecimal value. The MEID is capable of being transmitted over the air upon a request from the network. The MEID is composed mainly of two basic components, the manufacturer code and the serial number, as follows:

range description

All of these fields are defined as hexadecimal values with the following valid range.

  • RR - valid range A0 . FF - globally administered
  • XXXXXX - valid range 000000. FFFFFF
  • ZZZZZZ - valid range 000000. FFFFFF
  • C - valid range 0. F - Not transmitted over the air.

In the case of MEIDs for terminals designed to comply with both 3GPP and 3GPP2 specifications (i.e., multimode terminals), all these fields are defined as decimal values with the following valid range:

  • RR - valid range '99', '98', '97'. - globally administered
  • XXXXXX - valid range 000000. 999999
  • ZZZZZZ - valid range 000000. 999999
  • C - valid range 0 . 9 - Not transmitted over the air.


The MEID assignment process is compliant with the MOBILE EQUIPMENT IDENTIFIER (MEID) GHA (Global Hexadecimal Administrator). The latest Assignment Guidelines and Procedures as well as TIA_Global Wireless Equipment Numbering Admin Procedures can be found at http://www.tiaonline.org/standards/numbering-resources/mobile-equipment-identifiers-meid

MEID Assignments

The Global Hexadecimal Administrator (GHA) publishes a quarterly administrator's report, available upon request by materially- and directly-affected parties.

Application Process

There is a fee for filing MEID application assignments. The fee chart is available here. Applicants are required to request MEID assignments from the GHA by completing and transmitting FORM A. Once the form is received, the GHA will inform the applicant of the required fee. Assignments will NOT be processed until payment has been received.
