MIN (Mobile Identification Number)
are numbers that uniquely identify mobiles working under TIA
standards for Cellular and PCS technologies. (e.g. EIA/TIA–553 analog, IS–136 TDMA or IS–95
CDMA).
IRM (International Roaming MIN) are
MIN with the following format: 0-XXX+6D or 1-XXX+6D. The IRM
concept was expanded in March 2004 to include MIN codes with the
format XXX-0+6D and XXX-1+6D. They are now also available for
assignment.
The 4 digit prefix of an IRM is allocated
by IFAST (International Forum
on ANSI-41 Standards Technology) that attempts to facilitate international roaming by
minimizing conflicts with North American MIN.
The last 6
digits of an IRM are allocated by the carrier.
