MBI Description
Mobile Identification Number (MIN) Block Identifiers, known as MBIs, were numbering resources assigned to Wireless Carriers and used by Wireless Service Providers (WSPs). A MIN is a 10-digit number that is similar to a North American Numbering Plan (NANP) number. The MIN consisted of a 6-digit MIN Block Identifier (MBI), followed by a 4-digit Mobile Subscriber Number (MSN). One MBI contains 10,000 MINs. Individual MINs were administered by the Wireless Carrier to which the MBI was assigned (the MBI Assignee).
