2004-2005 - national renumbering

A new numbering plan will take effect in Mongolia during 2004-2005. Specific time frames for changes were not known.

For calls into Mongolia, a carrier selection code digit immediately follows country code +976:

The carrier selection code digit is:

• 1: Mongolia TeleCom (MT)
• 2: Mongolian Railway Authority (MRA)

Therefore a call into Ulaanbataar via Mongolia Telecom are dialled from other nations in the +976 1 1 xxxxxx format. Calls to a Mongolian Railway number are of format +976 2 1 xxxxxx. Carrier selection codes do not apply to Mobile numbers in +976 9... format.

Within Mongolia, 01+ trunk prefix followd by area code and subscriber number is used to reach Mongolia Telecom numbers. 02+ is used in a similar manner to dial Mongolia Railway Authority numbers.

Area code digits will be as follows, where C represents the carrier selection digit 1 or 2 as dialled from outside Mongolia:

Region/service                Area code format
==============                ================
Capital region - Ulaanbaatar     +976 C 1 ...
Capital region - Suburban        +976 C 2 ...
Central and Northern regions     +976 C 3 ...
Western region                   +976 C 4 ...
Eastern region                   +976 C 5 ...
Mobile                           +976 9 ...

Area codes (excluding country code, carrier selection and prefixes) will have 1 to 4 digits.

Only Ulaanbaatar will be based on a single-digit area code (+976 C 1).

The only new format 2-digit geographic area code assigned is for Baganuur (+976 C 21).

Mobile numbers will be based on 2-digit area codes.

Mongolia is divided into Aimags (provinces) - the aimag centre (provincial capital) will have 3-digit area codes, with third digit '2' (e.g. +976 332 for Arkhangai's capital Tsetserleg City).

4-digit area codes will be for smaller ("Sumun") centres within the Aimag.

18 November 2000 - national renumbering

Mongolia changed to a new national numbering scheme 18 November 2000. The highlights:

• 001+ became the international prefix from Mongolia (formerly 00+)
• For calls into Mongolia, a carrier selection code digit follows country code 976, before the area code and subscriber number.
• There was no permissive period for the change. New numbering took immediate effect, without parallel operation of the old numbering plan.

Details on this change are reported on KDDI bulletin 2000 #00007.
