May 2002 - new service to Dorokha Dungkhag Office
Bhutan Telecom implemented a radio link (VHF) to Dorokha Dungkhag in the
Phuentsholing area. +975 5 290001 was assigned as the number to reach the
radio base. This implies the introduction of a new subscriber numbering
range.

late 1990s? - numbering change?
Some telephone numbers in Bhutan, generally those in the capital city of
Thimphu, began to appear as +975 2 xxxxxx. That is, area code 2 for
Thimphu, followed by a 6-digit subscriber number. No official information
or confirmation of numbering changes is available. Bhutan numbers had been
appearing in the past as 5 digits without area code (Thimphu might have
been the only dialable centre until recently).
An April 2002 announcement from BTA, the national carrier, confirmed that
Bhutan was operating under a numbering plan of 1-digit area codes followed
by 6-digit subscriber numbers. Previously available telephone numbers listed
for Bhutan tended to be contradictory as to the actual area code and
subscriber number lengths.
