Sikkim Telephone Codes

The entire territory of Sikkim can be divided into two telephonic zones, with two Sikkim telephone codes. Sikkim is sparsely populated and many areas being largely rural and quite remote amidst the mountains make telecommunication a rarely used civic amenity. The area of Sikkim, although large, can be catered to with only two STD zones based on the two cities of Gangtok and Gauzing. For callers from abroad, the relevant STD is to follow the ISD code of India, which is +91.
