India's Telecom Circles / Service Areas

For a variety of purposes, India's telephony regulators have divided the country up into a number of regions, called 'Telecom Circles' or 'Telecom Service Areas'.

You will see reference to these telecom circles in various situations. For example: when looking for telephone numbers or telephone directories you will generally need to search by telecom circle. Or when reviewing telephone service plans and coverage areas for the telephone companies, you will see these may vary by telecom circle.

Also, if a telephone company wants to operate in a specific telecom circle, they must purchase a license for that circle, usually through an auction process.

At present, there are 22 Telecom Circles or Service Areas. They are broken down into 4 groups: 'metro circles' and then 'A', 'B', and 'C' circles.

The 'metro' circles cover very dense population centers in the very largest Indian cities: Delhi, Kolkata, and Mumbai.

The 'A', 'B', and 'C' circles cover various geographic territories of varying population sizes. 'A' circles are the largest in terms of population coverage. 'C' circles contain the smallest population.

The borders of the circles roughly correspond to the borders of the Indian states -- but there are exceptions. For instance, some smaller states are folded into larger neighboring states, some other smaller states are combined together to form one circle, etc.

Note that as of a July, 2007 memo from the India Department of Telecommunications, 'telecom circles' are now officially called 'telecom service areas'. Nevertheless, the terminology 'telecom circles' is still widely used.

India's Telecom Circles / Telecom Service Areas

Here is a list of India's 22 telecom circles, including Metro, A, B, and C category service areas. Officially, telecom circles are now called telecom 'service areas', but both terms used to mean the same thing.

The circles listed below are the officially recognized circles as stated by the India Department of Telecommunications. India telephone companies may or may not conform to this exact usage.
