STD codes of India: area code of every city and town

The eight two-digit codes

The biggest cities have the shortest codes, so that their landline numbers can be eight digits long.

How STD dialling works

• STD stands for Subscriber Trunk Dialling: calling a landline in another town without an operator.
• An STD code is written with a 0 in front, like 0161. The 0 is the trunk prefix; the code itself is 161.
• The code (without 0) and the landline number together are always 10 digits. So a city with a 2-digit code has 8-digit numbers, and a town with a 4-digit code has 6-digit numbers.
• From a mobile phone, always dial the 0, the code and the number, even for a landline in your own town.
• From a landline, calls to any mobile number need a 0 in front of the 10 digits. This rule began on 15 January 2021.
• From abroad, dial +91, drop the 0, then the code and the number.

Why some states share a page

The list follows the National Numbering Plan 2003, which arranged codes by telecom region. Places now in Jharkhand, Chhattisgarh, Telangana, Sikkim, Ladakh, Puducherry and Chandigarh appear in the page of the neighbouring state they were grouped with. Use the search box if you are not sure where a town is listed.
