Frequently asked questions

What is an STD code?

STD stands for Subscriber Trunk Dialling. The STD code is the area code that identifies the city or town (SDCA) of an Indian landline. Codes have 2 to 5 digits after the 0, for example 022 for Mumbai or 0832 for Panaji, and the whole number always has 10 digits without the 0.

How do I call an Indian landline from another city?

Dial 0, the STD code and the subscriber number. For example 022 2345 6789 for Mumbai. Inside the same city you only dial the subscriber number.

How do I call an Indian landline from a mobile phone?

From a mobile always dial the full number with the STD code and the 0 (for example 011 2345 6789 for Delhi), even if you are in the same city.

How do I call an Indian landline from abroad?

Dial your international access code (00 or +), the country code of India 91, then the STD code without the 0 and the number: +91 22 2345 6789.
