What does STD Code mean?

Here STD stands for Subscriber Trunk Dialling code. Subscriber Trunk Dialling is the system of codes that are used for connecting with the landline telephones of various towns, villages and districts in India. The STD code for Delhi is 011, so whether you are calling from Kolkata, Kerala or Kashmir you will have to prefix your call to an Indian landline in the capital with 011.

Similarly if calling Delhi from abroad you will have to use the STD code. However, in this case you will need to drop the 0, replacing it with the India access code of +91. Therefore the code for connecting with a landline in Delhi from outside India will appear as +91 11. Note that the Delhi STD code is now just two digits.
