A journey becomes more happy and comfortable if you are well equipped. While traveling to a city for the first time, don't forget to take along with you the maps, important contacts, a handbook of the local language and a fare chart of the local transport. If you are traveling to a place in another country, for the first time, being extra cautious is advisable. For example, before coming to West Bengal, in India, make sure to have all the important STD codes of the state with you, especially if you have to call on a landline number in any of its cities. If you have to call on a fixed line number of any city in West Bengal, from abroad, you will need the ISD code.
Talking about STD codes, before dialing any fixed line in a city, other than the one you are in, you will have to affix the STD (Subscriber Trunk Dialing) code of former city, ahead of the phone number. In the same way, you will have to affix the ISD (International Subscriber Dialing) code to the fixed line number of a city, if you are calling from abroad. In case you are dialing a mobile/cell phone number, the STD code will be zero (0) and the ISD code will be 091, throughout the country. in the following lines, we have provided the complete lost of the STD and ISD codes of West Bengal.
