When you go to a new place for the first time, it is advisable to be on the safer side. Carrying maps, having important phone numbers, etc are some of the precautions that are usually taken while in a new city. However, if you traveling to a state in another country, for example Maharashtra, you need to have STD codes of the state with you, especially if you have to call on a landline number of any of its cities. If you calling on a fixed line number of any city in Maharashtra from abroad, you will need the ISD code.

STD (Subscriber Trunk Dialing) Codes will be affixed before the landline number of a person, if he is staying in some other city than the one you are in. In case you have to dial the landline number of a person in the state, from abroad, you will have to prefix the ISD (International Subscriber Dialing) Code. In case of mobile, the STD code (0) as well as ISD code (091) is same not only throughout Maharashtra, rather the whole of India. Explore the STD and ISD codes of Maharashtra.
