The State Telephone Codes, basically, allow inter circle calls that are considered long distance calls. Currently the Indian Government is working to integrate the whole country in one telecom circle including the state of Himachal Pradesh. At present for long distance calls to any place in Himachal Pradesh, one need to prefix the area code with a zero. For instance, the area code of Shimla in Himachal Pradesh is 177. That is why to dial any number in Shimla from outside Shimla one has to dial 0177 first. This is immediately followed by the individual phone number of a valid subscriber.
