57 Area Code

Where is 57 area code in USA?

The area code 57 does not belong to any region of the United States.

That is, this area code does not correspond to any area of the territory of North America. Therefore, if a call is made using the local prefix 57 in front of a phone number, a connection error will occur and the operator will indicate that the called phone does not exist.

Will the 57 prefix never exist?

It is not possible to know for sure.

In other words, telecommunications companies may decide to incorporate the 57 area code and make it a valid extension for a region of a U.S. state as a result of population or extension growth in a given region.
