81 Area Code

Where is 81 area code in USA?

The area code 81 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 81 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 81 prefix never exist?

It is not possible to know for sure.

In other words, telecommunications companies may decide to incorporate the 81 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.
