Look for the area code, that is the beginning 3-digits of the number, you would like more information for. There are 176 area codes in our database, we have a range of details for each of the corresponding subcodes that are linked to these.

Area codes, often given the acronym NPA (Numbering Plan Areas) , are allocated using the North American Numbering Plan (NANP). This divides the areas of the member countries into sections with the 3-digit code. The system covers primarily North America and the Caribbean.

The numbering plan does not allow the use of 0 or 1 as these are normally used for international codes or historically operator assisted phone calls.
