Number of area codes in the United States
How many area codes are there in the US?
800 possible combinations
It is extremely interesting to know that there are 800 possible combinations associated with the area codes. Anyway, some of these combinations are not available to be introduced. Keep in mind that combinations include: easily recognizable codes (the 2nd and 3rd digits are the same, such as 233), N11 (such as 211, 311, 411), N9X (such as 392, etc.), 37X (such as 374, etc.), and 96X (such as 965). The main idea is that these codes are either used as service codes or reserved for unanticipated purposes.
