Hi monkadeen-ga,

Of the seven digits, the first three are used to represent the
exchange. Therefore, the remaining four digits denote the telephone
number within the exchange.

In your example, the possible telephone numbers within the 537
exchange are numbered from 537-0000 through 537-9999. Therefore, there
are 10,000 possible different telephone numbers within the 537
