[3] United States telephone numbers often included letter prefixes and telephone exchange names, which were more easily memorable for users than long digit sequences.
For example, 234 235-5678 is a valid telephone number; with area code 234, central office prefix (exchange) 235, and line number 5678. The number 234 911-5678 is invalid, because the central office code must not be in the form N11.
