In the days of old an ordinary telephone number had four digits, while large cities used five-digit numbers. To reach a person beyond city bounds by phone, you would normally have to tell the operator the name of the city and a number.
Phone numbers looked like this in the middle of the 20th century because of telephone exchanges—the hubs through which an area’s calls would be routed.
Special telephone numbers are used for high-capacity numbers with several telephone circuits, typically a request line to a radio station where dozens or even hundreds of callers may be trying to call in at once, such as for a contest.
Alphanumeric phone numbers began to die out in the 1960s-1970s when it was recognised that there were more telephone-numbers than exchanges to handle them and in the 1960s and 70s, communications companies started switching to all-digit numbers, the kind we know today.
The number has a rich history, dating back to at least 1930, when seven-digit dialing replaced the earlier five-digit and two-letter formats. It is also famously referenced in the Glenn Miller song of the same name.

Another historic step in the history of the telephone was made in the early 1960s, when all-number calling (ANC) appeared as a new, uniform telephone numbering system in Canada and in United States. ANC numbers consist of seven figures and no letters.
