Each decade the phone numbers grew longer as the area grew in population. Gone now are four digit phone numbers. The list above shows five, six, and seven digit numbers. Seven digit numbers use the GLendal exchange prefix. Later CHerry would be added as the area grew still more. In 2004 exchange names are but a memory, and people once more struggle seven and ten digit telephone numbers. Until about 1990, all area codes had either zero or one as the middle digit. Today an area code can be any number, and with the proliferation of cell phones, FAX machines, dialup modems, etc., increasing demand ever more for phone lines, the day of the 10 digit phone number has arrived. Area codes no longer give much indication of which area the country a person lives in, and there are now too many to remember anyway.

But in 1951 yet most households only had one phone, and long distance was a luxury. So the numbers were still relatively short.
