Does anyone remember the late 50's and early 60's when people only had 5 telephone numbers and no area code?

I remember from the 50s is exchanges, which were simple words whose first two letters represented the numbers on the dial. The exchanges were to make remembering the entire number easier.

Example: TRiangle 6-5459 was actually 876-5459. GLenview 2-7200 was actually 452-7200.
Prior to area codes, one had to use the operator to make a long distance call, asking for the exchange and number in Podunk, New Jersey, for example.

Having grown up in the 50s and 60s in a large metropolitan area, my recollections are the same as DG's -- 7-digit numbers like today, with the first two digits related to the first two letters of the the name of the exchange.

I spent a couple of months living in Nome, Alaska in 1977, where all local phone numbers were only 4 digits.

When I was in seminary, we had a really old refrigerator in our apartment. The refrigerator was so old, that the number to call in case it breaks down was a 5 digit number. no idea what the number is supposed to be nowadays. So my guess that the fridge was 40 years old was right!
