Seven-Digit Dialing Starts – Nov. 6, 1966

Remember these? I kinda miss them.
Sixty years ago tomorrow, Lorain Telephone Company transitioned from five digit phone numbers with a two letters exchange prefix to a seven -digit dialing system.

It was the end of the old two letter five-figure numbers that had been around since the mid-1950s. Here's an ad from November 1956 explaining that system when it was new.

But why the change in November 1966? The main reason was that since the first and last holes of the dial on the telephone phone have no letters, there simply wouldn't be enough combinations of two letters and five numbers to meet the demand in the ensuing decades. A series of ads in the preceding months made the case and got the dialing public ready for the change.

  3. Over in Pennsyltucky we didn't get 7-digits until much later, and when we did, the mnemonics had been dropped and you simply remembered the extra numbers. As a result, the Cleveland phone numbers listed in various TV ads were a mystery to me. I mean, "GArfield-1-2323" - really? What does -that- mean?
