This occured very often in the 1950s and 1960s as the Bell System prepared for nationwide subscriber Direct Distance Dialing.
Before DDD, towns had strictly a local phone number. It could range anywhere from 3 to 7 digits long as local needs required.
But for DDD, everyone had to have a unique addressable 10 digit number. That meant everyone had to fit into a specified exchange block and area code. Thus, communities had their numbers changed. Someone who was perhaps 23 on an old system became (xxx) xxx-0023.
For many years, small communities needed only to dial 5 digits even when having a 10 digit number.
This was a lot more complex than it sounds. SxS exchanges had to have special handling to process 10 digits without adding unnecessary long switch trains. Independent telcos had to be worked in.
A lot of people objected to 10 digit phone numbers. Comedian Alan King made a big deal about them in his 1962 book. Critics said the many numbers (and loss of beloved exchange names) dehumanized telephone service. (Little did they know what was to come later!)
