Thinking now (given what your number was) that
maybe the word portion didn't take up the entire
prefix. I do seem to recall her indicating that
designation may have been for the neighborhood
and not the entire city.

Just the first two letters of the word.
We started out with just three numbers.  "429".
It was that way for several years, then went to five numbers, then they added on "Fairfax", but we just used the FA then the five numbers.

"@phxsparks please correct me if I am wrong on the relay business".  

Good thread and post.  Early dial telephone systems were interesting.  As a small child I grew up in rural America.  We had a phone with no dial.  It was a candle stick phone.  You picked up the ear piece and tapped the lever twice.  The operator would come on the line.  "Number Please"?  We could just say we wanted Mr. Lemmon who was the town barber and she would connect.  We could say grocery store and she would connect.  With a patch cord at the switchboard.

My grand parents had a crank type Kellogg telephone mounted on the wall in a Oak cabinet.  When you wanted the operator, you pick up the ear piece and stood next to the microphone and cranked the phone the operator would come on the line.  They had batteries in a galvanized steel bucket on the floor, that powered the phone.  The phone company would come change the batteries when the voltage got too low.  I remember being 5 years old visiting Grammy and she called my Mom so we could talk on this crank phone.  They look like the photo below.

Where @Aquarius mentioned the relays caught my attention.  This is a fascinating story.  I am lazy tonight so here are some snippets from wiki for more information.

Strowger, an undertaker, was motivated to invent an automatic telephone exchange after having difficulties with the local telephone operators, one of whom was the wife of a competitor. He was said to be convinced that she, as one of the manual telephone exchange operators, was sending calls "to the undertaker" to her husband.[1]

He conceived his invention in 1888, and was awarded a patent for an automatic telephone exchange in 1891. The initial model was made from a round collar box and some straight pins.[2]

While Almon Strowger devised the initial concept, he was not alone in his endeavors and sought the assistance of his brother Arnold, nephew William, and others with a knowledge of electricity and financing to realize the concept. The Strowger Automatic Telephone Exchange Company was founded in 1891.[2]

The company installed and opened the first commercial exchange in his then-home town of La Porte, Indiana on November 3, 1892, with about 75 subscribers and a capacity for 99. It used two telegraph type keys on the telephone, which had to be tapped the correct number of times to step the switch, but the use of separate keys with separate conductors to the exchange was not practical for a commercial system. Early advertising called the new invention the "girl-less, cuss-less, out-of-order-less, wait-less telephone". [3]

The Strowger Automatic Telephone Exchange Company became the Automatic Electric Company, which Strowger was involved in founding, although Strowger himself seems not to have been involved in further developments. The Strowger patents were exclusively licensed to the Automatic Electric Company. Strowger sold his patents in 1896 for US$1,800 and sold his share in Automatic Electric in 1898 for US$10,000. His patents subsequently sold for US$2.5 million in 1916. Company engineers continued development of the Strowger designs and submitted several patents in the names of its employees.

The Strowger system was widely used until the development of the more reliable crossbar switch, an electromechanical switch with a matrix of vertical and horizontal bars and simpler motions.
