"Murray Hill" is a neighborhood in manhattan as mentioned in the article, I found a source with some more examples [0]: "For example, in a 1932 Manhattan phone directory, you can see the numbers listed by exchange. CH-elsea. ST-uyvesant. This was before direct dial, so there was no need to figure out what CH or ST converted to as numbers on your rotary dial; you’d simply ask the operator to connect you. Once people dialed directly, the first two letters became the first two numbers of the exchange. In that 1932 phone book, the number for the store Bergdorf Goodman, located near the Plaza Hotel, is given as Plaza 3-7300. That translates to 753-7300, which is still the store’s phone number today."
