My childhood phone number in Brooklyn was a BU (28) number, though even when I was a child (1970s) the use of letter exchanges was basically a holdover of a more or less dead practice. (But the use of letter exchanges in phone numbers persisted for decades after that in New York City in store signs - I think there are still some in use today.) In Brooklyn, BU stood for "BUckminster". I had this idea that this was connected to there being a "Buckingham Road" and a "Westminster Road" in the area I grew up in (Ditmas Park West and environs) but I'm not sure if that was something I or someone I knew made up. I'm sure it had nothing to do with Buckminster Fuller.
