An old New York phone exchange on 47th Street

March 8, 2021

Spotted on an unremarkable building on West 47th Street in the Diamond District: an old-school New York City phone exchange, in this case “MU.”

What does it stand for? Murray Hill, of course, the neighborhood where the real estate company that put up this plaque is based.

It’s getting harder to find these two-letter exchanges, which were replaced by numerals in the early 1960s. But they’re out there—especially in the boroughs outside Manhattan.

Upper Manhattan phone exchange mysteries

Tropy Washing Machines is a little neighborhood shop on 117th Street between Lexington and Third Avenues.

The sign is sweetly old-timey, but the AT exchange? It probably stood for Atlantic, according to this chart, but it’s a mystery.

Same with the TR exchange on this sign for Alexander Plumbing. The sign comes from an apartment building on Edgecomb Avenue in Harlem.

TRafalger covered parts of Manhattan, TRiangle was the exchange for a section of Brooklyn, and TRemont, of course, part of the Bronx.
