The station's studios and offices are located in the Brine Broadcasting Center on Wampanoag Trail on the East Providence–Barrington line.

[2] WPRO-FM is unique in the Providence media market in keeping the same call sign since its sign-on in 1948; and the same format, top 40, since 1974.

An amended application was filed January 15, 1941, and was finally granted by the Federal Communications Commission (FCC) on June 12, 1947, with its new frequency of 92.3 MHz in the new FM band.

(In the early days of broadcasting, it was common for department stores to own radio stations, to provide programming for customers who bought receivers.)

On April 29, 1974, at 3:00 pm, WPRO-FM changed formats from easy listening, joining its AM counterpart as a top 40 outlet.
