It was listed on the National Register of Historic Places in 1977 for having local significance in the themes of commerce, communications, engineering, and transportation.

[2] Its notability derives in part from its long service to Stillwater; nearly all goods shipped to and from the city passed through this station, and up to the 1920s it hosted critical telegraph and Railway Express Agency offices.

The building is also noted as a somewhat rare example of a combination freight and passenger station, and for the engineering of its internal wood construction.

[3] During this period in the 1880s, Stillwater was a busy trade center, handling traffic from miners and trappers from the north of town and from farmers and lumbermen from the west.

[1][5] In 1992 much of downtown Stillwater was listed on the National Register as a historic district, with the Freight House as a contributing property.
