WWV received its call letters from a block of call signs that the Department of Commerce, which regulated radio at this time, had issued to government stations—two months previously it assigned WWG, WWO, WWU, WWQ and WWX to five Post Office Department stations ("New Stations: Government Stations", Radio Service Bulletin, August 1, 1919, page 4). WWV is one of a small number of radio stations west of the Mississippi River with a call sign beginning with W instead of K, as the original call was kept when the station moved to Colorado. As a government station, WWV, does not fall within the FCC's jurisdiction with respect to call signs, and an FCC regulation reserves the call signs WWV, WWVB through WWVI, WWVL and WWVS for "standard frequency" stations ("Title 47:Subpart D:§ 2.302: Call Signs" （页面存档备份，存于互联网档案馆）, Code of Federal Regulations, Government Printing Office).
