The stability of the time scale now allows the station time to be typically kept within ±0.02 μs (20 ns) of the national time standard in Boulder, and to agree to within 1×10⁻¹⁴ in frequency.

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", Code of Federal Regulations, Government Printing Office).

DX Listening Digest 5-016 (January 26, 2005) edited by Glenn Hauser: "For a short time, a broadcaster from Atlanta named John Doyle's voice was used on the broadcast; the voice announcement was then re-recorded by a radio personality in the San Francisco area named Lee Rodgers ... NIST Radio Station WWVH in Kauai, Hawaii, has a similar broadcast using a female voice. The announcer, Jane Barbe, did pass away several years ago." — Glenn Nelson, NIST Radio Stations WWV/WWVB
