Buy a Local Phone Number – Area Code 573 (Columbia, Missouri)

Formed in the mid‑1990s from a split of 314, 573 covers most of eastern and south‑central Missouri outside St. Louis, linking Columbia, the capital at Jefferson City, and river towns like Hannibal and Cape Girardeau. The change answered surging demand from wireless and dial‑up lines; later, number pooling and rate‑center adjustments in the 2000s conserved prefixes. Relief planning has been revisited by the Missouri PSC and NANPA, but conservation and the shift to mobile/VoIP postponed any overlay.

• Higher education and research anchored by the University of Missouri; engineering at Rolla.
• State government services in Jefferson City.
• Healthcare systems and insurance in Columbia and Cape Girardeau.
• Agriculture, river logistics, and food processing along the Mississippi and Missouri corridors.

Columbia’s telecom shifted from a single incumbent to competitive local exchange carriers after the 1996 act, with co‑ops and independents (Socket, Co‑Mo Connect, Sho‑Me) extending fiber backbones and last‑mile access. As customers migrated to mobile, central‑office codes were pooled and reclaimed, stretching the numbering plan. Ten‑digit dialing is now common practice across carriers, and ongoing planning emphasizes number portability and E‑911 reliability. Today, the 573 footprint links college towns, military installations, and farm communities under a shared communications map rather than a single media market.
