Area Code 573 History and Coverage

Area code 573 was introduced in 1996 through a geographic split of Missouri’s 314 numbering-plan area. The change addressed a shortage of available telephone numbers in 314, while the St. Louis metropolitan area kept 314 and the remaining territory received 573. It became one of the state’s major regional codes during a period when expanding telecommunications services increased demand for numbering resources.

The coverage of this area code coincides with some important transport and settlement routes rather than a metropolitan market alone. These include towns on the Mississippi River, north-central Missouri, the central Missouri river country, and the southeast portion of the state. Transport routes, ports, state government, universities, agriculture and regional medical facilities have contributed to the formation of such a dispersed pattern of connections within the territory.

There has been another number allocation in this region that led to the addition of the 235 area code as an overlay for 573. Together, they cover the same geographic region, with 573 being the older one, established through the 1996 geographic split of the area. The geographic coverage of the two extends towards the Bootheel and Iowa.
