County and City Covered by Area Code 314

The 557 overlay serves the same geographic territory as 314, so a community within this region can have either a 314 or 557 number. Existing 314 customers retained their numbers when 557 was introduced.
History & Background of Area Code 314
Area code 314 was introduced in 1947 as one of the original 86 North American area codes, serving eastern Missouri, including St. Louis. It was Missouri's first area code and originally covered a much larger geographic area than it does today.
As demand for telephone numbers increased, the original territory was reduced through geographic splits, while a later overlay added new numbering capacity without requiring existing customers to change their numbers.
- 1947: Area code 314 was established as one of the original North American area codes, serving eastern Missouri and the St. Louis area. It became the first area code assigned to Missouri.
- 1996: A geographic split created area code 573, removing a large portion of the eastern and southeastern Missouri territory from 314.
- 1999: A second major split created area code 636, further reducing the 314 service area and concentrating it around St. Louis and its inner-ring suburbs.
- August 12, 2022: Area code 557 was introduced as an overlay to 314, providing additional telephone-number capacity while allowing existing 314 customers to retain their numbers.
- Today: 314 and 557 serve the same geographic territory, covering St. Louis City and parts of St. Louis County, including communities such as Clayton, Florissant, and Kirkwood.
- Time Zone: The 314 region operates in the Central Time Zone (CT).
