History of 314 Area Code
The 314 area code was one of the original area codes established in 1947 by the North American Numbering Plan (NANP). It initially encompassed a large section of eastern Missouri, including the state's largest city, St. Louis. Due to population and telecommunications growth, this large region was later reduced to primarily serve the immediate St. Louis metropolitan area.
The rapid exhaustion of available phone numbers forced the 314 region to undergo two major geographic splits. The first split occurred in 1996, which created the new 573 area code for the central and southeastern parts of Missouri. Following this, the remaining 314 territory was split again in 1999 to establish the 636 area code, which now serves the outer suburbs to the west, leaving 314 focused only on the City of St. Louis and its inner-ring suburbs.
Despite these measures, the need for new phone numbers continued to grow within the dense St. Louis area. To solve this, the 557 area code was approved as a mandatory all-services overlay for the 314 region. This overlay became effective on August 12, 2022, and currently works alongside 314, serving the exact same geographic area.
