Locations for Area Code - 314

Area code 314 covers the city of St. Louis and inner suburbs in eastern Missouri. Established in 1947, it was one of the original North American area codes. While its territory has been reduced through splits and overlays—now paired with area code 557—314 remains synonymous with St. Louis’s historic and cultural center. The city’s influence in music, sports, education, and commerce keeps 314 in the spotlight. Ten-digit dialing is required. Widely used in branding, apparel, and local pride initiatives, area code 314 stands as a unifying emblem for the Gateway City and its storied legacy.
