About the 314 region
314 covers St. Louis in Missouri, including Florissant, Crestwood, Hazelwood and Kirkwood. The code has been in service since 1947 and is one of the original North American area codes.
As the St. Louis region grew, 314 ran low on available numbers, so 557 was added as an overlay code over the same geographic area. Both codes are local to each other and 10-digit dialing applies throughout.
