Feature Answer

What is Area Code 314?

Area code 314 is a North American telephone area code assigned to St. Louis, with primary coverage across St. Louis, Clayton, Central West End. It was one of the original NANP codes introduced in 1947, making it among the oldest area codes in the country. The code is local rather than toll-free, and it operates on Central Time.

For decades, 314 carried the full numbering load for the city. The code remains tightly bound to the city's identity, used by long-tenured businesses, institutions, and the kind of households who have held their numbers for generations.
