List of Missouri area codes

From Wikipedia, the free encyclopedia

This is a list of telephone area codes in the state of Missouri.

314: St. Louis and many of its immediate suburbs

417: The southwestern corner of Missouri

573: Eastern Missouri excluding the St. Louis area

636: Greater St. Louis area, including St. Charles, Jefferson, and western St. Louis counties; forms a ring surrounding the immediate St. Louis area (314)

660: Northwestern Missouri excluding the Kansas City and St. Joseph metropolitan areas

816: The Kansas City and St. Joseph metropolitan areas

The two original area codes for Missouri in 1947 were 314 and 816. Area code 417 was split off in 1950, and the other area codes followed more than 50 years later.
