This is a list of telephone area codes in the state of Missouri. The area codes are allocated within the North American Numbering Plan (NANP).
The two original area codes for Missouri in 1947 were 314 and 816. Area code 417 was split off from 816 in 1950, and the other area codes followed more than 40 years later, due to the proliferation of Cellular Phones and Pagers.
