01 — Missouri at a Glance

Missouri, by the numbers.

Missouri began in 1947 with two codes: 314 for eastern Missouri (St. Louis) and 816 for western Missouri (Kansas City). In 1951, 417 split off for Springfield and the Ozarks.

That three-code map held for decades. In 1997, 660 split from 816 to cover northern Missouri outside the Kansas City metro.

St. Louis's outer suburbs got their own code, 636, split from 314 in 1999. 417 remains unsplit to this day.

Did you know?

Area code 417, created in 1951 to serve Springfield and the Ozarks, has never been split — one of the longest-standing untouched boundaries on Missouri's numbering map.
