The largest cities in Missouri include St. Louis (pop. 2,024,074), Kansas City (pop. 1,636,715), Springfield (pop. 288,090), Columbia (pop. 141,645) and Independence (pop. 116,672) . Missouri has 115 counties spread across its territory. Each area code in MO covers a geographic region of the state, with some areas using overlay codes that share the same geographic territory as an existing area code.
When calling a Missouri phone number from outside the area code, you must dial the full 10-digit number: the 3-digit area code followed by the 7-digit local number. Many parts of Missouri now require 10-digit dialing even for local calls due to overlay area codes and the nationwide 988 Suicide & Crisis Lifeline implementation.
