Find any 235- phone number in Missouri

The 235 area code is located within Missouri and is part of the North American Numbering Plan (NANP). The NANP is a system that is used by Canada, the United States, and some Caribbean countries that assigns a unique three-digit area code to each geographic region.

In the case of the 235 area code, it is one of nine area codes used in Missouri. It is primarily used as an overlay for the 314 area code and covers the greater St. Louis metropolitan area including St. 21 counties. It was created in August, 2017 to add capacity and reduce the strain on the 314 area code’s limited resources. The 235 area code is reserved by the North American Numbering Plan Administration for future expansion, if needed.
