The 235 area code is a Missouri telephone area code that covers the same territory as 573, including Columbia, Jefferson City, Cape Girardeau, Rolla, Hannibal, and Poplar Bluff. It launched on March 24, 2024, as an overlay code (not a split), meaning both 573 and 235 numbers now serve the same region side by side. It operates in the Central Time Zone and is not a toll-free or scam-only prefix.
What Is the 235 Area Code?
