New Area Code To Be Introduced To Parts Of Missouri

A new area code is coming to Missouri.

The North American Numbering Plan Administrator has announced that a new 235 area code will join the current 573 area code in Missouri in an effort to ensure that all residential and business customers have sufficient supplies of telephone numbers to serve that region.

The action is being take to meet the increasing demand for residential and business telephone numbers.

In February, NANPA notified the Public Service Commission Staff of the need for telephone number relief in the 573 area code. NANPA indicated the 573 area code will exhaust its available supply of telephone numbers during the first quarter of 2025.

In April, the Missouri Public Service Commission issued an order directing NANPA to proceed with an overlay plan.

Telephone numbers will not change for any existing customers but new customers may be provided with telephone numbers containing the new 235 area code.

The price of a call, coverage area, or other rates and services will not change due to the overlay.

What is a local call now will remain a local call.

Customers in the overlay region must dial 10 digits for local calls.

The 573 area code serves communities such as, but not limited to, Jefferson City, Columbia, Rolla, Cape Girardeau, Poplar Bluff, Sikeston, Mexico, Hannibal, Camdenton, Waynesville,
Farmington and Caruthersville.
