About 573 Area Code
Area code 573 serves Columbia and most of central and southeastern Missouri outside the St. Louis metro area. Created on January 7, 1996 as a split from the original 314 area code, 573 covers major population centers including Columbia, Jefferson City, Cape Girardeau, Rolla, Hannibal, Poplar Bluff and Sikeston, extending across Boone, Cole, Cape Girardeau, Phelps and dozens of other counties. The code supports local voice and SMS-capable numbers used by businesses, government agencies, educational institutions and healthcare organizations across university towns, the state capital, and rural communities throughout central Missouri.
The 573 region is anchored by university-driven demand from the University of Missouri in Columbia and Missouri S&T in Rolla, state government operations in Jefferson City, healthcare systems, insurance companies like State Farm and Shelter Insurance, and manufacturing operations including 3M, Cargill and Kraft Foods. Local businesses use 573 numbers for student services, constituent communications, appointment confirmations, policy inquiries, customer support and distribution coordination. These practical applications consistently deliver higher answer rates than toll-free alternatives because they signal genuine local connections and meet regional expectations.
FoneSwift lists live 573 inventory and capabilities on this page. Search numbers to see which ones support Voice, SMS and MMS. Area code availability changes over time; if a local 573 number isn't immediately available, similar results from the overlay 235 or nearby NPAs (e.g., 314, 417, 660) may still deliver strong regional presence for Missouri-focused audiences.
If your business targets Columbia or central Missouri, publish numbers in both local and E.164 formats (e.g., (573) 555-1234 and +1 573 555 1234) and register messaging traffic if you plan A2P campaigns. For porting, see our porting guide. Many businesses maintain their original numbers through porting to preserve customer recognition while upgrading infrastructure. Note that 10-digit dialing became mandatory in February 2024 following the introduction of the 235 overlay.

How Does Local 573 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages. When you use a 573 number in Columbia and Missouri, the digits signal the international gateway, the geographic region, the local exchange and the specific subscriber, so calls reach the right destination quickly and reliably.
The typical parts of a United States local number are:
- Country code (+1): identifies United States for international routing.
- Area code (573): directs the call to the Columbia / Missouri region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
Example formats:
| International Format (E.164) | +1 573 555 1234 |
| Local Format (National) | (573) 555-1234 |
