MEDIA REMINDER:
10-Digit Local Dialing to Begin February 24 for 573 Area Code Customers
New 235 Area Code Overlay Begins In March
JEFFERSON CITY--- The Missouri Public Service Commission, the North American Numbering Plan Administrator (NANPA) and the telecommunications industry remind customers to continue preparing for
10-digit local dialing and the introduction of the
new 235 area code in the current 573 area code in Missouri.
The 235 area code will be added as an overlay to the 573 region. An overlay is the addition of another area code (235) to the same geographic region served by an existing area code (573).
An overlay does not require customers to change their existing area code, but does require customers to dial the area code to complete 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.
“The 573 area code is not going away,” said Missouri Public Service Commission Chair Kayla Hahn. “If you have a telephone number with the 573 area code, you will not lose that number and you will not have to change your telephone number. An overlay will alleviate the exhaustion of available telephone numbers in the 573 area code, and it is a more efficient and less disruptive way to accomplish that.”
A six-month permissive dialing period started on
August 26, 2023, to give consumers adequate time to adjust to the dialing changes. During that time, local calls can be made with either 7 or 10 digits, and all calls that are local will continue to be local even though you dial 10 digits.
Beginning
February 24, 2024, all local calls made within the 573 area code must be placed using 10 digits (area code + the 7-digit telephone number).
On and after February 24, 2024, any calls placed using just 7 digits will not be completed.
Starting on
March 24, 2024, new telephone lines or services may be assigned numbers using the new 235 area code.
Key facts for consumers to know about the upcoming 573/235 area code overlay are:
- Your current telephone number, including current area code, will not change.
- What is a local call now will remain a local call.
- If you seek new phone service on and after March 24, 2024, you may be assigned a phone number with the 235 area code.
- You will need to dial the area code + telephone number for all local calls, including calls within the same area code.
- You will continue to dial 1 + area code + telephone number for all long distance calls.
- The price of a call, coverage area, or other rates and services will not change due to the overlay.
- You can still dial just three digits to reach 911 and 988. You can also dial three digits to reach 211, 311, 511, 611, 711 and 811 where available.
Remember to identify your telephone number as a 10-digit number and include the area code when giving the number to friends, family, business associates and customers.
Customers should ensure all services, automatic dialing equipment, applications, software, or other types of equipment are reprogrammed to dial 10 digits if they are programmed to dial just 7 digits and recognize the new 235 area code as a valid area code. Examples include life-safety systems, fax machines, Internet dial-up numbers, gates, ankle monitors, speed dialers, mobile phone contact lists, call forwarding settings, voicemail services, and similar functions. Be sure to check your business stationery, advertising materials, personal checks, and your personal or pet ID tags to ensure the area code is included in your telephone number.
Important safety and security equipment, such as medical alert devices, and alarm and security systems must be programmed to use 10-digit dialing. Many systems operate on 10-digit dialing by default, but some older equipment may still use 7 digits.
Please contact your medical alert or security provider if you are not sure whether your equipment needs to be reprogrammed to accommodate the upcoming change to 10-digit local dialing. Any needed reprogramming of alarm and home security equipment must be completed by
February 24, 2024.
Remember all local calls must be programmed using 10 digits and add ‘1’ for all long distance calls.
