To ensure a continuing supply of new telephone numbers, the Missouri Public Service Commission has approved an all-services area code overlay for the 816 area code, which serves western Missouri including but not limited to the communities of Kansas City, Blue Springs, Plattsburg, Fillmore, Richmond, Odessa, Harrisonville, and Adrian. The new 975 area code will serve the same geographic area currently served by the existing 816 area code.
What is an area code overlay?
An overlay is the addition of another area code (975) to the same geographic region as an existing area code region (816). The overlay does not require you to change your existing area code or phone number, or how you dial your calls. You will continue to dial the area code and phone number for all local calls, as you do today, within and between the 816 and new 975 area codes.
Who will be affected and when does the new 943 area code become effective?
Beginning October 13, 2023, customers in the 816 area code overlay region may be assigned a number in the new 975 area code when they request new service or an additional line. Customers receiving a 975 area code will be required to dial the area code and phone number for all local calls, just as customers with telephone numbers from the 816 area code do today.
