816 area code changes to 975 for new customers/ Adrian, Drexel, Holden.

JEFFERSON CITY—The Missouri Public Service Commission continues to work with the

North American Numbering Plan Administrator (NANPA) and the telecommunications industry on

implementation of an overlay plan and the introduction of a new area code in the 816 area code

region in Missouri. The new area code will be 975. All existing 816 area code customers will

retain their current area code in the overlay area and their telephone numbers will not be


The 816 area code serves communities such as, but not limited to, Kansas City, St. Joseph,

Savannah, Richmond, Maysville, Odessa, Adrian, Holden, Lawson and Drexel.

The Missouri Public Service Commission originally adopted an overlay plan for the 816 and 314 area codes in an order issued on October 24, 2000. However, on September 25, 2001, the Commission delayed indefinitely the implementation of the area code overlay relief plans in order to allow time to test the effectiveness of telephone number conservation efforts.

“Telephone number conservation efforts were successful and we were able to delay the area code overlay implementation plan for the 816 area code for more than 21 years,” said Public Service Commission Chairman Scott Rupp. “The exhaustion of available telephone numbers led to an overlay plan and the introduction of the new 557 area code in the 314 area code region in August of

last year.”

NANPA has indicated to the Public Service Commission that telephone numbering in the 816

area code is again nearing exhaustion. NANPA projects the 816 area code will exhaust in the second

quarter of 2024.

August 8, 2023 is the earliest date companies can request telephone numbers with the 975 area code and October 13, 2023 is the earliest date the 975 area code will be activated. Both of those dates could be pushed back depending on when telephone numbers actually exhaust in the 816

area code. The 975 area code will co-exist everywhere in this region with the 816 area code. All local calls within this region must be dialed using ten digits rather than seven digits. The 816 area code,along with many other area codes throughout the country, were required to eliminate seven digit local dialing in July of 2022 in order to accommodate the new 988 abbreviated dialing code for the national

suicide prevention and mental health crisis hotline.
