Service Announcement: 10-Digit Local Dialing for the Missouri 314 Area Code

Submitted by Ann Hogan

Ten-digit local dialing will soon be required for all calls in the 314 area code. The Danforth campus phone system already supports ten-digit local dialing. Five-digit dialing will remain in effect for internal calls on the Danforth campus phone system.

The Federal Communications Commission has approved using 988 as the three-digit abbreviated dialing code for the National Suicide Prevention and Mental Health Crises Hotline (currently 1-800-273-8255/TALK), starting July 16, 2022. As part of the designation of 988 as the three-digit abbreviated dialing code, 10-digit local dialing has gone into effect for the 314 area code.
