- This is in accordance with FCC Mandate to allow dialing of Suicide Prevention hotline 3-digit code 988
On July 16, 2020, the FCC adopted an Order (FCC 20-100) approving the designation of 988 as
the 3-digit abbreviated dialing code for the national suicide prevention and mental health crisis
hotline, requiring all telecommunications carriers, interconnected Voice over Internet Protocol
(VoIP) providers, and one-way VoIP providers (covered providers) to make any network
changes necessary to ensure that users can dial 988 to reach the existing National Suicide
Prevention Lifeline: 1-800-273-8255 / 1-800-273 (TALK) by July 16, 2022.
- This also adds support for 3-digit code 933 to be used by 911 services and provides the ability to receive the exact information that would be delivered to 911 operators when you dial 911
Accidentally dialing 988 or 933, even if it was dialed incorrectly, will route the call immediately to their respective North America Numbering Plan approved destination.
The Order requires covered providers to implement mandatory 10-digit dialing in NPAs that use both 7-
digit dialing, 933, and 988 as an NXX.
