The three-digit 988 dialing code, which provides direct access to the National Suicide Prevention and Mental Health Crisis hotline, will be effective on July 16, 2022. All telecommunications carriers must route 988 calls to the existing National Suicide Prevention Lifeline: 1-800-273-8255 (1-800-273-TALK). To accommodate 988 within all networks, carriers must implement mandatory 10-digit dialing in the number plan areas (NPAs) that use seven-digit dialing and 988 as an NXX.

The NPAs required to transition to 10-digit dialing are as follows:

All impacted service providers are required to provide a milestone completion status to the North American Numbering Plan (NANPA). Carriers must notify NANPA by email at 988@nanpa.com and include the relevant provider name, OCN(s), state(s), and NPA(s) in the email. In addition, carriers must provide carrier contact information to NANPA for troubleshooting of any permissive 10-digit dialing issues.

988/10DD Milestones to Report to NANPA:

Milestone Service Provider Required Action Due Date
8 Issue first customer notification. Carriers using bill messages may want to have these run multiple months rather than just one month to help ensure customers are aware of the upcoming dialing changes. 3/25/2021
11 Provide carrier contact information to NANPA for troubleshooting of any permissive 10-digit dialing issues. Include in the email: state(s), provider name, primary contact, telephone number(s), hours of operation, backup contact/escalations, email address, and telephone number(s). 4/10/2021
15 Carrier deadline to have permissive 10-digit dialing opened in their networks (carriers can implement this any time up to this deadline, no need to wait until the night before to implement). 4/24/2021
23 Issue second customer notification. Carriers using bill messages may want to have these run multiple months rather than just one month to help ensure customers are aware of the upcoming dialing changes. 9/24/2021
24 Carriers should be signaling/sending 10 digits of the called to party for all calls terminating in all end offices and access tandems in the area code. 9/24/2021
33 Carrier deadline to enforce mandatory 10-digit dialing (carriers have the interval between the mandatory 10DD effective date above and this deadline to remove 7DD and enforce 10DD on the schedule that works best for them). 7/15/2022
