1-800-273-TALK (8255) probably might be the most important phone eleven-digit phone number to exist in North America. The National Suicide Prevention Lifeline links callers to one of more than 200 groups and call centers run by the likes of The Samaritans and helps get them through some of their lowest moments. Mental health advocates have been pushing to get the service onto a shortcode for a long time, though, and we're only now seeing the fruits of years of work to bring the Lifeline to 988.
The FCC first proposed using 988 as a dedicated number for the National Suicide Prevention Lifeline back in August of 2019. T-Mobile was the first carrier to support the connection, followed by Verizon and AT&T.
