Modeled after 911, the new three-digit 988 Suicide & Crisis Lifeline is designed to be a memorable and quick number that connects people who are suicidal or in any other mental health crisis to a trained mental health professional. People can call or text this number. The National Suicide Prevention Lifeline’s 10-digit number — 1-800-273-8255 — will remain active, but calls will be routed to 988.
