The Gun Suicide Prevention Act of 2025 aims to reduce the risk of suicide by ensuring that firearms sold in the United States carry a label with important mental health resources. The primary objective is to provide immediate help to individuals who may be struggling with suicidal thoughts by making the National Suicide Prevention Lifeline number readily available. The key provision of this legislation mandates that all firearms sold must have a label that includes the National Suicide Prevention Lifeline number, which is 988, along with the full toll-free number.
