HeartLine, Inc. has been serving Oklahoma since 1971 and provides suicide prevention outreach programs, compassionate listening, information and referral services, and crisis intervention services. Call specialists are available around the clock answering HeartLine’s various helplines, including: 2-1-1, 848-CARE, the Oklahoma Problem Gambling Helpline 1-800-522-4700, and two national suicide prevention lines, 1-800-SUICIDE and 1-800-273-TALK.
HeartLine staffs the state 2-1-1 helpline in 40 counties in central and western Oklahoma, the two National Suicide Prevention Lifelines in 76 Oklahoma counties, and the Oklahoma Problem Gambling Helpline for the entire state.  In 2012, HeartLine fielded a record 200,935 calls for assistance.
HeartLine’s roots stem from the LifeLine telephone ministry, which originated in Sydney, Australia, in 1963 and grew to a worldwide movement by 1966. In 1967, the program arrived in the United States under the name CONTACT. By the mid-seventies, CONTACT centers were the largest provider of telephone helpline and crisis intervention services in the country.
In 1971, through the hard work and dedication of the mental health and faith communities of central Oklahoma, the Oklahoma City CONTACT Center was opened. In its first year, 100 volunteers were trained, and 8,200 calls were answered.
On January 1st, 2005, the organization was renamed HeartLine and charged with a new, broader mission: Connecting Oklahomans with help, hope, and information 24 hours a day. Today, HeartLine has a service area of over 2.3 million people in  Oklahoma through its various programs and services and is a trusted community partner in information referral and crisis intervention.
On July 1, 2009, HeartLine added the Oklahoma Problem Gambling Helpline to its services. In partnership with the Oklahoma Association for Problem and Compulsive Gambling, HeartLine brings those addicted to gambling and their families help, hope and information through a call to the 1-800-522-4700 helpline. HeartLine administers the Problem and Compulsive Gambling Helpline for all of Oklahoma.
In 2011, HeartLine was accredited through the Alliance for Information & Referral Systems (AIRS).   AIRS is a professional association for information and referral organizations which stipulates 27 best practice standards and assesses more than 200 distinct operational components for accreditation.  The standards address all aspects of the agency, including service delivery, resource database, reports and measures, cooperative relationships, organizational requirements, and disaster preparedness.
