A collaborative group of local comprehensive and specialized information and referral providers who have agreed to coordinate information and referral service delivery to provide seamless access to information about community resources via the three digit number assigned for this purpose, 211. Depending on the size and nature of the community, 211 systems may consist of only a few organizations that provide information and referral or may include a diverse array of organizations that furnish some type of I&R. Some of these organizations may supply a very specialized type of I&R service (e.g., for people with disabilities or older adults), while others may provide a comprehensive range of assistance. The coordination of all I&R services and programs within a community and, where relevant, beyond, constitutes the 211 system.
