The General Service Office of AA ("GSO" to most members) is located at 475 Riverside Drive in New York City. GSO serves all AA groups in the United States and Canada, and also offers services to AA overseas, especially in countries where there is no service structure. While many other countries have their own GSO's, The US/Canada General Service Office, the earliest to be established, is generally regarded as the "senior" office. It serves as a clearinghouse and exchange point for the wealth of AA experience accumulated over the years, coordinates a wide array of activities and services, and oversees publication, all translations of, and distribution of AA Conference approved literature and service materials.
