Unit 356 supervises and promotes sanctioned bridge in Southern Arizona. It is a member of District 17 of the American Contract Bridge League, the governing body for contract bridge in the United States, Mexico, Bermuda and Canada.

District 17 is made up of over 22 units located in Arizona, Colorado, New Mexico, Southern Nevada, Eastern Utah, Western Texas and Wyoming. 

Unit 356 partners with District 17 to provide regional tournaments, special games and grass roots events and electronically communicates to its membership via the District 17 Bridge Buzz and the ScoreCard. 

Comprised of approximately 1,100 members, Unit 356 is managed by a Board of Directors elected from the membership in which it serves.

The Unit 356 board seeks to preserve and foster community through effective and consistent communication and by listening and responding to the bridge-related needs of both clubs and players. Its goal is to provide well-organized, hospitality-driven regionals, sectionals, games and events that meet the social, recreational and competitive needs of its players. Fiscal responsibility, transparency and upholding the highest standards of conduct and ethics are key.
