UNITS are not subsidiary to the districts, but rather are the governing basis for the ACBL.
​
There are 24 Units within the geography of District 19. Smaller units have as few as twenty-four members, and the largest units are Seattle and Vancouver.

When you join the ACBL you are automatically a member of your geographical district and unit.

Units are directly responsible for Sectional Tournaments, Unit Games, Unit Finals of multi-level events (GNT, NAP, CNTC, and CWTCC), Membership and other issues relating to local government and bridge organization.

The following bridge clubs are within the Okanagan Unit 571 - Kamloops, Kelowna, Penticton, Vernon, West Kelowna ​
