Certification of Membership for Congregations

All Unitarian Universalist Association (UUA) member congregations are required to complete the Certification of Membership report by the annual February 1 deadline. Congregations that fail to file this annual report will not be eligible to have voting delegates at the upcoming General Assembly. 

Updating Membership List & Staff Information

Congregations must manage their list of member names and addresses (for delivery of UU World magazine) and staff/leader information (which appears in the online Directory) throughout the year using the account system.

Individuals who have already been authorized as data updaters for the system may log in to their personal accounts to make these changes. First-time users must begin by completing the registration process. Note: The process for registering a new account and becoming authorized in the Unitarian Universalist Association's (UUA's) system as a Data Updater may take a day or two.

General Information

We offer resources to member congregations, related organizations, districts, and UUA committees. We collect data from UUA member congregations including the mailing addresses of its members (for sending UU World magazine) and the statistical and membership totals supplied by congregations annually during Certification of Membership.

Data Services also provides mailing lists and data to any member congregation, district or related organization for, but not limited to, the promotion of their sponsored events and selected materials, the cultivation of relationships with their constituencies and the calculation of growth analysis.


The Office of Data Services collects data on ministers, districts, congregation members, UU World subscribers, congregation staff, and elected officers. This data is vital—it is published in the Unitarian Universalist Association Directory and analyzed at the district level. Only membership and religious education enrollment totals for all Unitarian Universalist congregations are released to the media; no individual congregation's data is made public.
