Certification of Membership for UUA Congregations - Due Monday, Feb. 5, 2024

All UUA member congregations are required to submit their annual Certification of Membership report online by the end of business on Monday, February 5, 2024. You may file the report online, and review the Certification Worksheet for congregations, when you log in to the congregation's Data Services account online.

For more information about congregation certification, please contact Data Services at, (617) 948-4654.

For information about delegate credentialing for General Assembly, please contact the General Assembly Office at, or (617) 948-4209.

Updating Membership List & Staff Names

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

Authorized users at congregations may log in to the congregation's shared account using the 4-digit ID number for the congregation as the username, and the case-sensitive account password. (If you previously registered your own username for MyUUA access, you may still log in to the account with your personal username too!)

Data Requests

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.

UUA committees, UUA affiliates, and other related organizations can order mailing lists and other information at the Data Services Request Center.


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.
