Our church is looking for guidance on retaining and/or archiving our records. What do you suggest?
The Research and Data team does not provide direct assistance in this area. However, the Office of General Counsel has some information and a sample records retention policy for conferences that also applies to churches.
Can I call you and get a minister’s contact information?
We do not share contact information directly, but such information can be found in the Yearbook (available for order from UCC Resources) and on Access UCC.
I’m looking for historic church documents like wedding or baptism certificates. Can you help locate the information?
Unfortunately, we do not have access to detailed records of this kind, but they may be available at the congregation where the services took place. If the congregation is now closed, you may have luck contacting the conference office where the congregation is/was located.
Can you help me find a UCC congregation in my area?
Yes! Please visit our Find a Church page, which displays a searchable map of UCC congregations across the country.
How do I learn about the community around my church?
To learn more about your community, we recommend the Community Profile Builder tool maintained by the Association of Religion Data Archives (ARDA). This free resource pulls together demographic data as well as materials from the US Religion Census to create a profile for regions across the US.
