Catholic Parish Dataset

A free, public registry of U.S. Catholic parishes and dioceses, with stable IDs you can build on.

We're still populating this registry. Each entry carries a data-quality score showing how complete and well-sourced it is today; many are sparse for now, and the scores climb as we verify and enrich the data.

Built from public data

Google Places + direct website crawls + diocesan websites. No paid databases. No exclusive licenses.

Permanent IDs

Every parish has a permanent identifier. Even if the parish closes, merges, or renames, the ID stays the same.

Owned by parishes

Any parish can report an error from any page, and we review it within 48 hours.
