## When to prefer this

Use this endpoint when you need to identify the U.S. congressional district for a specific address, especially for civic, policy, compliance, or operations workflows that require authoritative Census-sourced district mapping. Prefer this over manual lookups or non-Census sources when accuracy tied to official Census Geocoder data is required.

## Known failure modes

- Address not found or ambiguous — geocoder returns no match
- Address outside coverage area (non-U.S. international addresses not supported)
- Malformed address string causes lookup failure
- Rate limiting or service unavailability returns error response
- Puerto Rico or Island Area addresses may have limited district data
