Zovo Address Geocoder

US address lists to geography

Geocode US address lists with coordinates, counties, tracts and district columns in downloadable Excel and CSV files.

What it does

Preserve input rows and columns in files
Filter and sort matches
Coordinates and tracts for up to 1,000 rows; districts for up to 100

Try asking

“Census tract lookup for 350 Fifth Ave, New York, NY 10118”

“Congressional district by address: 1437 Bannock St, Denver, CO 80202”

Limitations

US Census address ranges only: 50 states, DC, Puerto Rico and island areas.
Interpolated street points may be tens of meters from a building. PO boxes, rural routes and new streets may not match.
Check non-exact matches. District boundaries do not identify elected representatives.
A 1,000-row list may take about 30 seconds, or longer if the service is slow.
