Comparison

Weganar vs. the Census Geocoder

The Census Bureau's geocoder is free and authoritative, and it caps you at 10,000 addresses per batch file. Use it. When it will not scale, we return the same Census geography from rooftop and parcel points, batch 100 addresses per call with no cap on calls, and name the source of every point on the response.
