GeoFlow vs Geocodio: Free County & District Appends from Official Data

Geocodio charges per lookup for appending county, congressional and state legislative districts. GeoFlow does the same appends from the free Census Geocoder — free up to 100 addresses per run.

Comparison

Where the underlying data is public domain anyway (county, districts, coordinates), the free official API is sufficient — you pay for volume, not for data. GeoFlow keeps that volume cheap: 4 addresses/second, 100 per run free, $9 one-time for 1,000.

When Geocodio still makes sense

• You need geocoding outside the U.S.
• You need phone/carrier appends or specialized data teams GeoFlow does not offer.

FAQ

Is the data the same?

For county/congressional/SLD layers, GeoFlow uses the U.S. Census Bureau itself — the same source.
