Overview
What is USA Geocoding?
Every US address resolved to a precise rooftop coordinate and its exact tax jurisdiction — fused from open address data, OpenStreetMap, US Census geographies, and state, municipal, and special-district shape files, corrected continuously and refreshed weekly.
Forward and reverse geocoding purpose-built for tax, not just maps. Most geocoders stop at a single data source and a ZIP-code approximation. GoodVat fuses multiple independent layers — OpenAddresses, OpenStreetMap, US Census TIGER/Line, and state, county, municipal, and special-district boundary files — cross-referencing every one to resolve a true rooftop point and the exact jurisdiction stack it sits inside. The result is continuously corrected against real-world discrepancies and re-ingested every week, so annexations, new special districts, and boundary changes never leave you calculating tax against a stale map.
How it works
Six data sources, one answer
OpenAddresses, OpenStreetMap, US Census TIGER/Line, state parcel data, municipal boundary files, and special-district shapefiles are cross-referenced and reconciled into a single rooftop point — not just whichever source responded first.
Corrected, not just collected
Conflicts between sources — mis-drawn boundaries, stale annexations, duplicate parcels — are continuously reviewed and fixed before they ever reach your app.
Refreshed weekly
Jurisdiction boundaries change constantly: annexations, new special districts, redrawn municipal lines. GoodVat re-ingests and re-reconciles every week so your results never go stale.
Jurisdiction resolution
Every result returns the exact state, county, city, and special districts an address belongs to — ready to feed straight into tax calculation.
