US Address Checker & GPS Finder: Verify & Geocode

Check US addresses in bulk. Paste one address or thousands and get one clean row per address: is it real, the cleaned up official version, and its exact GPS location for maps. Plus the county, official city, congressional district and census tract when you want them.

Built for real estate and logistics teams, mailing list owners, market researchers and app builders. Built on the official US Census Bureau geocoder, so there is no API key, no signup and no per-seat license.

What you get for each address

• Found or not: instantly flags addresses that do not exist.
• The cleaned official version: "1600 pennsylvania ave washington dc" becomes "1600 PENNSYLVANIA AVE NW, WASHINGTON, DC, 20500".
• GPS location (latitude, longitude) ready for maps and routing.
• Area info (on by default): county with FIPS code, official city or town, congressional district and census tract, the fields analysts join demographics on.

Frequently asked questions

Does it work outside the US? No, US addresses only (including DC and Puerto Rico). That is what the Census geocoder covers.

How accurate is it? It matches against the Census Bureau's national address database, the same data behind official statistics. Addresses it cannot match are flagged rather than guessed.

What is a census tract and why would I care? It is the small area code that all US demographic data is published against. With it you can join income, population and housing stats onto your address list.
