Looking up this point in Census records…
Not in a US state, DC or Puerto Rico
The Census Geocoder covers the 50 states, DC and Puerto Rico. This point is outside that area, so there is no to show.
Not available here: county, city, ZIP code, state, school district, congressional district, township.
Still available: elevation and time zone (see below).

How it works
- Your point comes from your device's GPS, a US address (matched by the Census Geocoder), typed coordinates or a click on the map.
- The coordinates go to the Census Geocoder, which checks them against the Census Bureau's county boundaries (current vintage, as of January 1, 2026) and returns the county with its FIPS code and area.
- The same single lookup also gives the city, ZIP code area, school district, congressional district and township in the at-a-glance card.
- The map draws the county outline from Census TIGERweb, the same boundary data simplified so it loads quickly.
Counties and county equivalents
The Census Bureau counts 3,144 counties and county equivalents in the 50 states and DC. Most are called counties; the rest go by other names (Census glossary):
- Parishes in Louisiana.
- Boroughs and census areas in Alaska.
- Planning regions in Connecticut, which replaced the state's eight counties in Census data (Census county changes).
- Independent cities in Virginia, plus Baltimore, St. Louis and Carson City.
- The District of Columbia, counted as one county equivalent.
- Municipios in Puerto Rico (78).
When your point is in a county equivalent, the answer says so next to "Type".

Frequently asked questions
How does this tool find my county?
It sends the coordinates of your point to the U.S. Census Bureau Geocoder, which returns every Census area that contains it. County boundaries are the Census Bureau's as of January 1, 2026. Only the coordinates are sent, and answers are cached by coordinate for 90 days so repeat lookups are fast.
What is a county FIPS code?
A five-digit code the federal government uses for each county. The first two digits are the state and the last three are the county within that state. Denver County, Colorado, for example, is 08031.
How many counties are there in the US?
The Census Bureau's current boundaries have 3,144 counties and county equivalents in the 50 states and the District of Columbia, plus 78 municipios in Puerto Rico.
Does every state have counties?
Not under that name. Louisiana has parishes and Alaska has boroughs and census areas. In Connecticut the Census now uses nine planning regions in place of the eight former counties. Independent cities, such as those in Virginia and Baltimore, St. Louis and Carson City, are county equivalents that belong to no county.
Is my county the one in my mailing address?
Not always. Mailing city names and ZIP codes do not follow county lines, and one ZIP code can cover parts of several counties. Your county depends on where the property physically is, which is what this tool checks.
I am right on a county line. Can I trust the answer?
The answer uses the Census Bureau's full-detail boundary; only the outline on the map is simplified. The weak point is the location itself: check the accuracy shown under the GPS button, or search the exact address. For taxes, voting or legal questions, confirm with the county.
Why does it say the point is not covered?
The Census Geocoder covers the 50 states, the District of Columbia and Puerto Rico. Elsewhere, including other US territories and other countries, the tool still shows elevation and time zone but no county.
