Your ZIP is not your county
ZIP codes are mail routes. Counties are governments. The two were drawn for different jobs, so a ZIP can sit in one county, straddle two, or spread over six. Most of the time the ZIP points to the right county: 90210 is all Los Angeles County, 60614 is all Cook County. Near a county line, it can’t.
- For anything official, use the exact spot. Taxes, voting and jury duty follow the county line at your address, not your ZIP. Pin your spot or type your address.
- The card tells you how close the line is. If it’s a few hundred feet away, double-check with your county’s property records.
- Need a whole list? Paste many ZIPs into county by ZIP code and download the counties as CSV.
County borders come from the Census Bureau’s TIGER files. ZIP-to-county shares come from the Census 2020 ZIP Code Tabulation Area to county relationship file.

Questions people actually ask
What county am I in right now?
Tap “Pin my exact spot” and allow location access. The county you’re standing in lights up with a blue dashed border, and the card tells you how far the county line is. Before you tap, the page shows the county of the ZIP your internet connection points to, which can be off near a border.
Can a ZIP code be in more than one county?
Yes, often. 10,186 of the 33,791 ZIP code areas, about 30%, reach into more than one county. 2,546 touch three or more, and four touch six, like 39573 around Perkinston, Mississippi. 137 even cross a state line. That’s why a ZIP alone can’t always tell you your county.
How many counties are in the US?
There are 3,143 counties and county equivalents in the 50 states and DC in the 2020 Census. They include Louisiana’s 64 parishes, Alaska’s boroughs and census areas, and 41 independent cities, 38 of them in Virginia plus Baltimore, St. Louis and Carson City. Puerto Rico adds 78 municipios.
My city is in two counties. Which one am I in?
It depends on your exact spot. Big cities often spill over county lines: Houston reaches into Harris, Fort Bend and Montgomery counties, and New York City is five counties, one per borough. Pin your spot or type your street address for the answer at your door.
Why does Connecticut show a “planning region” instead of a county?
Connecticut has had no county governments since 1960, and in 2022 the Census Bureau replaced its eight old counties with nine planning regions. Lookups by exact spot use the current Census geography, so they return the planning region. The ZIP lists here still use the 2020 county lines.
How do I find my county by ZIP code?
Type the ZIP in the search box. If the ZIP sits in one county, that’s your answer. If it spans several, the card lists each with its share of land, and you need your exact spot or street address to know which side you’re on. For many ZIPs at once, use county by ZIP code.
How do I find what county an address is in?
Type the full street address with city and state, like “350 5th Ave, New York, NY”. The Census Bureau geocoder places it on the map and returns the county at that exact point, even near a county line.
Is a parish or a borough the same as a county?
For lookups, yes. Louisiana calls its counties parishes, and Alaska uses boroughs and census areas. The Census Bureau treats them all as county equivalents, and so does this page.
Does this site store my location?
No. Your coordinates are used once to look up the county you’re in, then dropped. They aren’t saved, logged or shared.
