What this tool does
City to county, instantly
Type a city or town name and it tells you which county it sits in, which is the field legal and government forms always ask for.
Narrow it down by state
Plenty of city names repeat across the country, so adding the state resolves a Springfield or a Columbus to the right one.

The lookup table is held in the page, so nothing you type is uploaded and it works with no connection.
Frequently asked questions
Why does my city show up in multiple states?
Many city names are shared across states - there are 34 places named "Springfield" in the US alone. Type the state abbreviation or name alongside the city to get the right result.
What is a county-equivalent?
Louisiana uses "parishes" instead of counties. Alaska uses "boroughs" and "census areas." Washington D.C. is a federal district. Virginia has independent cities not part of any county. This tool labels all of them correctly.
Why do I need a county for a form?
Many US legal and government documents - property deeds, marriage licences, probate filings, court documents, tax assessor forms, voter registration, and more - require the county name because jurisdiction and record-keeping in the US is organised at county level.
Is my data uploaded anywhere?
No. The city-to-county database is built into this page. Everything runs offline in your browser and nothing is sent to a server.
