Find the county code without leaving the map
When you already know the county or can find it on the map, the next step may be the FIPS code. The app keeps those pieces together so the lookup feels like one workflow instead of two disconnected tools.
Reverse the lookup from code to county name
A common search is county FIPS to county name because the code often shows up first in a dataset or export. The app helps you confirm which county that code belongs to before you publish or act on it.
Useful for records, data cleanup, and reporting
If a spreadsheet, permit, boundary file, or work order depends on the correct county code, mistakes are costly. County Names & Lines gives you a faster way to verify the county and the code together.
Designed for practical county data checks
This is not just a long list of county FIPS codes. It is built for people who need to move from location to county to code, then trust what they found.
County questions answered
Short answers to the questions people ask before choosing a county lookup app.
What is a county FIPS code?
A county FIPS code is a numeric geographic identifier used to identify a county or county-equivalent area. A full county FIPS code combines the two-digit state code with the three-digit county code.
How do I find a county FIPS code?
Start with the county name, address, or map location, then match that county to its state and county code. Address or location lookup is safer than ZIP-only lookup when precision matters.
How do I match a FIPS code to a county name?
Read the first two digits as the state code and the last three digits as the county code within that state. Then match the combined code to the county or county equivalent in the relevant state.
