Frequently Asked Questions
How do I find out what county an address is in?
Our tool instantly identifies the correct county for any U.S. address. Just enter the street address (and zip code if needed) in our live demo, and the county will appear in seconds — no maps or guessing required.
Can I look up which municipality issues permits for an address?
Absolutely — our lookup tool displays the proper municipality responsible for permits and licensing (e.g., city, township). Just input the address and zip code into our live demo page to see it in action.
What’s the difference between city and county permits?
City permits apply when an address lies within a city or town boundary. In unincorporated areas, you’ll need county permits instead. Our tool automatically distinguishes between the two — displaying the city name if inside one or showing ‘Unincorporated’ and the relevant county if not.
How can contractors quickly determine county and city jurisdiction by address?
With our Municipality & County Lookup Tool, contractors can instantly identify jurisdiction by address — no GIS training required. Simply type in the address in the demo, and get county and municipality details in seconds.
