For the most accurate results, input your full street address, city and state, like this:
123 Main Street, Anytown, PA
If this doesn’t work, or you don’t feel like all that typing, you can input your zip code – either at the end of your address, like you normally would, or all by itself. You may get incorrect information if you’re searching with a zip code. This is not a fault of the locator tool, but has to do with the nature of zip codes and geolocation.
