Additional county-finding websites include the U.S. Census Bureau's State & County QuickFacts page. This page can access county data based on a ZIP code, street address or place name (city or town). The National Association of Counties' webpage offers a county look-up service, with the added features of data related to each U.S. county's economy, tax rate, transportation system, municipal bonds, schools and other topics of interest to the general public.

Once a location's county has been determined, researchers can often find information about the county's state and federal electoral districts and representatives, land parcel ownership, county services and demographics. Knowing an address's county makes it easy to compare it to other locations of interest, which can be helpful to people considering relocating, opening a business or choosing a travel destination. It is not uncommon for adjacent counties to have differing laws on a variety of issues of concern to prospective residents, workers or visitors.
