City and State Lookup

Each address is associated with a specific county and ZIP Code. With the help of an address validation service provider, you can easily determine the county of a given address by knowing its ZIP Code or city.

However, it is essential to note that cities and ZIP Codes can often span multiple counties and even state lines. Some cities may extend into five different counties, and approximately 20% of ZIP Codes cross county boundaries. Consequently, when using our tool, entering a city or ZIP Code might yield information for multiple counties.
