Step 1: Understand the Basics of Zip Codes and Counties
Before we dive into the process of finding a county by zip code, it's essential to understand the basics of how zip codes and counties work. A zip code is a five-digit code assigned to a specific geographic area by the United States Postal Service (USPS). Zip codes are used to facilitate mail sorting and delivery, and they can range from a single building to a large geographic area.
Counties, on the other hand, are administrative divisions of a state or territory. They are typically larger than zip codes and can encompass multiple zip codes within their boundaries. Counties are responsible for providing various public services, such as law enforcement, healthcare, and education.
How Zip Codes Relate to Counties
Zip codes and counties have a complex relationship. A single zip code can span multiple counties, while a single county can have multiple zip codes within its boundaries. This can make finding a county by zip code challenging, but there are tools and resources available to help.

Step 2: Use Online Tools to Find a County by Zip Code
