A
state is a geographical area within a country that has its own government and laws. It's often used to describe the level of administration below the national level.

    In the United States, for example, there are 50 states, each with its unique characteristics and features. These states have their own capitals, governments, and administrative systems.

    A zip code is a series of numbers assigned to a specific geographic area within a state or country. It's used primarily for postal purposes, helping mail carriers deliver packages efficiently.

    Zip codes can vary in length depending on the location, but they usually consist of five digits. Some areas may have additional four-digit extensions known as ZIP+4 codes, which provide more precise delivery information.

    Country refers to a large area with defined borders and a distinct population. It's often considered the highest level of administrative division.
