Understanding Your Code Postal in the United States
Your code postal, also known as ZIP code, is a critical component of your address in the United States. It’s not just a series of numbers; it’s a gateway to a wealth of information about your location. Let’s delve into what a code postal is, how it’s structured, and its various uses.
What is a Code Postal?
A code postal is a five-digit number that uniquely identifies a geographic area within the United States. It’s used by the United States Postal Service (USPS) to sort and deliver mail efficiently. The format is straightforward: the first three digits represent the state, the fourth digit is a district within the state, and the last two digits are a specific delivery area within the district.
Structure of a Code Postal
Let’s break down the structure of a typical code postal:
| Part | Example | Description |
|---|---|---|
| First 3 Digits | 902 | Represents the state. For example, 902 is for California. |
| Fourth Digit | 1 | Represents a district within the state. This can vary widely, from a single ZIP code for a large city to multiple ZIP codes for a smaller town. |
| Last 2 Digits | 23 | Represents a specific delivery area within the district. This is the most granular level of the ZIP code system. |
For example, the ZIP code 90210 is for Beverly Hills, California. The first three digits (902) indicate the state, the fourth digit (1) indicates the district, and the last two digits (10) indicate the specific delivery area.
Uses of Code Postal
ZIP codes are used in a variety of ways beyond just mail delivery. Here are some common uses:
