Introduction

In the world of mail delivery, precision is key. While the five-digit ZIP code revolutionized mail sorting, the ZIP+4 code takes it a step further, enhancing accuracy and efficiency. This guide will walk you through everything you need to know about ZIP+4 codes, from their purpose to how to find them quickly and easily.

What & Why

The United States Postal Service (USPS) developed the ZIP+4 code system in the 1980s to improve mail delivery. It's an extended ZIP code that includes the original five digits plus four additional digits. These extra digits represent a specific segment of a street, a building, or a group of post office boxes.

What is a ZIP+4 Code?

A ZIP+4 code is a nine-digit code used by the USPS to pinpoint a more specific location within a ZIP code area. The first five digits represent the general delivery area (city or town), while the last four digits indicate a specific delivery route, building, or even a floor in a large office building. For example, in the code 90210-1234, 90210 is the general ZIP code, and 1234 identifies a particular delivery route or building within Beverly Hills, California.

Why Are ZIP+4 Codes Important?

Using the correct ZIP+4 code offers several advantages:

• Faster Delivery: Accurate codes enable automated sorting equipment to process mail more efficiently.
• Reduced Errors: They minimize the chances of mail being misdirected or delayed.
• Lower Costs: Efficient sorting reduces USPS operational costs.
• Bulk Mailing Requirements: Businesses sending large volumes of mail are often required to use ZIP+4 codes to qualify for discounted postage rates.

Benefits of Using ZIP+4 Codes

• Improved Accuracy: Minimizes errors, ensuring mail reaches the intended recipient promptly.
• Faster Delivery Times: Reduces processing and delivery times, especially for large mail volumes.
