Firstlogic Team
ZIP+4 Codes are an extension of the traditional 5-digit ZIP codes used by the USPS, providing a more precise way to identify specific groups of delivery points within a given ZIP code. Each ZIP+4 code can represent a range of delivery points, such as a block of apartments or a group of businesses, as well as individual delivery points.
Looking up ZIP+4 codes can be easy with the right tools. The USPS provides a free ZIP Code lookup service on their website that allows users to find ZIP+4 codes for specific addresses or ranges of addresses. If you find the USPS ZIP Code lookup service doesn’t meet your needs, Firstlogic offers an easy-to-use lookup tool below that provides accurate and up-to-date information.

What are ZIP+4 Codes?
ZIP+4 codes, also known as Plus-Four codes, ZIP code extensions, 9 digit ZIP codes, extended ZIP codes, or full ZIP codes, are four-digit codes that are appended to the traditional five-digit USPS ZIP codes. When used in conjunction with the full ZIP code, the additional four digits allow for more accurate and efficient mail delivery.
Each ZIP+4 code represents a specific delivery route, which typically includes 10 to 20 homes or locations. These routes are not permanent and can change regularly, making the last four digits of ZIP codes more volatile than the first five digits. Factors such as the quantity of postal employees, new construction, and remapping of delivery areas can all contribute to changes in ZIP+4 codes.
Due to the dynamic nature of ZIP+4 codes, it’s important to keep address lists and mailing labels up to date with the most current ZIP+4 codes available. Using an accurate and up-to-date ZIP+4 code lookup tool, such as the ones mentioned earlier in this article, can help ensure that your mail is delivered to the correct location in a timely and efficient manner.
