Your extended ZIP code, also known as ZIP+4, is a nine-digit code that the United States Postal Service (USPS) uses to improve mail delivery efficiency.

What & Why of ZIP+4 Codes

What is a ZIP+4 Code?

The ZIP+4 code was introduced by the USPS in 1983 to streamline mail sorting and delivery. The four-digit add-on identifies a specific geographic segment within the five-digit ZIP code area, such as a city block, a building, or even a group of post office boxes. For example, "12345-6789" is a ZIP+4 code, where "12345" is the regular ZIP code and "6789" is the extended portion.

Why are ZIP+4 Codes Important?

• Improved Accuracy: ZIP+4 codes help the USPS sort mail more precisely, reducing the chances of misdirected mail.
• Faster Delivery: By pinpointing exact delivery locations, the ZIP+4 code can speed up the mail delivery process.
• Automation Compatibility: ZIP+4 codes are essential for automated mail processing systems, which read and sort mail electronically.
• Business Benefits: Businesses use ZIP+4 codes for targeted mailing campaigns, address verification, and to qualify for postal discounts.

Potential Risks of Not Using ZIP+4 Codes

• Delivery Delays: Mail without a ZIP+4 code may take longer to arrive, especially in densely populated areas.
