Overview

Delaware, the second smallest state in the United States, is divided into multiple ZIP codes to facilitate efficient mail delivery. ZIP codes, or Zone Improvement Plan codes, help organize and sort mail by geographic regions. In Delaware, ZIP codes typically begin with the digits 199, and they are further differentiated to represent specific areas within the state. For instance, Wilmington, the largest city in Delaware, has ZIP codes such as 19801 and 19810. The first digit in the ZIP code generally corresponds to a particular region, while subsequent digits provide more detailed location information. This system enables the United States Postal Service (USPS) to streamline the sorting and delivery process, ensuring accurate and timely mail distribution throughout Delaware.
