Postal codes and localities in Delaware

Browse localities and postal codes in Delaware, United States.

This Delaware page brings together 96 ZIP Code records from the published United States directory. Use the table to compare codes with their listed cities and localities, then open an individual ZIP Code when a detail page is available. A locality name is a useful search clue, but it does not confirm delivery to every street address in that area. Check the complete destination with USPS before using a result on important mail.

The United States Postal Service uses five-digit ZIP Codes and, for more specific delivery information, ZIP+4 codes. A ZIP Code can be associated with more than one place, so the state and city shown in a directory are a starting point rather than proof that a complete mailing address is deliverable. Check the full destination address before posting mail.
