Delaware Address Format (2026) — How to Write a Delaware Address

How to write a Delaware address: street, city, state code, and ZIP, with a Delaware example, city links, and a pre-filtered generator.

A Delaware address follows the standard US order: street, apartment or suite, city, two-letter state code, and ZIP code. The state code is DE.

This page adds the state-specific details that are easy to miss: the capital, the largest city, the timezone, a ZIP example, and the state sales-tax position.

How to write a Delaware address

Write the street address first, then the apartment or suite if there is one, then the city, the state code DE, and the ZIP code. Put the country on the last line for international mail.

Example format: 123 Example Street, Apt 4B, Wilmington, DE 19801, United States.

Sales tax and address checks

Delaware has no state-level general sales tax, but local taxes or product-specific rules may still apply.

An address does not decide the final tax rate on its own. The seller, the product category, local rules, and nexus can all change the result.
