On this page
A Washington address follows the standard US order: street, apartment or suite, city, two-letter state code, and ZIP code. The state code is WA.
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 Washington address
Write the street address first, then the apartment or suite if there is one, then the city, the state code WA, and the ZIP code. Put the country on the last line for international mail.
Example format: 123 Example Street, Apt 4B, Seattle, WA 98101, United States.

Sales tax and address checks
Washington has a state-level base sales tax of 6.5%. Cities and counties may add local tax, so the checkout rate can be higher.
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.
