Add a new location to your existing business

Step 1: Consult the Business Licensing Guide

The Business Licensing Guide is an online service that gives you licensing information and forms based on your business activity and location. When you tell us about your business (for example, restaurant in Seattle), the Business Licensing Guide creates a customized guide sheet that includes the forms you’ll need and a list of agencies to contact. If you need additional information, or prefer the guide sheet be mailed to you, please call Master License Service at (360) 664-1400.

Step 2: File a new Master Business Application and supplemental forms

There are three ways to submit a Master Business Application:

File online

1. Complete the online Master Business Application.
2. Pay with a MasterCard or Visa credit card.

Filing online isn’t recommended for some businesses. See the list of businesses that should not file a Master Business Application online for details.

File by mail

1. Complete the Master Business Application AND any supplemental forms that apply to your business. To find out which supplemental forms you’ll need, see the Business Licensing Guide.
2. Send your completed application, supplemental forms, and a check or money order payable to “Washington State Treasurer” for the fees to:
   
   Master License Service
   Department of Licensing
   PO Box 9034
   Olympia, WA 98507-9034

If your business needs specialty licenses, including liquor or lottery licenses, you should file your Master Business Application by mail.

File in person

Visit any business licensing office.

Step 3: Research additional licensing requirements

For licenses not available through Master License Service, contact the agencies, cities, or counties listed on your Business Licensing Guide Sheet.
