1. Follow the naming guidelines for a Washington LLC:

  • Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
  • Restricted words (e.g. Bank, Attorney, University) may require additional paperwork and a licensed individual, such as a doctor or lawyer, to be part of your LLC.

2. Is the name available in Washington? Make sure the name you want isn't already taken by doing a Washington state LLC name search on the Washington Corporations and Charities Filing System.

To learn more about searching for a Washington LLC name, read our full guide.
