Search Tips

There are two main ways to search for corporations registered in Washington; by name or by UBI number. To search by name, use the drop down arrow, choose whether the title: "Contains", "Starts With, or "Ends with" the word(s) you plan to enter. On a "Contains" search you may wish to enter any key word or unusual word to locate your entity. On "Starts With" search you may also try your search by typing in the first two words of the entity name. A "Ends With" search is not generally recommended.

Your search will return a list of all companies that contain the words you entered. Please note that on names that contain initials you may wish to contact our office to search for these @ 360-725-0377.

You may also enter a corporations UBI number. You must enter all 9 digits of the UBI in order to return accurate results. Do not enter spaces when searching by UBI number. Note: If a business has a UBI number, that does not automatically mean they are a registered corporation. If you are unable to find results with your search please use the advanced search function, or contact our office for more assistance.

For more complicated search criteria please use the Advanced Search page. This may allow more sources such as searching by Registered Agent name or entity type.
