AimDiz 0 Posted August 18, 2016 Hey all, Does anyone have recent experience getting a business license in Washington State using an ITIN or EIN, instead of a SSN? I keep reading it's possible to start a business without a SSN, but having a hard time finding info specific to Washington. The application for the business license appears to require a SSN, so wondering if there's another way? Can I just input an ITIN or EIN? Thanks in advance.
