The IRS has an online application (as well as phone and paper applications) to obtain an EIN. The process is free and takes only a few minutes. At the end of the simple application, you receive a generated form letter which includes your nine digit EIN. (Note: you will need to enter your social security number on the application.)
According to the IRS, a sole proprietor must obtain a new EIN if he is subject to a bankruptcy proceeding, is incorporate, operates as a partnership, or purchases or inherits an existing business that is operated as a sole proprietorship.
