How can you find your ein?

Contact the IRS. If you applied for an EIN and the IRS approved your application, you should have received a notice indicating your EIN. If you do not have this document, you can retrieve your EIN by calling the IRS Business and Specialty Tax Line at 800-829-4933. The line is open weekdays from 7 a.m. to 10 p.m. in your local time zone.
