Important Information about the Online EIN Application

The online EIN application is available for all entities whose principal business, office or agency, or legal residence (in the case of an individual), is located in the United States or U.S. Territories. The principal officer, general partner, grantor, owner, trustor, etc., must have a valid Taxpayer Identification Number (Social Security Number, Employer Identification Number, or Individual Taxpayer Identification Number) in order to use the online application.

If you are a third party, you must retain on file a completed copy of the Form SS-4 signed by the customer, and the signed statement authorizing you to file the online application.
