The Internet EIN application is the preferred method for customers to apply for and obtain an EIN. Once the application is completed, the
information is validated during the online session, and an EIN is issued immediately. The online application process 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) to use the online application.
