The preferred method of applying for an employer ID number is through the IRS website. The application is only for businesses based in the United States or its territories, explains the IRS. Application information is verified during an online session, and the number is issued immediately. The principal business owner must have a valid Social Security number or personal tax identification number to use the online application.
It is also possible to apply for a federal employer ID number by filling out a Form SS-4 application and faxing or mailing it to the IRS at the number or address indicated on the form. The ID number can be faxed back within four days. A mail application takes four weeks to process, notes the IRS.
