A Federal Employer Identification Number, often referred to as an EIN or FEIN, is a unique number issued by the Internal Revenue Service (IRS) to identify a business. 

Do you need a federal employer identification number (EIN or FEIN)? 

Most businesses are required to obtain a federal employer tax identification number. 

If your business is operating as a Sole Proprietor, you can register your business using your Social Security Number (SSN); however, if you would like to register your business name or Doing Business As (DBA) on your business-related accounts a FEIN may be required.
