Federal Employee Identification Number (FEIN or EIN)
Also known as the Federal Employer Identification Number (FEIN) or the Federal Tax Identification Number (TIN/EIN), the EIN is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to business entities operating in the United States for the purposes of identification. When the number is used for identification rather than employment tax reporting, it is usually referred to as a Taxpayer Identification Number (TIN), and when used for the purposes of reporting employment taxes, it is usually referred to as an EIN.
An Employer Identification Number or EIN (also known as Federal Employer Identification Number or FEIN) is the corporate equivalent to a Social Security number, although it is issued to anyone, including individuals, who have to pay withholding taxes on employees. It is also issued to entities, such as states, government agencies, corporations, limited liability companies, and any other organization that must have a number for a purpose in addition to reporting withholding tax, such as for opening a bank or brokerage account.
