What is an Employer Identification Number (EIN)?

An Employer Identification Number (EIN) is a nine-digit number that looks like a Social Security number. This number is used by the United States Internal Revenue Service (IRS) to identify your business for tax purposes. Another name for an Employer Identification Number is a Federal Tax Identification Number (FTIN).

Further, an EIN is required for companies in order to file taxes as a separate entity. It is required to file taxes as a separate entity as opposed to filing taxes under an individual’s Social Security number (SSN). With an EIN, a business owner does not have to use their Social Security number in order to file taxes for their business. Instead, they use the EIN.
