What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to business entities operating in the United States. It's essentially a Social Security number for your business, used to identify your business for tax purposes. Even if you're a sole proprietor, an EIN can offer benefits as your business grows.
