We'll cover situations where you might have misplaced it, or if you're assisting another business with their compliance needs.

It is used to identify a business for tax purposes. Think of it as the Social Security number for your company. The IRS uses EINs to administer tax laws. The number is formatted as XX-XXXXXXX.
