An employer identification number (EIN) is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to businesses operating in the United States. It is used to identify the business for tax purposes and is required on various tax forms, including Forms W-2 and 1099. If you need to find your EIN but do not have a W-2, there are a few different ways to do so.
One option is to contact the IRS directly. You can call the IRS at 1-800-829-4933 or visit their website at irs.gov. You will need to provide the IRS with your business name, address, and Social Security number.
