South Dakota Federal Tax ID numbers are issued by the IRS in a nine-digit format such as 12-3456789.
They uniquely identify your business to the government in the same way that Social Security Numbers do for individuals. But various non-government vendors will also request the number during routine commerce in South Dakota. For example, South Dakota banks will require you to provide one before opening a business bank account.
