When filing a tax return that includes a SCH C business for which you have been issued an EIN, you will have both your SSN and EIN  on the tax return. The SSN will be at the top of page 1 of the 1040. Then EIN will be on the top right of the SCH C in box D and the SSN will also be on the SCH C in the box above box B.
