    Here is a link for business codes:

    Scroll down to pages 17 and 18.

    This is the answer to the question "what do I enter in Schedule C line B Principal Business Code?"

     

    But this question was still unanswered. "Trade or Business ID Number" is requested in Schedule C worksheet line C.  The principal business codes don't fit in this line. The format should be an employer ID number.  Unfortunately, it is a required field and many of us don't have an employer ID number.  Any advice?

     

    Thanks.

    If you are a sole proprietor/independent contractor, you can use a social security number.
