1099-Misc Missing complete Payer's Federal ID No.

I received a 1099-Misc from Oil & Gas revenue from a company, but they only provide a portion of their Payer's Federal Identification Number!  TT wants the complete number.  I tried contacting the company, but no response.  They may have gone out of business.  What can I do?

 

Thanks in advance for any and all sage responses!
