partnership representative and designated individual on the Form 1065, U.S. Return of 

Partnership Income, and Form 1066, U.S. Real Estate Mortgage Investment Conduit 

(REMIC) Income Tax Return, filed with the IRS?

Representative, taxpayers may enter all 0s (example: 00-0000000 or 000-00-0000) for
