I have a customer sole owner of an 1120S.  He has sold the property that is in the 1120S name.  The title company is wanting proof of his ownership from the IRS.  I know the original EIN was gotten in 1986 and he can request a copy of the letter CP575.  By mail takes to long and by phone the so called business and specialty line you never get anyone. 

Do y'all have any suggestions?
