Applying for EIN?

I have the forms, but am confused! Has anyone applied for an EIN for their condo association? We are a Trust with 5 Trustees. The EIN application form asks for the Trust to list a SSN of the "grantor." There is no grantor. Do we have to list one of the Trustees' SSN? Any help would be appreciated, even if to tell me to hire a CPA to do this for us!

Employer ID Numbers (EIN) - How to Apply

APPLY BY EIN Toll-Free Telephone Service
Taxpayers can obtain an EIN immediately by calling the Business & Specialty Tax Line
(800-829-4933). The hours of operation are 7:00 a.m. - 10:00 p.m. local time, Monday through Friday. An assistor takes the information, assigns the EIN, and provides the number to an authorized individual over the telephone.

APPLY BY FAX
Taxpayers can FAX the completed Form SS-4 application to their state FAX number (see Where to File - Business Forms and Filing Addresses), after ensuring that the Form SS-4 contains all of the required information. If it is determined that the entity needs a new EIN, one will be assigned using the appropriate procedures for the entity type. If the taxpayer's fax number is provided, a fax will be sent back with the EIN within four (4) business days.

APPLY BY MAIL
The processing timeframe for an EIN application received by mail is four weeks. Ensure that the Form SS-4 contains all of the required information. If it is determined that the entity needs a new EIN, one will be assigned using the appropriate procedures for the entity type and mailed to the taxpayer.
