Rental Applicants - Capture SS# when using SmartMove?

[Mike M.]

I'm going to use SmartMove for my credit and criminal background checks.  I'm finishing up my paper application now and wanted to know if it made sense to record the applicant's SS number on the application?  Obviously one benefit of SmartMove is that personal information is kept personal.  I think I want it on the application to assist with obtaining judgments and other legal proceedings IF SS# is used for such.

Questions:  1) Is a SS# necessary for judgment recording (say, for damages or unpaid rent); 2) What do other SmartMove users record on their paper apps?

Thanks much.
