Guarantor on a Lease

[Misty Quaintance]

If I have a guarantor sign an addendum to a lease do I need them to provide their social security number or drivers license number? The form I have from Bigger Pockets pro membership asks for social security, but the first person did not fill this in. I'm wondering if this will be an issue or if I can ask for something like a drivers license instead. Arkansas is the state where the rental is located.
