Do educational loans have to include student’s ss#?

[Anonymous]

My child’s father missed the deadline for setting up a payment plan for his portion of DC’s college tuition this semester. If he takes out an educational loan, do they all require including the students Social Security number? Or can some private loans (not FAFSA-related) be applied for just using the parents Social Security number? I am concerned that my ex will take out a loan and not make the payments in a timely manner, and that this would have an impact on DC‘s credit rating. TIA
