Gym memberships, cell phone plans, utility bills, unpaid parking tickets, etc. will all report to your credit report if you miss payments. Debt, not just credit cards. A delinquent account on your account will drop it by 100-150 points immediately.
The information you provide with payment - name and address - is sufficient to add a delinquent account to your credit report, which will immediately tank it. Again, SSN is not necessary for this.
