Doing a background check without a Social Security number from a rental can often be done. I was told I needed to fill out a rental application (where ssn is required) before viewing it because he gets several requests a day.A social security number is not mandatory for a credit check. You can order a credit report with a name and address. Since the SSN is a required field, have them temporarily enter any 9-digit number so they can continue filling out their rental application and complete it. A typical background check only requires an individual's name and other information, while a credit check involves an SSN check. Q: Am I required to give my social security number for credit checks for property rentals? You can talk to them about your concerns, but they want to check your credit the rasiest way for them to do that is to use your SSN. The fair housing act doesn't allow landlords to ask your age however, they can get your social security number in order to run a credit check.
