Is it legal for a car dealership to run your credit without approval I did not provide them my SS number have no idea how they got it?

It is generally not legal for a car dealership to run your credit without your explicit written permission. Some exceptions to this rule may exist, such as if you have already provided them with your Social Security number or if you have authorized them to do so in some other way, such as by signing a credit application form.

It's important to protect your privacy and credit information. If you believe a car dealership has run your credit without your permission, you should contact them immediately and demand an explanation. You may also want to consider filing a complaint with the Consumer Financial Protection Bureau (CFPB) or your state's attorney general's office.

Below are some tips to help you protect your credit information:

- Never share your Social Security number unless you are certain it is necessary and are dealing with a reputable company.

- Review your credit reports regularly and dispute any inaccurate or fraudulent information.

- Consider placing a credit freeze on your credit reports if you are concerned about identity theft.
