People have to provide some details to get car insurance quotes, including their name, age, address, gender, driving record, and marital status. Consumers also tell the insurer about their vehicles. This is necessary so the insurer can assess the risk of providing coverage and give an accurate price quote. Most insurers ask for a person's Social Security number and vehicle identification number (VIN), but they don't have to provide this information to get a quote. Offering it can streamline the process and ensure that auto insurance quotes are as accurate as possible.
