To buy car insurance, you need personal identification details for every driver on the policy, your vehicle’s year, make, model, and VIN, your driving history, and a payment method for the down payment. Most people can gather everything in under an hour, and you don’t need all of it just to get quotes. Here’s what to have ready at each stage.
Personal Information for Every Driver
Insurance companies need basic details about each person who will be covered on the policy. For every driver, have the following ready:
- Full legal name and date of birth. Your age is one of the biggest factors in pricing.
- Driver’s license number. The insurer uses this to pull your motor vehicle report, which shows accidents, tickets, and license suspensions.
- Social Security number. Not always required for a quote, but most companies ask for it before binding a policy. They use it to check your credit-based insurance score, which influences your rate in most states.
- Home address. Where you park your car overnight affects your premium because claim rates vary by ZIP code.
If you have a teen driver or a spouse who will use the car, you’ll need their license numbers and dates of birth too. Student drivers with good grades may qualify for a discount, so have a recent report card or transcript handy if that applies.
Vehicle Details
You can get a ballpark quote with just the year, make, and model of your car. But when you’re ready to actually purchase the policy, you’ll need the vehicle identification number (VIN), a 17-character code found on your registration, title, or a small plate on the driver’s side of the dashboard where it meets the windshield.
The VIN tells the insurer the exact trim level, engine size, and factory-installed safety features. Vehicles with higher safety ratings and lower repair costs are cheaper to insure, so the specific trim matters more than you might expect. Two versions of the same model can have noticeably different premiums.
You’ll also be asked for your estimated annual mileage. If you skip this question while getting quotes, insurers typically assume you drive 12,000 to 15,000 miles per year. If your actual mileage is significantly higher or lower, your final rate will change once you provide the real number. Some companies ask you to verify mileage with an odometer photo before the policy is finalized.
Your Driving and Insurance History
Insurers pull your driving record automatically using your license number, but it helps to know what’s on it before you start shopping. Most companies look back three to five years for accidents and moving violations, though serious offenses like a DUI can stay on your record and affect your rates for up to ten years depending on the state.
You’ll also be asked whether you currently have insurance, and if so, who your carrier is and when your policy started. A gap in coverage, even a short one, typically raises your premium because insurers view uninsured periods as a risk signal. If you’re switching from another company, having your current policy number and renewal date makes the transition smoother and helps avoid any lapse between policies.
If you’ve never had insurance before, expect slightly higher rates. Some companies offer a discount if you’ve completed a defensive driving or safe driving course, so mention it if you have.
Deciding How Much Coverage You Need
Before you finalize a policy, you need to choose your coverage levels. Every state except one requires you to carry liability insurance, which pays for injuries and property damage you cause to others in an accident. Each state sets minimum dollar amounts, commonly structured as three numbers: a per-person bodily injury limit, a per-accident bodily injury limit, and a property damage limit. Your state’s minimums are the legal floor, but many drivers carry higher limits because the minimums often aren’t enough to cover a serious crash.
Beyond liability, you’ll be asked about several optional coverages:
- Collision pays to repair your own car after an accident, regardless of who caused it.
- Comprehensive covers theft, vandalism, hail, flooding, and other non-collision damage.
- Uninsured/underinsured motorist protects you if you’re hit by a driver who has no insurance or not enough of it. Some states require this coverage.
- Medical payments or personal injury protection covers medical bills for you and your passengers after an accident, regardless of fault.
If you’re financing or leasing the vehicle, your lender will almost certainly require both collision and comprehensive coverage. If you own the car outright, those are your choice, but dropping them means you’d pay out of pocket if the car is totaled or stolen.
Payment and Down Payment
You’ll need a payment method to activate your policy. Most insurers require a down payment before coverage begins, typically equal to one to two months of premiums. This acts as a deposit and is not refundable if you cancel.
Several factors influence how large that down payment is. Your credit history plays a role: a stronger credit score generally means a lower deposit. Drivers classified as higher risk, whether due to a poor driving record, a coverage lapse, or age, may be asked to pay more upfront. Some companies offer the option to pay the full six-month or twelve-month premium in one lump sum, which often comes with a discount since it eliminates monthly billing fees.
You can usually pay with a debit card, credit card, or bank account transfer. Have your payment details ready when you’re prepared to bind the policy, because coverage doesn’t start until the payment processes.
What You Need for Quotes vs. Buying
You don’t need every document from the start. Shopping for quotes and actually purchasing a policy require different levels of detail.
To get comparison quotes online, you generally need your ZIP code, date of birth, the year, make, and model of your car, and a rough idea of your driving history. This is enough to see ballpark pricing from multiple companies in a few minutes.
When you’re ready to buy, the insurer will ask for your driver’s license number, VIN, Social Security number, prior insurance details, and your payment information. At that point, the company verifies your driving record and credit, and the final premium may adjust up or down from the initial quote based on what they find. Having everything accurate from the start means fewer surprises at checkout.
