What you need before you contact an insurer
To get a car insurance quote, you need your driver's license number, the vehicle identification number (VIN) from your car, and your driving history. Most insurers will also ask for your current coverage (if you have it), the date you want coverage to start, and how you plan to use the car — commuting, occasional driving, or business use. You do not need to have all of this memorized; you can gather it as you shop.
The actual documents you'll need depend on whether you're insuring a car you already own or one you're buying. If you own the car, have the registration or title handy. If you're financing or leasing, the lender or leasing company will have specific insurance requirements, and you may need to show proof of coverage to them before you drive off the lot.
Key Takeaways
- Your driver's license number, the car's VIN, and your driving history are the three pieces of information every insurer will ask for before quoting you.
- If you're financing or leasing a car, the lender requires proof of coverage before you can take possession, so contact insurers before signing the loan papers.
- You'll need to decide on coverage limits and deductibles before you buy, and these choices directly affect your monthly premium.
- If you have a gap in coverage or are a new driver, some insurers will ask for more documentation or charge higher rates.
Your driver's license and driving history
Your driver's license is the first thing an insurer verifies. Have the number ready when you call or fill out an online quote. The insurer will pull your driving record from your state's Department of Motor Vehicles, so you don't need to provide it yourself — but you should know what's on it. Accidents, traffic violations, and suspensions all affect your rate.
If you've had a major violation or accident in the past three to five years, tell the insurer upfront. Hiding it won't work; they'll find it anyway during underwriting, and it can delay your policy or cause it to be cancelled. If you're a new driver or haven't had insurance in several years, some companies will ask for a defensive driving course certificate, which can lower your rate.
Your vehicle's VIN and registration
The VIN is a 17-character code that identifies your specific car. You'll find it on the dashboard (visible through the windshield on the driver's side), on the driver's side door jamb, or on your registration or title. The insurer uses the VIN to confirm the car's make, model, year, and safety features, all of which affect the cost of coverage.
If you're buying a new car and don't have the VIN yet, the dealer can provide it. If you're financing, the lender will have it. For used cars, the seller or the title transfer paperwork will have it. Don't guess or use a partial number — insurers need the full VIN to quote you accurately.
Coverage limits and deductible choices
Before you buy, you need to decide how much coverage you want and what deductible you can afford. Liability coverage pays for damage or injury you cause to someone else; most states set a minimum, but you can buy more. Collision coverage pays for damage to your own car from an accident; comprehensive coverage pays for theft, weather, or vandalism. Deductible is the amount you pay out of pocket before insurance kicks in — higher deductible means lower monthly premium, but you pay more if you have a claim.
Your state's minimum liability limits are public information; your state's insurance commissioner's office or your state's DMV website will list them. If you're financing a car, the lender will require collision and comprehensive coverage up to the car's value. If you own the car outright, these are optional, but most people carry them anyway.
Proof of current coverage or gap documentation
If you already have car insurance, the insurer will ask for your policy number or the name of your current company. This helps them check for gaps in coverage, which some states penalize with higher rates or surcharges. If you're switching insurers, make sure your new policy starts on the same day your old one ends.
If you've been without insurance for more than a few days or weeks, some insurers will charge you more or require additional documentation. A few states allow you to show proof that you had coverage in the past (an old policy declaration page works), but this varies. The safest approach is to overlap your policies by a day so there's no gap at all.
Information about how you use the car
Insurers ask whether you use the car to commute to work, drive occasionally, or use it for business purposes like rideshare or delivery. Your answer affects your rate because commuting means more miles and higher accident risk. If you use the car for rideshare (Uber, Lyft) or delivery, you need commercial or rideshare coverage, which is different from personal auto insurance and costs more.
Be honest about your annual mileage and how far you commute. If you work from home and drive rarely, you'll pay less than someone who drives 50 miles each way. Some insurers offer low-mileage discounts if you drive under a certain number of miles per year.
Additional documents for financing or leasing
If you're financing a car, the lender will require proof of insurance before they release the funds or let you drive the car. You'll need to show the lender a declaration page (a one-page summary of your policy) that lists the car's VIN, the coverage limits, and the lender as the lienholder. The insurer can email this to you within hours of you buying the policy.
If you're leasing, the leasing company has the same requirement. Some dealerships will help you get a temporary insurance card on the spot so you can drive home, but you still need to buy a full policy within a day or two. Don't wait — driving without proof of insurance is illegal in every state, and you could face fines or licence suspension.
Frequently Asked Questions
Do I need insurance before I buy a car?
You need it before you drive the car off the lot. If you're financing or leasing, the lender requires proof of coverage before releasing the money or signing the lease. If you're paying cash, you can buy insurance the same day you buy the car, but you cannot legally drive it without coverage.
What if I don't have a driver's license yet?
You cannot buy car insurance without a valid driver's license. If you're a new driver, get your license first, then contact insurers. Some companies offer discounts for completing a defensive driving course before you insure your first car.
Can I get a quote without giving my Social Security number?
Most insurers will give you a preliminary quote online or by phone without it, but they'll ask for it before you finalize the policy. They use it to pull your credit report and driving record. If you're uncomfortable providing it online, call the insurer directly and ask about their security practices.
What happens if I don't have a current insurance policy to reference?
You can still buy insurance. The insurer will simply pull your driving record from the DMV. If you've been without coverage for a long time, some companies may charge you more or ask for a defensive driving certificate, but you can still get a policy.
Do I need to insure a car before I take it to a mechanic?
No. If you're buying a used car and want a pre-purchase inspection, you can drive it to a mechanic without insurance as long as you have a temporary permit or dealer plate. Once you own the car, you need insurance before driving it on public roads.
