Why Your Garaging Address Determines Your Premium
You moved three weeks ago. Your Tennessee car insurance policy still lists your old address. You're not sure whether you need to report the change, and you're worried that updating it will trigger a premium increase across all three vehicles on your policy.
Your garaging address—the location where each vehicle is parked overnight—is a rating factor carriers use to calculate your premium. When you move, the carrier re-rates your entire policy based on the new address's theft rate, accident frequency, and claims history. That re-rating applies to every vehicle on the policy, not just one car. Tennessee law requires you to report address changes to your carrier, and failing to do so can void coverage when you file a claim.

339.9 per 100k
Tennessee's motor vehicle theft rate is 339.9 per 100,000 population. When you move from a lower-theft county to a higher-theft area, carriers adjust your comprehensive premium upward to reflect the increased risk at the new garaging location.

When Tennessee Carriers Re-Rate Your Multi-Car Policy
Tennessee carriers re-rate your policy the moment you report a garaging address change. The new address triggers a recalculation of every vehicle's premium based on the new location's risk profile. If you moved from a rural county to Nashville or Memphis, expect your premium to increase. If you moved from a high-density area to a lower-risk county, your premium may drop.
The re-rating applies to every vehicle on the policy, even if only one car's garaging address changed. Most multi-car policies require all vehicles to share the same garaging address to qualify for the multi-car discount. If you moved but one vehicle is still garaged at the old address—for example, a car your college-age child drives at school—you must report both garaging addresses separately, and the carrier may split the policy or adjust the discount.
Tennessee law requires you to notify your carrier of an address change within a reasonable time, typically interpreted as 30 days. Carriers include this requirement in policy terms. If you file a claim and the carrier discovers your actual garaging address differs from the address on file, the carrier can deny the claim for material misrepresentation.
Delaying an address update to avoid a premium increase can void your coverage at claim time. Tennessee carriers deny claims when the garaging address on file is incorrect.
How to Report Your Address Change
Log in to your carrier's online portal or mobile app and navigate to the policy details section. Look for an option labeled "Update Address," "Change Garaging Location," or "Policy Information." Enter the new address for each vehicle. The system will calculate the new premium and display the adjusted rate before you confirm. If your premium increases, the carrier will bill the difference pro-rated to your next renewal. If it decreases, you'll see a credit on your next statement.
If you prefer to update by phone, call your carrier's customer service line or your agent directly. Provide the new garaging address for each vehicle and confirm the effective date of the change. Ask the representative to confirm the new premium for each vehicle and the total policy premium after the adjustment. Request written confirmation of the address change and the new rate, either by email or through the carrier's online portal.

What Happens When One Vehicle Moves to a Different Address
If one vehicle on your multi-car policy is garaged at a different address—for example, your teenager's car is at college in Knoxville while your other two vehicles are garaged at your home in Chattanooga—you must report both garaging addresses to the carrier. Most carriers allow different garaging addresses on the same policy, but the multi-car discount may be reduced or eliminated if the addresses are in different rating territories.
Some carriers require you to split the policy when vehicles are garaged in different cities or counties. The carrier will create two separate policies, one for each garaging location, and you'll lose the multi-car discount that applied when all vehicles were on one policy. Other carriers keep all vehicles on one policy but rate each vehicle individually based on its garaging address. Ask your carrier how it handles multiple garaging addresses before you report the change.
If the vehicle at the second address is driven primarily by a household member who lives at that address full-time—such as a college student—the carrier may require you to list that address as the primary garaging location for that vehicle and adjust the driver assignment. This can increase the premium for that vehicle if the new address is in a higher-risk area or if the driver is younger than 25.

$936.15/year
Tennessee drivers paid an average of $936.15 per insured vehicle in 2023. Your actual premium depends on your garaging address, driving record, vehicle type, and coverage selections. Moving to a higher-risk area increases your premium; moving to a lower-risk area decreases it.

How Moving Affects Your Multi-Car Discount
The multi-car discount applies when all vehicles on the policy share the same garaging address and are rated in the same territory. When you move, the carrier recalculates the discount based on the new address. If the new address is in a different rating territory—defined by ZIP code, county, or city—the discount percentage may change. Some carriers offer larger multi-car discounts in lower-risk areas; others keep the discount percentage constant regardless of location.
If you moved out of state, Tennessee carriers cannot continue coverage on vehicles garaged outside Tennessee. You must obtain a new policy in your new state. If you're moving temporarily—for example, a six-month work assignment—and plan to return to Tennessee, ask your carrier whether it can keep your Tennessee policy active with an out-of-state garaging address for the duration of the assignment. Most carriers allow this for short-term moves but require you to transfer to an in-state policy if the move becomes permanent.
Report Your Address Change Within 30 Days
Tennessee carriers require you to report address changes within 30 days of the move. This deadline appears in your policy terms under the "Duties After a Loss" or "Policy Changes" section. Missing the deadline does not automatically void your policy, but it gives the carrier grounds to deny a claim if the incorrect address affected the risk calculation.
If your premium increases after the address update and you cannot afford the new rate, contact your carrier before the next billing cycle. Ask whether you can adjust your coverage—raise your deductibles, drop collision or comprehensive on older vehicles, or reduce coverage limits—to lower the premium. Do not let the policy lapse.
