How to cancel Car Insurance Net by mail
Start with your account details
You will need the policy number, the registration number of the vehicle and the date you want cover to end. Use exactly the details Car Insurance Net holds, so the request can be matched to your account.
Set out the request
State plainly that you want the Car Insurance Net account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Subscription termination – Car Insurance Net”).
Post it with proof of delivery
Use certified mail for the 98104 Seattle address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
Keep the tracking record with your copy of the letter. If Car Insurance Net bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Car Insurance Net, check these
- If you pay monthly, ask for the instalment authorisation to be ended as well, so no further payment is collected after the end date.
- Some insurers need proof of the new cover or a statement that the vehicle is sold. Ask what they accept and send it with the request.
- Do not cancel until the new policy is active. Driving uninsured, even briefly, can carry fines and penalty points.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a car insurance policy
Car insurers cancel by policy and by effective date, and a gap in cover is a real risk, so the request has to name the vehicle and the exact date cover should stop, ideally after the new policy has started.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
