How to cancel Six by mail
Start with your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Six is only as good as the details it quotes.
Prepare the letter
The letter asks Six to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Cancellation Request – [your name]”. Postbye fills it in from our English template.
Send it by certified mail
Take the letter to the post office and ask for certified delivery to V6P 5A0 Vancouver. Keep the tracking number it gives you.
Keep the delivery receipt
It shows the date Six received your letter. Check your next statement: no Six charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Six cancellation letter goes
Six lists P.O. Box 30042, V6P 5A0 Vancouver, Canada as its mailing address.
“P.O. Box 30042” is a post-office box or mail-sorting line, so it takes post and not couriers: certified mail is the right way to reach it.
Inside, the salutation reads “To Whom It May Concern,”, followed by your details under Account holder, Billing address on file and Email on file.

Before you cancel Six, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
