How to cancel 3T AS by mail
Gather your account details
3T AS will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Write your request
3T AS is based in Norway, so the letter goes out in Norwegian, built from our Norwegian template. Subject line: “Emne: Forespørsel om oppsigelse – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Mail the letter with a receipt
Address the envelope to 3T AS, Oslo, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep proof the letter arrived
The receipt dates your request. Look at your next statement for any 3T AS charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your 3T AS cancellation letter goes
3T AS lists Postboks 4444 Nydalen, 0403 Oslo, Norway as its mailing address.
Postal code 0403 places the address in Oslo, Norway.
The letter greets the reader with “Til den det måtte angå,”; your own details sit under the labels Kontoinnehaver, Fakturaadresse registrert and Registrert e-postadresse.
Prefer to write it yourself? Use our letter template
Before you cancel 3T AS, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- 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.
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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
