How to cancel Uio by mail
Get your account details together
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Uio holds, so the request can be matched to your account.
Write your request
Postbye writes the letter in Norwegian from our Norwegian template, because Uio's address is in Norway. It opens with the subject line “Emne: Forespørsel om oppsigelse – [your name]” and asks Uio to end the subscription, stop all further charges and confirm in writing.
Send it by certified mail
Use certified mail for the 0371 Ullevål address in the next section, so the post office records the delivery. Write down the tracking number.
Hold on to the receipt
The receipt dates your request. Look at your next statement for any Uio charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Uio cancellation letter goes
Uio can be reached by post at Problemveien 11, 0371 Ullevål, Norway.
The postcode 0371 belongs to Oslo, Norway, so this is where the envelope is delivered.
The letter is addressed “Til den det måtte angå,” and its details block uses the labels Kontoinnehaver, Fakturaadresse registrert and Registrert e-postadresse.

Before you cancel Uio, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- 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.
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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
