How to cancel 4based 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 4based holds, so the request can be matched to your account.
Write your request
Postbye writes the letter in German from our German template, because 4based's address is in Germany. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks 4based to end the subscription, stop all further charges and confirm in writing.
Mail the letter with a receipt
Send the letter to the Stuttgart mailing address shown below by certified mail. Keep the tracking number safe.
Hold on to the receipt
It shows the date 4based received your letter. Check your next statement: no 4based charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your 4based cancellation letter goes
4based takes its post at Lindenspürstraße 32, 70176 Stuttgart, Germany, which is where a cancellation letter belongs.

Before you cancel 4based, check these
- Check your next statement: no charge should appear after the cancellation date.
- 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.
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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
