You can’t find it online. You can contact the customer support and ask them to send it to you, or you walk into an o2-shop with your identity card.

Hi @maniamadrid,

welcome to our community. Are we talking about DSL or mobile contract? I just ask because of finding a cancellation request on your mobile contract.So obviously it worked. But there is no DSL according to your contract details. So did you take over a DSL contract on your behalf? If not, you can’t cancel a contract which is not yours.

Waiting for further details.

Greetings

I only make the mobil contract, but I don’t have the contract. So, I was asking if there is another way to find it. 

Okay, fine @maniamadrid

I resend the four digit code by post. You will receive it within the next days.

Greetings

I don’t live anymore in Germany. Can you send to a friend of mine in Germany???

Unfortunately not @maniamadrid

Because of data security it is forbidden. It is like telling someone the PIN of your debit card. Can I assist you in any other way?

Greetings

No
