I have seen so many threads about this topic and have already applied everything but couldn't find the Contract number. I bought a device last week and need to register on O2 portal. I need this contract number for login on mein O2 portal.

Hello
thank you very much for your question in our o2 Community! 
If you have bought a new device, you will find your contract number in the corresponding invoice that is/was sent to you. Have you already received this and been able to view your contract number there in the meantime?
Have a nice evening
