Problems with Payout method

[Kira23]

Hello, i updated my payout method many times, but everytime there is a problem. A few days ago i got a mail from airbnb saying they have send my money but the day after there is a problem again and the money has been send back. I have been in contact with the help center, but nothing helps. 

Can anyone please tell me what cpr is? I have set my payout method to be bank transfer and i can choose between cvr (if i have a company, right?) and cpr. What is the cpr?

Hope someone can help me out here since google was not a help at all.
