Betalingsservice is a direct debit payment service for initiation of collections of payments.
Right to access will give you:
CPR number, name, address, account information, information on what creditors you have given Betalingsservice mandate to, your customer number with the creditor and the Betalingsservice mandate number.
You could also find that information in your online bank or the Betalingsservice App.
If you have a constructed cpr.no. for a joint bank account, you can only get data about that account and Betalingsservice mandate from your bank. Only the bank knows the connection between the constructed number. and the real cpr.no.
If you have a request regarding your bank account, e.g. change of account number or address, you should contact your bank. If you have a request regarding your mandate, you should contact the creditor.
