Try OP's online financing service
If you’ve bought a car using hire purchase, you can view your financing information on OP's online financing service (in Finnish). There you can also apply for a change in your bill's due date. You can also order an authorisation to take the vehicle abroad or apply for a repayment holiday through the service. You can log into the service with your personal online banking user identifiers issued by any Finnish bank or with a Mobile ID.
