To send a letter or package it is important that you have paid sufficient postage. It is the sender who is responsible for the shipment's correct postage.
If a consignment is missing or has too little postage, the sender must pay the missing postage and an additional fee. If we do not know the sender, it is the recipient who has to pay. 61.– kroner for invoice and 12.– kroner per letter.
To find the right postage, see prices for packages and letters.
