Insufficient franking

For every letter sent with insufficient or no franking, the sender is billed the missing franking as well as a processing fee of CHF 1.00 per consignment. The surcharge corresponds to the expenses incurred for handling an insufficiently franked consignment. If the sender is unknown, the outstanding sum is requested from the recipient (without the CHF 1.00 surcharge).
