How many days are postal items stored at the post office if I do not collect them at once?

After receipt of the notice K 11, it is recommended to arrive at the post office to collect the item as soon as possible - postal items weighting above 500g are stored free of charge for a period of 15 calendar days from delivery of the notice K 11. After the expiry of this term, a charge of EUR 0.87 per day is applied. When collecting the item you will have to pay the charge for storing your item (postal items are stored for a period given in the notice K 11). In the event the addressee does not collect the item within the indicated period, the item is returned to the sender. Upon written request of the sender or addressee, items may be stored up to 2 months (except for items containing procedural documents).
