Why is my PostNL tracking not updating or stuck?

Tracking can pause for a few reasons: the label was created but the parcel has not been handed to PostNL yet, the item is in transit between sorting centres, or an international parcel is moving between carriers or sitting in customs. International shipments often go quiet for a day or two during the cross-border leg and then resume once they reach the destination country. If your parcel is overdue and tracking has not updated for several days, contact the sender or PostNL customer service.
