When placing an order with DPD, it is vital that you provide a local phone number in the destination country. For example, if you are shipping in Italy, you will need to enter an Italian phone number. Failing this, the carrier will not phone you, even in the event of any incidents.
As a general rule, the delivery driver will not contact you before carrying out the delivery. For this reason, it is important to track your parcel in order to find out as soon as possible if delivery has failed (incomplete address, absent recipient, etc.).
