If you are not going to be in to receive your parcel there are a number of options available. However, unfortunately DPD does not offer customers the option to change their 1 hour delivery slot. Alternatively, you can request your parcel to be left in a safe place or delivered to a trusted neighbour. Use your DPD reference number and postcode to change the details of your delivery. If none of these options seem convenient to you, DPD offers customers the chance to change your delivery date. Find out more about how to change your delivery online at DPD.
