Good news! DHL consignments are not required to be deleted in DHL eCommerce; the consignment will not become active, and you will not be charged until it is scanned by a driver and enters the DHL Network.
Therefore, if you need to make changes, you can:
select your order
make and save any changes
Click "Print Labels"
You will be prompted to Update or RePrint. Choose "Update"
Check your label includes the updated details
Discard any old unused labels
To ensure the right tracking number is used, discard old labels. Every time a label is changed or updated, it must be reprinted, and the parcel relabelled with the newest label, as the old one then becomes unusable, and the parcels may be returned.
