The carrier tries to make two deliveries. After two delivery attempts have been made, the shipment will be placed in the DHL carrier warehouse on hold for up to 10 days at the most. You can contact the DHL Customer Care at the number shown on the notice that the carrier left in your absence during that time period and provide instructions for a new delivery or, as an alternative, notify that you yourself will pick up the package at the DHL reception desk closest to you.
