There are cases where DHL does not leave a notification card when the recipient is not available at home. Here are some possible reasons:
- Limited Number of Cards: Sometimes, the couriers are equipped with a limited number of notification cards, which may be exhausted by the time of delivery.
- No Access to the Mailbox: In other instances, the courier may not have direct access to the mailbox to leave the card.
Typically, the notification card is sent by mail in the following days.
