Proof of delivery

Proof of delivery (POD) is a method to establish the fact that the recipient received the contents sent by the sender. When the sender sends multiple documents through the mail there is a possibility of some not reaching the intended recipient. Generally post offices provide additional service of guaranteed delivery, known as an Avis de réception (advice or acknowledgment of receipt), wherein they require the recipient to sign a paper and that paper is filed by the postal service for a specified number of days.
