The addressee has 15 calendar days to pick up your registered mail with confirmation of receipt (in the Post Office or Post Point mentioned on the failed delivery notice). If the addressee does not pick up your mail within 15 calendar days, it will be sent back to you.
Certified Mail provides proof of mailing and a delivery record, primarily used for important documents where confirmation of receipt is necessary. It is less expensive and faster than Registered Mail but offers less security.
What's the difference between Registered Mail and Certified Mail? While Certified Mail provides proof of shipment and delivery, Registered Mail provides updates throughout the entire shipment process.
Note: Sending a registered letter provides a higher level of security, proof of mailing, and delivery confirmation compared to regular mail. This method is often preferred for important or sensitive documents, legal notices, or valuable items also.
