Regulations Governing the Handling of Mail Article 28

“Registered mail” refers to a mail that bears an expression that means “Registered Mail” on the cover which is submitted to a post office branch or a person appointed by Chunghwa Post for delivery, for which the sender receives number registration certificate and proof of mailing and pays the fee for a registered mail. Mails including parcels, express mails and collect-on-delivery mails also belong to registered mails.At the time of posting an item of registered mail, the sender may pay a fee (designated in rate charts) to receive an acknowledgement-of-receipt. This acknowledgement-of-receipt is filled out by the sender with the form supplied by the post office at the time of mailing and later returned to the sender after having been signed by the recipient.If the delivery post office confirms clearly in writing that it has delivered the item, then that shall be deemed as the equivalent of having been signed by the recipient.
