Registered Article

Want peace of mind to know if the recipient received the mail? Register your mail.

All mail items up to 2 kg may be accepted for registration provided the service is available to the country of destination. Registered Article is a Sign-For service that requires a signature on delivery in Singapore and most destinations. Registered Article provides an added security for mail up to 2 kg.

This service is ideal for confidential or important items which require special handling, processing and accountability. Any postal item can be registered for delivery locally or internationally.

Registered Article does not provide detailed online tracking capability. It is not mandatory for registered items to be scanned at every stage of the delivery process be it for local or overseas delivery.

Please note that for registered articles to overseas, the scan events may differ from post to post. A scan event will be shown if and when they are provided by the overseas postal administrations. For countries with no online tracking updates, SingPost will check with the overseas postal administrations on the status if the addressee did not receive the item after a stipulated time. Under the international postal agreement, overseas postal administrations may take up to 60 days to reply.
