Registered Service: Secure Delivery You Can Trust

When your business mail requires assurance, tracking, and accountability, SingPost’s Registered Service provides complete peace of mind. Designed for confidential, legal, and high-value correspondence, this service offers proof of posting, tracking, and recipient signature confirmation. Whether you're sending invoices, contracts, legal notices, or official letters, Registered Service ensures secure handling from start to finish, both locally and internationally.

SingPost enables the mailing of items up to 500g via Registered Service within Singapore. For overseas postings, we accept items weighing up to 2kg, but this service is only available if it is valid for the destination country. Registered Service operates as an affordable and reliable sign-for doorstep delivery, requiring a signature upon receipt in Singapore and most other destinations.

Please note that Registered Service is exclusively for the delivery of paper-based items, such as letters, documents, and printed materials of no commercial value.

Registered Service Tracking Number Information

Within Singapore (local sender to local receiver, “local to local”) and International posting (local sender to international destination, “local to international”)

For every Registered Service item, a 9-digit tracking number starting with RA and ending with SG (e.g., RA123456789SG) will be provided. Senders and recipients can use this tracking number to check delivery status, confirm delivery or pickup. This tracking only reflects major milestones rather than detailed scan-by-scan updates.

  • For “local to local” Registered Service, this can be done either at the post office, POPStop service points or via POPDrop kiosks. 
  • For “local to international” Registered Service, this can only be done at the post office.
  • Businesses which have a corporate account with SingPost can speak with their Account Managers for details of the Registered Service.

International Sender to Local Recipient

Kindly check with the sender for the specific Registered Service number, which may be in a different format from SingPost’s. 
 

Value-Added Services

Advice of Receipt (AR)

AR is an optional service that is available for opt-in when registering a mail item. With AR service, the recipient will be requested to sign on the AR card and this card will be automatically returned to the sender via mail upon successful delivery. This optional service is available at $1.00, on top of the registered fee plus postage.

The Signed Delivery Receipt is only available to the sender as a digital copy upon a successful request from the recipient’s Postal Administration.

This request may require up to 3 working days (for local) and at least 25 working days (for overseas) to be processed.

Digital Copy of Signed Delivery Receipt (after posting)

If you require a digital copy of the signed delivery receipt and you have not opted for the AR service at the point of posting, a nominal fee may be charged.

To request for a digital copy of the signed delivery receipt, please fill in the Enquiry Form.

For other feedback or requests, please call 1605.
