Singapore Post, commonly known as SingPost, is Singapore's national postal and eCommerce logistics provider. Its history dates back to 1858, and today the company combines traditional postal services with parcel delivery, international shipping and logistics solutions for consumers and businesses. SingPost is headquartered in Singapore and supports postal and logistics activity across the Asia-Pacific region, including operations connected with China, Japan and New Zealand.
For customers sending items within Singapore, SingPost offers services for letters, small packages and larger parcels. Options include Basic Mail, Registered Service, Tracked Letterbox and Speedpost Standard. Tracking availability depends on the product: Basic Mail is generally untracked, while Registered Service, smartpac, Tracked Letterbox and Speedpost services provide trackable shipment options.
Internationally, SingPost provides ordinary airmail and surface-mail options as well as Registered Service and the Speedpost International range. Speedpost includes Express, Priority, Saver and Economy services for different combinations of speed and cost. SingPost also provides business logistics services such as warehousing, fulfilment, cross-border eCommerce processing and distribution.
Readers can Track Singapore Post packages on 4Tracking by entering the shipment's tracking number into the tracking field. 4Tracking can identify many carriers automatically, or you can select Singapore Post manually when necessary. As a secondary option, SingPost provides its own Track Item tool and mobile app for checking supported mail and package tracking updates.
How Singapore Post shipment tracking works
Singapore Post Tracking uses the unique identifier assigned to a trackable mail item or parcel. SingPost states that the tracking number can usually be found on the receipt or consignment note issued when the item is sent. For smartpac shipments, the tracking number is printed on the product itself.
After the number is entered, available shipment events can show progress through the postal or courier network. SingPost specifically notes that Registered Service tracking reflects major milestones rather than providing a detailed scan at every stage, so a period without a new event does not automatically mean that the shipment has stopped moving.
Tracking is available for smartpac, Registered Service and all Speedpost services. Some ordinary postal products do not include tracking. If the sender selected an untracked service, entering the address, order number or recipient name will not create package tracking information because a valid carrier-issued tracking number is required.
How to Track a Singapore Post package on 4Tracking
Copy the complete tracking number from the shipping confirmation, receipt, consignment note or parcel label and enter it on 4Tracking. Allow automatic carrier detection to identify Singapore Post, or choose Singapore Post manually if necessary. Keep every letter and digit exactly as provided because changing the prefix, suffix or number sequence can prevent the shipment from being recognized.
Singapore Post tracking number formats
Singapore Post uses more than one tracking-number format, so there is no single public pattern that should be applied to every SingPost service. The carrier's official tracking guidance provides examples including SM000000001SG and RA000000001SG, illustrating that different products may use different prefixes while retaining the SG country suffix in these examples.
Registered Service has a clearly documented format. SingPost states that Registered Service items posted from Singapore receive a tracking number beginning with RA, followed by nine digits and ending with SG. An official example is RA123456789SG. This format applies to applicable Registered Service items sent locally within Singapore and Registered Service items posted from Singapore to overseas destinations.
SingPost also gives SM000000001SG as an example when explaining how customers can check mail or package status. However, the carrier does not state on that support page that every smartpac or other tracked shipment must use one fixed SM pattern. It is therefore best to use the exact identifier printed on your shipment rather than changing a number to resemble an example.
Incoming international registered items can have formats assigned by the foreign postal administration. SingPost specifically warns that foreign Registered Service numbers may use different formats. A package arriving in Singapore from another country therefore should not be expected to begin with RA or end in SG simply because SingPost performs the final delivery.
Singapore Post delivery times within Singapore
Delivery time depends on the selected service. SingPost currently lists Speedpost Standard as a tracked domestic service with delivery in 1 working day. Tracked Letterbox is listed at 2 working days, while Registered Service within Singapore is also listed at 2 working days.
For example, a qualifying parcel sent using Speedpost Standard follows a published 1-working-day delivery standard, whereas a small item using Tracked Letterbox follows a 2-working-day standard. These timeframes apply to their respective services and should not be treated as interchangeable promises for every SingPost shipment.
SingPost's Quality of Service standards also distinguish letters from other postal items. Local Basic Letters are targeted for delivery by the next or second working day, while packages, publications and similar items under the cited postal standard have a delivery standard of 3 working days. Working days generally refer to Monday through Friday excluding public holidays for these standards.
Singapore Post international delivery times
International transit varies considerably by destination and service. SingPost publishes broad estimates for its Speedpost International products rather than one worldwide delivery time. Speedpost Express International is estimated at 2 to 9 working days to major cities, while Speedpost Priority International is estimated at 3 to 14 working days.
Speedpost Saver International is listed at approximately 3 to 11 working days, while the slower Speedpost Economy International service has an estimated transit of 3 to 15 weeks. SingPost states that these estimates are indicative for major cities and that actual transit times can differ according to the destination.
As an example, choosing Express rather than Economy can change the published expectation from a matter of working days to potentially several weeks. The exact delivery time for a shipment between Singapore and destinations such as China, Japan or New Zealand should therefore be checked using SingPost's current rate and delivery calculator for the specific destination and service rather than assuming the broadest international estimate applies.
International delivery can also be affected by flight availability, customs clearance, destination-country procedures, local holidays and the delivery standards of overseas postal or logistics partners. These factors can create periods without visible Tracking updates even while a package remains in transit.
Why Singapore Post Tracking may not update
A missing update can have several explanations. Registered Service only displays major tracking milestones, so the item may move between facilities without generating a detailed public scan. Overseas shipments may also be travelling between postal administrations, waiting for transport or undergoing customs processing.
If a shipment was sent using a service without tracking, detailed online events will not become available later. SingPost identifies Basic Mail and certain ordinary international mail options as services where Tracking is not provided. Ask the sender which product was used if you were expecting a tracking number but did not receive one.
What to do if a Singapore Post package has a delivery problem
If the tracking number is not recognized, first check it against the receipt, consignment note or shipping confirmation and make sure the complete identifier was entered. If the number is correct but the shipment still cannot be found, use SingPost's online enquiry form or contact customer service for assistance.
Singapore Post lists 1605 as its customer-service hotline for callers in Singapore and +65 6845 4545 for callers from overseas. Published support hours are Monday to Friday from 8:30 am to 6:00 pm and Saturday from 8:30 am to 1:00 pm, with the service closed on Sundays and public holidays.
The official online enquiry form can be used for delivery issues, shipment status questions and redelivery requests. When filing an enquiry or claim for a lost or damaged item, SingPost asks customers to provide information such as the tracking number, sender and recipient details, and a description of the item and its value. Keep receipts, photographs and other relevant shipment records when reporting damage or loss.
If a delivery notification card was left, follow the instructions printed on it or check the latest tracking status. SingPost states that an item transferred to a post office after an unsuccessful delivery is generally held for collection for 10 working days before being returned to the sender if it remains uncollected.
Frequently asked questions about Singapore Post package tracking issues
Why is my Singapore Post tracking number not working?
Make sure you entered the complete number exactly as shown on the receipt, consignment note or shipping label. A wrong or incomplete number can prevent Tracking from finding the shipment. Also confirm that the sender used a trackable service, since Basic Mail and some ordinary international services do not provide tracking.
What does a Singapore Post tracking number look like?
The format depends on the service. SingPost gives RA123456789SG as an official Registered Service example, consisting of RA, nine digits and SG. Its general tracking guidance also shows SM000000001SG as another example, but customers should always use the exact identifier issued for their own shipment.
Do all Singapore Post tracking numbers end in SG?
No. Singapore-originated examples such as RA123456789SG and SM000000001SG use the SG suffix, but incoming international items can carry numbers assigned by foreign postal operators. SingPost specifically states that foreign Registered Service numbers may use different formats.
How long does Singapore Post take to deliver within Singapore?
The service determines the timeframe. Speedpost Standard is listed at 1 working day, while Tracked Letterbox and Registered Service are listed at 2 working days. Other mail and package products have their own delivery standards.
How long does Singapore Post international delivery take?
Speedpost Express International is estimated at 2 to 9 working days to major cities, Priority at 3 to 14 working days, Saver at 3 to 11 working days and Economy at 3 to 15 weeks. Actual transit depends on the destination and service, so SingPost recommends checking the specific shipment through its rate calculator.
Why has my overseas Singapore Post Tracking stopped updating?
An overseas item can spend time in international transport, customs processing or another postal operator's network before the next visible event. Registered Service also records major milestones rather than every movement. A gap between scans therefore does not by itself confirm that the package is lost.
Can I Track Singapore Post packages on 4Tracking?
Yes. Enter the SingPost tracking number on 4Tracking to see available package tracking events. Automatic carrier detection can identify many shipments, and you can select Singapore Post manually if necessary.
What happens if I miss a Singapore Post delivery?
Check the delivery notification card or the latest online Tracking status. SingPost may schedule another delivery, often on the next working day in applicable cases, or transfer the item to a nearby post office. Items held at a post office are generally available for collection for 10 working days.
What should I do if my Singapore Post package is marked delivered but I cannot find it?
Check your letterbox, doorstep and delivery information first, depending on the service used. If the package still cannot be located, submit a delivery enquiry to SingPost or call 1605 in Singapore or +65 6845 4545 from overseas and provide the tracking number.
How do I report a lost or damaged Singapore Post package?
Use SingPost's official online enquiry form or contact its customer-service hotline. Provide the tracking number, sender and recipient information, item description and value, and retain photographs, receipts and other evidence that may support the enquiry or claim.
