Sendle is a parcel delivery and shipping service operating in Australia, Canada and the United States, with services designed particularly for small businesses, online sellers and people who want to book deliveries online. Customers can create shipments through the Sendle platform, print shipping labels, arrange eligible pickups or use available drop-off locations, and follow packages through Tracking updates.
Sendle offers domestic package delivery within its operating markets, with service choices that vary by country, route and parcel requirements. Depending on the market, these include standard delivery as well as faster options such as Sendle Express in Australia and Canada and time-specific services in the United States.
International and cross-border shipping is also available on supported routes. Sendle Australia offers international shipping to numerous destinations, Sendle Canada supports cross-border shipping to the United States, and Sendle's U.S. service includes international shipping options. Availability, parcel limits and delivery estimates depend on the origin, destination and service selected when the shipment is booked.
Sendle works with delivery partners as part of its shipping network, so a package may be handled by different operators during its journey. Sendle provides a central booking and package tracking experience, allowing senders and receivers to follow available scans without needing to identify every delivery partner involved in advance.
How Sendle shipment tracking works
Every Sendle package receives a unique Sendle Reference and a tracking link. Tracking events can include pickup, drop-off, in transit, out for delivery, delivery attempted, local delivery and delivered updates. Depending on the shipment, the tracking page may also show information from a delivery partner handling part of the journey.
To Track a Sendle package with 4Tracking, enter the Sendle Reference in the tracking field. 4Tracking can automatically detect supported carriers from the number; you can also choose Sendle manually when necessary. Press the Track button to open the results page and see the latest available package tracking events.
Senders can also follow shipments from their Sendle dashboard. Receivers can use the Sendle tracking page with the reference supplied by the sender, while email Tracking notifications may be sent when the receiver's email address was included in the booking.
Sendle tracking number formats
The primary public package tracking identifier is called the Sendle Reference. Sendle's official developer documentation describes it as an alphanumeric reference that always begins with the letter S. Official examples include S3ND73, S34WER4S and S7BFWKC9BI.
Sendle's official resources currently differ slightly on the stated reference length. Its developer glossary describes Sendle References as 6 to 10 alphanumeric characters, while its U.S. tracking page describes tracking numbers as 6 to 8 characters. Because official examples include different lengths, the safest approach is to use the complete Sendle Reference exactly as provided in the shipment email, label information or order details rather than assuming a single fixed length.
Do not confuse the public Sendle Reference with an internal order ID or a merchant's own order number. The Sendle Reference beginning with S is the identifier intended for public Tracking.
Sendle delivery times and examples
Sendle calculates a delivery estimate for individual bookings based on the route and service. The estimate can be viewed during booking and later on the Sendle dashboard or tracking page. Standard delivery estimates should generally be treated as estimates rather than guaranteed arrival dates unless the shipment was booked under a service that specifically includes a delivery guarantee.
In Australia, Sendle Express provides 2-business-day delivery after pickup for eligible shipments. Sendle states that eligible Express bookings made before 12 PM can receive same-day pickup. For international shipments sent from Australia, published examples include approximately 4–11 business days to New Zealand, 8–14 business days to the United States and 11–18 business days to Canada.
In Canada, Sendle Express is a domestic pickup-only service with an estimated delivery time of 1–2 business days from the first pickup scan. Sendle notes that the Express ETA in Canada is not guaranteed.
In the United States, Sendle offers specific faster services including Sendle 2-Day Guaranteed and Sendle 3-Day Guaranteed. Their delivery periods are measured from the first qualifying pickup or drop-off scan, with the respective guarantee covering delivery within two or three business days under the applicable service conditions.
Actual shipment progress can still be affected by the selected service, pickup timing, weekends and public holidays, destination accessibility, delivery-partner operations and, for international packages, customs processing. Check the delivery estimate attached to the specific shipment rather than applying one timeframe to every Sendle package.
How to contact Sendle about shipment issues
Sendle encourages customers with delivery problems to use the Sendle Toolbox available through the package tracking page or their account dashboard. Depending on the situation and market, these tools can be used to manage a delivery, arrange a redelivery, report a late package or start a shipment investigation.
Sendle also provides support through its official Help Centre and contact pages. Official support information for Australia and Canada lists chat support available 24 hours a day, seven days a week, as well as a contact form for email enquiries. Sendle states that email responses are generally provided within two business days. Australia additionally lists a callback option for account holders during its published weekday callback hours.
If your package is late, Sendle's support guidance recommends checking the shipment's estimated delivery date and Tracking first. In its Australia, Canada and U.S. support documentation, Sendle advises treating a package as potentially late when more than two business days have passed beyond the delivery estimate without an appropriate update. At that point, use the package's management tools or contact support with the Sendle Reference ready.
Frequently asked questions about Sendle package tracking issues
Why is my Sendle tracking number not working?
Check that you entered the complete Sendle Reference and that it begins with S. A newly booked shipment may also have limited Tracking information until the first pickup, drop-off or network scan occurs. If the number still produces no result, confirm the reference with the sender.
What does a Sendle tracking number look like?
A Sendle Reference is alphanumeric and begins with S. Official examples include S3ND73, S34WER4S and S7BFWKC9BI. Sendle's official resources show references of different lengths, so use the complete assigned reference rather than trimming it to a particular length.
Why has my Sendle package tracking stopped updating?
Tracking can pause between scans while a package is travelling between facilities or being handled by a delivery partner. International shipments can have longer gaps, and Sendle notes that some destinations provide less complete tracking after a package enters the local postal or delivery network.
What does Local Delivery mean in Sendle Tracking?
Sendle uses the Local Delivery tracking event when a shipment is being handled by a local delivery partner, such as a postal operator or another last-mile service. Further scans may come from that partner as the package approaches delivery.
My Sendle package is more than two business days past its estimate. What should I do?
Open the package tracking page and review the latest scan first. If more than two business days have passed beyond the estimated delivery date without a useful update, use the Sendle Toolbox to report the problem or start an investigation, or contact Sendle through its official support channels.
Can I Track a Sendle package without having an account?
Yes. A receiver can use the Sendle Reference on the public tracking page without needing the sender's dashboard account. You can also enter the Sendle Reference on 4Tracking to follow supported shipment updates.
Where can I find my Sendle Reference?
The Sendle Reference is provided with the shipment's tracking information and can appear in confirmation or notification emails. If you are receiving a package and were not given the reference, ask the sender or retailer that booked the Sendle shipment.
Why does my international Sendle package have another tracking number?
An international package may receive a local reference when it enters another postal or delivery network. Sendle advises using the local reference shown on the tracking page when contacting the destination country's postal or customs authority about that stage of the shipment.
What should I do if a Sendle package could not be delivered?
Check the latest package tracking event and open the management options available for the shipment. Depending on the delivery and location, the Sendle Toolbox may provide options related to redelivery or further investigation. If no suitable option appears, contact Sendle support with the Sendle Reference and delivery details.
