DAI Post is an e-commerce parcel delivery company founded in Melbourne, Australia, in 2000. It specializes in international parcel logistics for online retailers and manages shipments moving through its own operations in Australia, the United Kingdom and the United States, while other stages of a shipment can involve airlines, customs authorities and delivery partners.
The company's services are built around cross-border e-commerce. DAI Post manages international inbound parcels, origin processing, air-freight coordination, customs clearance and final-mile delivery. Its official information describes a supply-chain model that gives the company greater control from its origin facilities through customs and onward delivery, supported by proprietary software for air freight, customs processing and final-mile management.
In Australia, DAI Post also provides last-mile delivery through its own network, which the company states reaches 100% of the Australian population. Depending on the shipment and destination, DAI Post can also work with subcontractors, postal organizations and other logistics providers to complete parts of the journey. This means a package may pass through several transportation stages even though its progress remains connected to the original DAI Post shipment record.
For recipients, package tracking is one of the main ways to follow these stages. DAI Post's Tracking system can show events from origin processing and international transport through arrival, customs clearance, local sorting, out-for-delivery status and final delivery. 4Tracking lets you Track DAI Post packages alongside shipments from other carriers from one tracking page.
How DAI Post shipment tracking works
DAI Post Tracking begins when shipment information is created and transmitted to the carrier. The first event can indicate that DAI Post has received the delivery details even before the physical parcel reaches an origin facility. Later scans can show acceptance, processing at the origin facility, international departure, arrival in a transit or destination country, customs processing, local sorting and delivery.
How to Track DAI Post packages with 4Tracking
Enter your complete DAI Post tracking number in the tracking field on 4Tracking. You can enter one number or multiple numbers when batch tracking is available. 4Tracking will attempt to detect DAI Post automatically; if necessary, select the carrier manually, press the Track button, and you will be redirected to the results page showing the latest available shipment events.
Tracking directly with DAI Post
DAI Post also provides its own online parcel Tracking page. Its official tracker supports up to 10 tracking numbers at one time. The tracking history can include timestamps and locations for major shipment stages, helping recipients see whether a parcel is still overseas, undergoing customs processing, moving within the destination network or already out for delivery.
Why can there be gaps between Tracking updates?
DAI Post explains that parcels are scanned at key points rather than continuously. A package can therefore still be moving even when no new public Tracking event appears. The carrier specifically notes that interstate and regional deliveries can sometimes show no new event for several days until the parcel reaches the next processing stage.
DAI Post tracking number formats
What does a DAI Post tracking number look like?
DAI Post's official Tracking system accepts shipment-specific tracking numbers. Current shipment records visible on its own website include 20-digit numeric identifiers such as 00393580940162753861 and 00393580940160830540. These are real format examples from the official DAI Post Tracking system.
Are all DAI Post tracking numbers exactly 20 digits?
DAI Post does not publish a current public specification stating that every shipment worldwide must use exactly the same 20-digit format. The official examples confirm that long numeric tracking numbers are in active use, but customers should not assume that every DAI Post service must follow one universal pattern. Use the complete number supplied by the retailer or sender.
Where can I find my DAI Post tracking number?
DAI Post advises recipients to check the order confirmation provided by the retailer. If the tracking number is not shown there, contact the retailer that shipped the order. The carrier states that a tracking number is required to monitor the parcel's movement.
DAI Post delivery times and supported examples
DAI Post does not publish one universal delivery-time promise that applies to every international parcel. Transit depends on the origin, destination, flight schedule, customs processing, local delivery route and any subcontractors or postal partners involved. DAI Post's service terms also state that standard delivery times are estimated rather than guaranteed.
Official shipment example from the United States to Australia
An official DAI Post Tracking record from July 2026 shows one parcel checked in at the company's Inwood, United States facility on July 16, departing internationally on July 17, arriving in Sydney on July 19 and being delivered in Sydney on July 22. This is an example of an actual tracked journey and should not be treated as a guaranteed six-day service standard for other packages.
Another United States to Australia shipment example
A separate official Tracking record shows a parcel checked in at Inwood on July 9, leaving the United States on July 11, arriving in Brisbane on July 14 and being delivered on July 16. The different timeline demonstrates why actual transit can vary even when the general origin and destination countries are similar.
United Kingdom origin example
DAI Post's official Tracking system also shows parcels processed through its London operation. One July 2026 shipment was checked in and processed in London on July 28 before departing by air on July 29 and continuing toward Australia. This confirms that international parcels can move through DAI Post's UK origin operation before entering destination-country processing.
Why can a DAI Post delivery take longer?
Tracking records can show departure delays, transit delays, trans-shipment through another country, customs processing and interstate transport after arrival. Each of these stages can add time to the journey. For that reason, use the expected-delivery information shown for your individual parcel when available rather than applying another shipment's transit time to your order.
How to contact DAI Post about shipment issues
DAI Post customer service email
DAI Post publishes consumercare@daipost.com for parcel and customer-service inquiries. Include the complete tracking number and a clear explanation of the issue so the support team can identify the shipment.
DAI Post customer service in Australia
For Australia, DAI Post publishes +61 3 8586 1200 as its customer-service telephone number. The carrier also provides an online contact form through daipost.com for customers who need help with a parcel delivery.
What if my shipment originated in the UK or the US?
DAI Post has confirmed own operations in the United Kingdom and the United States, but a current public consumer-support page with separate UK and US parcel-help telephone numbers could not be verified from the carrier's official website. For those shipments, use the DAI Post online contact form or consumercare@daipost.com unless the retailer has provided a more specific business support channel.
What information should I provide when asking for help?
Provide your DAI Post tracking number, retailer or sender name, delivery destination and the most recent Tracking status. If the parcel is being held by customs, DAI Post advises customers to contact its support team because Australian Border Force or the Department of Agriculture, Fisheries and Forestry may require additional information before the parcel can be released.
Frequently asked questions about DAI Post package tracking issues
Why is my DAI Post tracking number not working?
Check that the number was copied correctly from the retailer's order confirmation. If the shipment was only recently created, DAI Post may have received the electronic information before the physical package reached its network. If you cannot find a valid tracking number, DAI Post advises contacting the retailer that sent the parcel.
What format does a DAI Post tracking number use?
Official DAI Post Tracking records currently include 20-digit numeric numbers such as 00393580940162753861. However, DAI Post does not publicly state that every service must use exactly this format, so always use the identifier supplied for your individual shipment.
Why has my DAI Post Tracking stopped updating?
DAI Post scans packages at key stages rather than continuously. The carrier states that parcels can still be moving when no new event appears, especially during interstate or regional transportation. A new scan normally appears when the package reaches the next processing stage.
What does customs held mean on DAI Post Tracking?
DAI Post explains that a customs-held event can mean Australian Border Force or the Department of Agriculture, Fisheries and Forestry requires additional information before releasing the package. Contact DAI Post customer service to find out what information may be needed.
What does Authority To Leave mean?
Authority To Leave means that a signature is not required. If nobody answers when the driver arrives and the location is considered safe, the driver can leave the parcel there. If you need proof of an Authority To Leave delivery, DAI Post says you can submit an inquiry and request a copy.
What happens if it is not safe to leave my package?
DAI Post states that if nobody answers and the driver decides the parcel would be too exposed to leave safely, it can be taken to the nearest pickup location. The recipient should then receive a notification containing collection instructions.
How long will DAI Post hold my parcel at a pickup location?
DAI Post states that a package that has not been collected from a pickup location within seven days can be returned to its depot for return to the retailer. Follow the collection instructions promptly if Tracking indicates that the parcel is waiting for pickup.
Why did I not receive DAI Post delivery notifications?
DAI Post sends notifications for key shipment events when the retailer has supplied the recipient's email address and mobile phone number. If you receive no notifications, the carrier says it is likely that those contact details were not provided with the shipment.
Can DAI Post tell me the exact time my package will arrive?
DAI Post states that delivery times are determined by the driver's route and can change according to daily parcel volumes and traffic conditions. Track the shipment for the latest delivery status rather than relying on a fixed time of day.
What should I do if DAI Post says delivered but I cannot find my package?
Check the delivery location, any safe place around the address and the Tracking details first. If the parcel was delivered under Authority To Leave, you can request proof of delivery from DAI Post. If it still cannot be located, contact the carrier at consumercare@daipost.com or, in Australia, call +61 3 8586 1200.
Can I Track several DAI Post packages at once?
Yes. DAI Post's own Tracking page accepts up to 10 tracking numbers at one time. You can also use 4Tracking when multi-number tracking is available to follow several DAI Post packages together with shipments from other carriers.
