To track a Wan Hai shipment, enter your bill of lading, container number, booking number, or release number into the Cargo Tracking Inquiries page on Wan Hai Line's official site. Container numbers follow the WHLU1234567 format, and the portal keeps tracking data for 90 days. You get milestone events, a carrier ETA, and the voyage details needed for documentation and customs.
That covers the paperwork. Wan Hai tracking goes further when you add AIS-based vessel tracking on top of the carrier portal. AIS tools show you where the ship is right now, how fast it's moving, and whether the schedule is actually holding: none of that appears in any carrier's milestone view.
What Is Wan Hai Line?
Wan Hai Lines is a fully containerized shipping company incorporated in 1965 and headquartered in Taipei, Taiwan. The carrier ranked 11th in the world in the Alphaliner Top 100 of 14 October 2026, with 633,064 TEU across 125 ships and another 48 vessels on order, placing it alongside Evergreen and Yang Ming as one of the major Asian container lines.
Its network spans Asia, the Middle East, India, the Red Sea, the United States, and South America. The core business is intra-Asia liner service, supplemented by selected long-haul routes connecting East Asia to the Middle East and the Americas. The fleet mixes feeder vessels with larger ships suited to the short, high-frequency lanes that link Southeast Asian ports.
Intra-Asia schedules run tightly. A single congested port call can cascade delays across several consecutive stops. That's why shippers using Wan Hai often need visibility between ports, not only confirmation of what happened at each terminal.
How Does Wan Hai Container Tracking Work?
Wan Hai's Cargo Tracking Inquiries page is built around shipment references. It accepts a booking or B/L number, a container number, or a release number, and several can be entered at once to trace multiple shipments. All of them link to the same shipment record, so use whichever your freight forwarder provided. If you need to know what your B/L number refers to, this guide to the bill of lading explains each field.
Data the portal returns
Once you enter a reference, the Wan Hai tracking portal returns:
- Current cargo status: in port, loaded, in transit, or discharged
- Vessel name and voyage number
- Route: origin port, intermediate stops, and destination
- Carrier ETA at the destination port
- Event history: gate-in, loaded on vessel, departure, arrival, and gate-out
- Container details: depot information, seal number, and weight
For customs filings and invoicing, that covers what you need. Records older than 90 days are no longer shown, so for an older shipment ask your local Wan Hai office.
How to Check a Wan Hai Schedule Port to Port
Wan Hai's site has three schedule tools under Shipping Schedule. Point-to-Point takes an origin and a destination port and lists the sailings between them with departure and arrival dates. Vessel Tracking takes a vessel name and returns its port rotation: each port with arrival voyage, ETA, berthing time (ETB), departure voyage, ETD, and status. Services and Service Route show the same schedules grouped by liner service. Wan Hai also lists Email Schedule Tracking and Email Cargo Tracking for getting schedules and cargo status by email rather than by repeated lookups.
Despite the name, Vessel Tracking is a schedule, not a map: it shows where the ship is planned to call, not where it is now. Wan Hai notes that the estimated schedule is for reference only and may change without notice. For checking sailings across several carriers at once, this guide to vessel schedules covers the common tools.
Where Wan Hai Tracking Falls Short
The portal's data is event-based. It records what has already happened at ports and terminals. Between those port events, it shows nothing about what the vessel is actually doing.
There's no live map. There's no speed or course indicator. The carrier ETA updates only when a new terminal event is logged or the schedule is recalculated internally, which can leave the number stale for days during a disruption. If the vessel is slowing through heavy swells east of the Philippines, or waiting at anchorage outside a congested port, none of that appears in the milestone timeline until a terminal records the next cargo event.
Weather context is absent too. For a shipper managing reefer cargo or a tight delivery window, a vessel pitching through a storm isn't going to make its scheduled ETA, but the carrier portal won't say so until the revised ETA posts.
The email services carry the same limit. They pass on what the carrier has recorded or scheduled, so a ship that is running 12 hours behind at sea shows up only once the schedule is revised.
This isn't unique to Wan Hai. Carrier portals across the industry are built for documentation workflows, not real-time monitoring.
How to Track Wan Hai Vessels with AIS
AIS (Automatic Identification System) is a mandatory transponder system on most commercial vessels under SOLAS regulations. Each vessel broadcasts its identity, position, speed, course, navigation status, and ETA continuously. Terrestrial receivers cover coastal zones; satellites extend that coverage across open ocean with position updates every few minutes.
Every Wan Hai containership in service transmits AIS data. AIS-based tracking platforms aggregate that stream and let you search by vessel name. You can pull up WAN HAI A07, see its live position on a map, and watch it move in near real time. For a deeper explanation of how the underlying system works, see this guide to AIS vessel tracking.
What AIS shows that the Wan Hai portal doesn't
- Live vessel position on an interactive map, updated continuously
- Current speed in knots and heading in degrees
- Navigation status: underway, at anchor, moored, or stopped
- AIS-broadcast ETA, recalculated as the vessel moves
- Historical track line showing the route already sailed
- Weather and sea conditions at the ship's current location
The practical workflow is to use both sources together. Use the Wan Hai portal to confirm cargo milestone events: loading confirmation, departure date, and estimated arrival. Then use an AIS tool to watch the actual vessel. If your booking shows the container on WAN HAI A07, you can search that vessel in any AIS-based app and see whether it's 120 nautical miles off Busan making 16 knots, or drifting at anchorage because a berth isn't available.
A cargo event log says "in transit." AIS data tells you whether that transit is on time.
Choosing a Wan Hai Tracking Approach
Use the official Wan Hai portal when you need documented cargo milestones for customs or invoicing, container-level details like seal number and weight, or confirmation that a container loaded on a specific voyage. The portal is authoritative for those records, and it ties directly to your B/L or container reference.
Use an AIS-based tracking tool when you need to know where the vessel is right now, not just where it's been. If ETA slippage would affect downstream operations like warehouse scheduling, customs appointments, or customer commitments, you need the AIS layer to catch schedule risk before it surfaces as a missed event in the carrier portal.
Primo Nautic covers the AIS layer with AI-generated voyage updates, so the information arrives as plain-language insights rather than raw coordinates. Search for any Wan Hai vessel by name and the app shows its live position, current speed, ETA, and weather at the vessel's exact location. You can set arrival and departure alerts so you're notified when the ship itself moves, rather than when the carrier next updates its records.
Because Primo Nautic works across the full global AIS dataset, it handles any Wan Hai vessel on any route, and the same app works for every other carrier you ship with.
Understanding how container ship tracking works in the background helps you decide which data source to use at each stage of a shipment.
Tracking Wan Hai Vessels by Name
When your Wan Hai tracking result shows a vessel name, that name is your search term for AIS tracking. Most ships in the Wan Hai fleet carry the prefix "Wan Hai" followed by a number or letter series: Wan Hai 323, Wan Hai 516, WAN HAI A07. Some chartered vessels may appear under different names, so confirm the vessel name in your shipping documentation before searching.
AIS platforms resolve the name to an IMO or MMSI number and return the vessel's live track. If the name returns multiple results, use the IMO number from your B/L: every commercial ship keeps one permanent IMO number regardless of flag, owner, or name changes.
You can also search Primo Nautic by vessel name and then save the ship to your tracking list, which means future voyages for the same vessel are visible without a new search. For shippers who regularly move cargo on the same Wan Hai service, that persistent tracking saves a step every time a new booking arrives.
Conclusion
Wan Hai Line's official site is the right tool for cargo milestones and planned schedules: confirm that your container loaded, check the voyage details, and look up sailings port to port or by vessel. For live vessel visibility between port calls, AIS-based tracking fills the gap: real-time position, ETA that updates as conditions change, and alerts when something shifts.
Using both tools together gives you the complete picture: milestone confirmation from the Wan Hai portal and live intelligence from AIS data. Neither replaces the other; they answer different questions at different points in the shipment lifecycle.
