Wan Hai Lines container prefixes: WHLU, WHSU
Track on wanhai.com — official Wan Hai Lines tracker
Full Wan Hai Lines container tracking guide →
WHLU and WHSU are the BIC owner prefixes registered to Wan Hai Lines. A container number that starts with any of them belongs to the Wan Hai Lines fleet and is tracked free at wanhai.com. The eleventh character of the number is a check digit; it is worked out below for each prefix.
Wan Hai Lines is the intra-Asia specialist out of Taipei — fewer headlines than the giants, but a dense short-sea network and rank eleven by capacity.
Two codes cover its containers and the wanhai.com cargo-track page reads both.
4 letters + 7 digits, printed on the doors. It is on your bill of lading too.
The answer appears as you type. Nothing is sent anywhere.

Can you see where the ship is?
Not from the container. A standard dry box has no power, no radio and no satellite receiver — it is a steel case with a number painted on it, and it reports nothing about itself. Every position you see against a Wan Hai Lines shipment was reported by something else: a terminal crane, a gate reader, or the ship.
A live map on a carrier’s tracking page is almost always plotting AIS, the transponder every large vessel broadcasts with its position, course and speed. That is genuinely useful at sea: it is a real position rather than a schedule, and an ETA recalculated from actual movement. It is also the ship’s position, not your box’s, and the two part company the moment the container is discharged.
On land the map goes quiet. Between the gate-out and the delivery there is no vessel to follow, and the road leg appears only as whatever events the terminal and the trucker report. A container sitting on a chassis in a yard shows the last position of a ship it left days ago. Only specialised IoT equipment reports its own location, and wherever that exists it is a paid product sold to the shipper, not something a tracking page gives away.
Frequently asked questions
Who owns WHLU and WHSU containers?
Wan Hai Lines does, a shipping line founded in 1965 — the BIC register lists 2 owner prefixes under it: WHLU and WHSU.
How do I track a WHLU container?
Free, on the official Wan Hai Lines tracker at wanhai.com — paste the full 11-character number; no account is needed. The same tracker serves all 2 Wan Hai Lines prefixes.
Why does Wan Hai Lines have 2 prefixes?
Because one prefix holds only a million serial numbers and a fleet outgrows it — and because a line that buys another line keeps the codes painted on the boxes it bought. All 2 are tracked on the same wanhai.com system.
Is WHLU a shipping line prefix or a leasing prefix?
A shipping line prefix — Wan Hai Lines both owns the box and moves it, so the owner and the tracker are the same company.
Is WHLU5857070 a valid container number?
Yes — WHLU 585707-0 passes the ISO 6346 check: the weighted sum for WHLU585707 leaves a remainder of 0 when divided by 11, which gives check digit 0. It is an example computed for this page, not a box we have seen.
