Hapag-Lloyd container prefixes

Track on hapag-lloyd.com — official Hapag-Lloyd tracker

Full Hapag-Lloyd container tracking guide →

HLCU, HLXU, HLBU, UACU, UAEU and HAMU are the BIC owner prefixes registered to Hapag-Lloyd. A container number that starts with any of them belongs to the Hapag-Lloyd fleet and is tracked free at hapag-lloyd.com. The eleventh character of the number is a check digit; it is worked out below for each prefix.

Hapag-Lloyd, headquartered in Hamburg, is Europe’s second carrier and the product of a long line of mergers — most recently the 2017 absorption of the Gulf line UASC.

The UASC deal is visible in the register to this day: two ex-UASC codes still circulate alongside the four Hamburg-registered ones, all served by the hapag-lloyd.com tracker.

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 Hapag-Lloyd 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 HLCU, HLXU and HLBU containers?

Hapag-Lloyd does, a shipping line founded in 1970 — the BIC register lists 6 owner prefixes under it: HLCU, HLXU, HLBU, UACU, UAEU and HAMU.

How do I track a HLCU container?

Free, on the official Hapag-Lloyd tracker at hapag-lloyd.com — paste the full 11-character number; no account is needed. The same tracker serves all 6 Hapag-Lloyd prefixes.

Why does Hapag-Lloyd have 6 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 6 are tracked on the same hapag-lloyd.com system.

Is HLCU a shipping line prefix or a leasing prefix?

A shipping line prefix — Hapag-Lloyd both owns the box and moves it, so the owner and the tracker are the same company.

Is HLCU2466254 a valid container number?

Yes — HLCU 246625-4 passes the ISO 6346 check: the weighted sum for HLCU246625 leaves a remainder of 4 when divided by 11, which gives check digit 4. It is an example computed for this page, not a box we have seen.

One page, every owner code

Know whose box it is before you search

All 85 owner prefixes mapped to their line or leasing company, with the leased ones marked — so you can tell at a glance when to track with the line instead. Container dimensions are on page two.
