Logistics / Container tracking
Container tracking starts with a valid container number
Paste any container number below. We verify it against ISO 6346, identify the owning carrier from the prefix and tell you exactly where to look next — free, no account.
Free ISO 6346 check: we verify the container number, its check digit and the owning carrier before you waste time in a carrier portal. No account needed.
Carrier prefixes
The first three letters tell you which carrier owns the box — the fastest way to avoid searching in the wrong portal.
| Carrier | Common prefixes |
|---|---|
| MSC | MSCU, MEDU, MSDU |
| CMA CGM (incl. APL) | CMAU, CGMU, ECMU, APZU |
| Maersk / Hamburg Süd | MAEU, MRKU, MSKU, SUDU |
| Hapag-Lloyd | HLXU, HLCU, HLBU |
| COSCO / OOCL | COSU, OOLU |
| ONE | ONEU, NYKU, MOFU |
| Evergreen | EGHU, EGLV, EITU |
| HMM | HMMU, HDMU |
From one container to your whole book
A single lookup is fine. Forty open containers across five carriers is not: that is where the delays, demurrage invoices and “where is my box” emails come from. FocusFlow Logistics keeps every shipment in one dashboard with automatic milestones, ETA-change and delay alerts, client-facing status links and ISO 14083 / GLEC CO₂ per shipment for CSRD reporting.
