Romocean container tracking

How to read a Romocean container number

ROMJ4032785 example only — not a real shipment

Container numbers follow ISO 6346, the international standard for freight-container identification: four letters, six serial digits, then one check digit. The first three letters are the owner code — registered with the BIC (Bureau International des Containers) — and the fourth letter is the equipment category (U for a standard freight container).

Take ROMJ4032785 as a Romocean-style example: ROMJ is the registered prefix (owner code ROM plus the category letter J), 403278 is the serial, and the final 5 is the check digit computed from the ten characters before it — tracking systems use it to catch typos before they search.

If your Romocean tracking isn’t working

1. 1 Check the number format first

   Container numbers are exactly four letters plus seven digits (like ROMJ4032785). A common slip is confusing the letter O with zero, or dropping the final check digit. Copy the number from the door of the container or your booking confirmation rather than retyping it.

2. 2 Make sure the number was issued by this carrier

   If your shipment was booked through a freight forwarder, the number on your paperwork may be the forwarder’s own reference, which Romocean’s system won’t recognise. Ask whoever issued your documents which carrier number to use — or paste the number on our homepage and we’ll work out who it belongs to.

3. 3 Too early or too late

   Timing matters: a number that was only just issued may not show results yet, and carriers remove old shipments from public tracking a few weeks after delivery. If the shipment is very new or long delivered, an empty result doesn’t mean the number is wrong.

4. 4 Paste carefully on Romocean’s page

   Romocean asks you to type the number on its own page, so paste it exactly — no spaces before or after, and no extra characters picked up from an email. If the page shows a security check, complete it and search again.

5. 5 Still nothing?

   Contact whoever sold you the freight service (your forwarder, broker, or Romocean directly) with the container number and the booking reference — they can see internal status that public tracking doesn’t show.

Frequently asked questions

How do I track a Romocean container?

Type your container number in the box above and press Track. You’ll land on Romocean’s own tracking page — paste your number there and search. Romocean container numbers usually begin with ROMJ, ROMU, ROMZ.

What does a Romocean container number look like?

Container numbers follow the ISO 6346 standard: four letters then seven digits (for example CSNU1234567). The first four letters identify the owner. For Romocean the owner prefixes are typically one of ROMJ, ROMU, ROMZ. A format-valid example is ROMJ4032785.

Why does the Romocean page open without my number filled in?

Romocean asks everyone to enter the number on its own page (it has a security check), so it can’t be filled in ahead of time. We bring you to the right page — just paste your number there.

What if my number doesn’t start with ROMJ or ROMU?

Then it probably wasn’t issued by Romocean — shipments booked through a freight forwarder or partner carrier often travel under another company’s container number. Paste the number on our homepage and we’ll suggest the right shipping line, or check your shipping paperwork for who issued it.

Is this Romocean’s official tracking site?

No — this is a free, independent tool that brings every carrier’s tracking together in one place. When you track here you end up on Romocean’s own page, so everything you see comes straight from Romocean. We never see or store your shipment details.
