Dalreftrans container tracking

How to read a Dalreftrans container number

DLTJ5957385 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 DLTJ5957385 as a Dalreftrans-style example: DLTJ is the registered prefix (owner code DLT plus the category letter J), 595738 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 Dalreftrans tracking isn’t working

1. 1 Check the number format first

   Container numbers are exactly four letters plus seven digits (like DLTJ5957385). 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 Dalreftrans’ 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 Still nothing?

   Contact whoever sold you the freight service (your forwarder, broker, or Dalreftrans 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 Dalreftrans container?

Type your container number in the box above and press Track. You’ll land on Dalreftrans’ own tracking page with your number already filled in. Dalreftrans container numbers usually begin with DLTJ, DLTU, DLTZ.

Can I bookmark or share my Dalreftrans tracking link?

Yes — once your shipment comes up on Dalreftrans’ page, you can bookmark that page or send the link to a colleague, and they’ll see the same shipment.

What if my number doesn’t start with DLTJ or DLTU?

Then it probably wasn’t issued by Dalreftrans — 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 Dalreftrans’ 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 Dalreftrans’ own page, so everything you see comes straight from Dalreftrans. We never see or store your shipment details.
