Macnels container tracking

How to read a Macnels container number

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).

The final digit is a check digit computed from the ten characters before it, so most typos are caught before a search even runs.

If your Macnels tracking isn’t working

1. 1 Check the number format first

   Container numbers are exactly four letters plus seven digits. 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 Macnels’ 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

   New shipments can take a little while to appear — most carriers only start returning results once the container is in their system after export gate-in or acceptance. Long-delivered shipments drop out too: tracking data is usually purged weeks or months after delivery.

4. 4 Paste carefully on Macnels’ page

   Macnels 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?

   Your booking agent or Macnels’ customer service can look the shipment up internally — have the container number and the issuing office or booking reference handy when you ask.

Frequently asked questions

How do I track a Macnels container?

Type your container number in the box above and press Track. You’ll land on Macnels’ own tracking page — paste your number there and search.

What does a Macnels 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.

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

Macnels 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.

Is this Macnels’ 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 Macnels’ own page, so everything you see comes straight from Macnels. We never see or store your shipment details.
