Samudera Shipping container tracking

How to read a Samudera Shipping container number

SIKJ7119037 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 SIKJ7119037 as a Samudera Shipping-style example: SIKJ is the registered prefix (owner code SIK plus the category letter J), 711903 is the serial, and the final 7 is the check digit computed from the ten characters before it — tracking systems use it to catch typos before they search.

If your Samudera Shipping tracking isn’t working

1. 1 Check the number format first

   Container numbers are exactly four letters plus seven digits (like SIKJ7119037). 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 Samudera Shipping’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

   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 Samudera Shipping’s page

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

What if my number doesn’t start with SIKJ or SIKU?

Then it probably wasn’t issued by Samudera Shipping — shipments booked through a freight forwarder or partner carrier often travel under another company’s container number.

Is this Samudera Shipping’s official tracking site?
