Who uses MRKU containers
MRKU is registered to MAERSK A/S. Registration identifies the prefix holder; it does not establish which shipping line carries a particular shipment. Use the carrier named on your booking or bill of lading.
Check the number before you search
Every container number ends in a check digit calculated from the first ten characters (ISO 6346). If a MRKU number returns no result, run it through the checker on this page first: a mistyped letter or digit can cause a lookup to fail.
Read the status, not just the ETA
Carrier tracking shows estimated and actual events. A discharge at a transshipment port is not arrival at your destination, and discharged is not the same as released for collection. Confirm customs and terminal release before booking a haulier.
How CargoFlowPlus handles it
- Check the number: Paste the container number to confirm the format and check digit before you search anywhere.
- Use the carrier on your documents: Track with the shipping line on your booking or bill of lading, not with the box owner alone.
- Watch free time, not only the ETA: In CargoFlowPlus, follow ETA changes, discharge and the days left before demurrage or detention.
Which shipping line uses the MRKU prefix?
MRKU is registered to Maersk. The prefix identifies its registered owner; the shipping line on your booking or bill of lading is the one that reports its movements.
Why does my MRKU container show no tracking result?
First confirm the check digit with the container number checker. If the number is valid, search with the carrier named on your documents, or use the booking or bill of lading number instead; very new bookings and returned empties may not appear yet.
