OOLU Container Prefix Owner

OOLU is a container owner code associated with OOCL. Learn how BIC container prefixes identify equipment owners and operators.

Prefix: OOLU
Owner or operator: OOCL

The four-letter prefix OOLU appears at the start of ISO container identification numbers and is associated with OOCL.

A complete container number combines the owner prefix, six-digit serial number, and check digit. The prefix identifies registered equipment ownership and does not always identify the carrier currently transporting the container.

Use the CargoEnter container validator to check the number structure before starting shipment tracking.

OOLU container number format

A container number starting with OOLU has the four-letter prefix, a six-digit serial number, and one check digit, for example OOLU1234567.

Who uses OOLU containers

OOLU is registered to OOCL. Leased or exchanged equipment can move with a different shipping line, so the prefix alone does not identify the carrier of a shipment.
