The four-letter prefix WSLU appears at the start of ISO container identification numbers and is associated with Westwood Shipping Lines.
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.
WSLU container number format
A container number starting with WSLU has the four-letter prefix, a six-digit serial number, and one check digit, for example WSLU1234567.
Who uses WSLU containers
WSLU is registered to Westwood Shipping Lines. Leased or exchanged equipment can move with a different shipping line, so the prefix alone does not identify the carrier of a shipment.
