The four-letter prefix WTLU appears at the start of ISO container identification numbers and is associated with White Line Shipping.
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.
WTLU container number format
A container number starting with WTLU has the four-letter prefix, a six-digit serial number, and one check digit, for example WTLU1234567.
Who uses WTLU containers
WTLU is registered to White Line Shipping. Leased or exchanged equipment can move with a different shipping line, so the prefix alone does not identify the carrier of a shipment.
