CAXU Container Prefix Owner

CAXU is a container owner code associated with CAI International. Learn how BIC container prefixes identify equipment owners and operators.

Prefix: CAXU
Owner or operator: CAI International

The four-letter prefix CAXU appears at the start of ISO container identification numbers and is associated with CAI International.

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.
