CNAU Container Prefix Owner

CNAU is a container owner code associated with Technic-France. Learn how BIC container prefixes identify equipment owners and operators.

Prefix: CNAU
Owner or operator: Technic-France

The four-letter prefix CNAU appears at the start of ISO container identification numbers and is associated with Technic-France.

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.

CNAU container number format

A container number starting with CNAU has the four-letter prefix, a six-digit serial number, and one check digit, for example CNAU1234567.

Who uses CNAU containers

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