RSTU Container Prefix Owner

RSTU is a container owner code associated with Unit45 BV. Learn how BIC container prefixes identify equipment owners and operators.

Prefix: RSTU
Owner or operator: Unit45 BV

The four-letter prefix RSTU appears at the start of ISO container identification numbers and is associated with Unit45 BV.

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.

Who uses RSTU containers

RSTU is registered to Unit45 BV. Leased or exchanged equipment can move with a different shipping line, so the prefix alone does not identify the carrier of a shipment.
