What do International Intermodal Containers look like?

Traxa is currently designed to capture only international intermodal containers to allow for use all over the world. There are many types of intermodal containers including domestic, refrigerated, and even trailers; however, Traxa is currently focused on capturing and tracking the international intermodal container market.

Each international intermodal container is allocated a standardized ISO 6346 reporting mark (ownership code). Look for:

  1. Four letters long ending in either U, J, or Z
  2. Followed by six digits
  3. Finally, a check digit, which is always inside of a box.
