Shipping containers registered as HR have a separate domestic container number.

It might not have an R after it, but it's the same shape as H* plus the number eight.

You can use the website above to search for your domestic port number and enter it.

Put the shipping container in the left square and press the orange button.

In the image, you can see the number of domestic ports in red on the right-hand side.

I'm going to add a tour guide to the shipping container.
