CodeISO 6346Issued byISOFieldContainers
What it covers
- Owner code (3 letters) + equipment category (U for freight containers) + 6-digit serial + 1 check digit.
- Size and type codes and operational markings.
Key points for fabricators
- The check digit is calculated from the other 10 characters – a typing error is detected immediately.
- Size-type codes: 22G1 = 20' general purpose, 42G1 = 40' GP, 45G1 = 40' high cube.
How PEB Studio supports it
Container numbers are validated against the ISO 6346 check digit in the PKL editor and the container packing report shows the size-type code.
