Container number checker.
Check one container number or a whole list against the ISO 6346 check digit. Catch typos before they reach the bill of lading.
Common questions
- How do I know if a container number is valid?
- Its last digit must match the check digit calculated from the first ten characters (ISO 6346). Paste the number above and the checker does the calculation.
- Does a valid check digit mean the container exists?
- No. It only proves the number is well formed. Always compare container numbers across the SI, VGM and booking too.
- Can I check many container numbers at once?
- Yes. Paste a whole column from Excel, one number per line, up to 500 at a time.
