Tank Container numbering system

Question:  “ISO Tanks are assigned a six-digit serial numbers by an international body. Can we label a tank with a different serial number?  The six-digit serial number remains on the tank.  For example, we have a tank with a serial number 117003.  We labeled the tank as AH-1.  This is how the tank is identified on a BOL.  Is this authorized?  Can we do this legally?” 

Tank Guru:  Absolutely, provided you are talking about transportation domestically.  If the tank were traveling internationally and going on a container ship, you would want to refer to it by the container number (the six digits you refer to above, preceded by the 4 alpha characters and then followed by the check-digit).  For more information on that numbering system, please see this link:  https://www.bic-code.org/bic-codes/

But if the tank stays on a chassis and you’re just referring to trucking the tank container from A to B, then you can call it whatever you want on the BOL.  Hope that helps.  Great question!
