What is the 5-digit alpha/numerical number?
My Global Entry card has the number SC... on the lower right corner of the front of the card. What is this number?
Best Answer
It appears to be a three-digit security code (similar to those used on bank cards) preceded by the letters "sc" for "security code." See, for example http://www.atnexus.com/nexuscard-activation.html.
The linked page concerns NEXUS cards, but image searches suggest that the numbering scheme for Global Entry cards is the same.
