TSA provides users with a Canceled Card List and Visual Canceled Card List. The Canceled Card List provides the Federal Agency Smart Credential Numbers (FASC-Ns) of canceled cards. The Visual Canceled Card List provides the Credential Identification Numbers (CINs) of canceled cards.
When security officials cannot visually inspect a card’s Federal Agency Smart Credential Numbers, they commonly use the Canceled Card List in physical access control solutions or readers in which the TWIC® card is electronically inspected to manage access control. Credential Identification Numbers are visibly printed on the front and/or back of the TWIC® card, and security officials may use the Visual Canceled Card List to support visual inspection of TWIC® cards.
