How long is the TWIC card valid?
TWICs remain valid for five years, unless the expiration date was based on a comparable credential (Free and Secure Trade (FAST) card, Merchant Mariner Document/ License, or Hazmat Endorsement). The expiration date is displayed on the face of the TWIC. TWIC holders are responsible for knowing when to begin the renewal process. For individuals who pay the reduced fee, the expiration date of their TWIC will be five years from the date listed on the credential associated with the comparable security threat assessment.
