Merchant Mariner Credential Update

An update message from the National Maritime center is warning mariners that when they apply for Transportation Worker Identification Credential (TWIC), they must list their occupation as Merchant Mariner.

“Personal data supplied to TSA must match what is provided to the Coast Guard on the MMC application,” the notice said. “If a TWIC applicant does not list his or her occupation as Merchant Mariner, the Coast Guard cannot reconcile the data provided by the TSA. In such cases, mariners may be asked to work with TSA to update information, which could result in MMC application issuance delays.

To begin the application process for a TWIC, visit the TSA TWIC enrollment website: https://universalenroll.dhs.gov/programs/twic.
