11/14/2018: Merchant mariner credentials and TWIC enrollment

The National Maritime Center posted a bulletin to its website Nov. 13, 2018, to provide mariners with important information about Transportation Worker Identification Credential enrollment.

Mariners applying for a Merchant Mariner Credential (MMC) must list their occupation as merchant mariner on their TWIC applications. The Coast Guard relies on data provided by the Transportation Security Administration when evaluating MMC applications.

Personal data supplied to TSA must match what is provided to the Coast Guard on the MMC application. 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.
