The National Maritime Center issued a bulletin September 7 as a reminder that in accordance with federal regulations, duplicate Merchant Mariner Credentials may be issued free of charge to mariners whose credentials were lost or destroyed as a result of hurricane Harvey or Irma. Mariners should follow the steps below to obtain an expedited replacement credential:

• Provide a statement of loss to the National Maritime Center (NMC) via fax at 1-304-433-3412, via e-mail at, or by calling 1-888-IASKNMC (1-888-427-5662). The statement should contain the following:

Unless otherwise requested, any duplicate MMCs issued per the request process above will include a corresponding Medical Certificate, if previously issued. We will make every effort to have duplicate credentials mailed out the next business day. Alternatively, mariners may submit form CG-719B, Application for Merchant Mariner Credential, to one of the Regional Exam Centers with the information above. If your credential is unserviceable due to damage or your lost
credential is subsequently found, that credential should be mailed to the NMC.

Mariners should also be aware that Regional Exam Centers in affected regions may be closed or operating at a reduced capacity. Be sure to check NMC’s website for the latest information on closures and instructions for submitted applications.
