Providing Credentials to Mariners
Renewing A Merchant Mariner Credential
Welcome to the NMC renewal website. Here you will find
information in regards to renewing your license or what we now refer to
as a Merchant Mariner Credential. One of our most recent changes
is the requirements of all US Mariners to have a TWIC.
In order to avoid delays in obtaining your credential we have developed a checklist to help you complete this process. Please review the checklist to ensure that you do not miss or leave anything out of your application. Your application must be submitted (mailed) to a
REC and not to the National
Maritime Center.
Straight Renewal
If you are looking for a straight renewal then you are at the correct
website. Below you will find our Renewal Wizard to help guide you
