Coast Guard National Maritime Center

Coast Guard National Maritime Center is located in Martinsburg, West Virginia in Berkeley County. The city is in the tip of the state’s Eastern Panhandle region in the lower Shenandoah Valley. The mission of the National Maritime Center (NMC) is to issue credentials to fully qualified mariners in the most effective and efficient manner possible in order to assure a safe, secure, economically viable and environmentally sound Marine Transportation System. The National Maritime Center is granted authority through federal mandates listed in the Code of Federal Regulation (CFR), NVIC, and Coast Guard Policy Letters. NMC is a headquarters unit under the United States Coast Guard who works under the auspices of the Department of Homeland Security.


In 1982, the United States Coast Guard established Regional Exam Centers (REC) throughout the United States to process mariner licenses and documents. There are currently 17 RECs strategically located throughout the United States. In 1997, the United States Coast Guard created the National Maritime Center in Arlington, VA, to manage the Coast Guard’s Merchant Mariner licensing program. In 2008, the National Maritime Center moved to its new home in Martinsburg, WV. The United States Coast Guard centralized its Mariner License Document (MLD) program and changed its name to the Merchant Mariner Credentialing (MMC) program. The 17 RECs operate as “storefronts and advocates” for mariners.


The NMC has a fully staffed Customer Service Center dedicated to helping mariners navigate through the Merchant Mariner credentialing process. On average, they reply to over 1400 contacts, over 360 e-mails, over 160 chats /tickets via LiveHelp, and resolve 95% of all issues within the CSC, allowing maximum resources put towards producing credentials. They also mail out an average of 45 Merchant Mariner Credentialing Application Packages daily. They can be contacted via email at IASKNMC@USCG.MIL and their phone number is 1-888-427-5662.
