CG Form 719B – USCG Merchant Mariner Credential Application

CG-719B Form PDF Details

The CG-719B is the official U.S. Coast Guard application for a Merchant Mariner Credential (MMC). The USCG requires this form for all mariners seeking certification. It is issued by the National Maritime Center (NMC) under the Department of Homeland Security.

This form covers six application types. Original MMC applications are for mariners applying for the first time. Renewal applications are for mariners with credentials expiring within one year. Duplicate requests replace lost, stolen, or damaged credentials. Raise of grade (ROG) applications are for mariners seeking higher officer certifications. New endorsements add authorization for additional vessel types or waters. Medical Certificate requests allow mariners to add or update their health certification.

The form also covers Document of Continuity (DOC) requests. A DOC provides proof of sea service between MMC renewals. It does not carry endorsements. Entry-level ratings are issued automatically with certain training certifications. No separate application is required for those ratings.

All mariners receive a single MMC that consolidates all their endorsements. The credential lists officer endorsements, rating endorsements, and special purpose endorsements. Endorsements specify vessel type, tonnage, waters navigated, and propulsion mode. Mariners may hold both Domestic and STCW endorsements on one credential.

The CG-719B must be submitted with supporting documentation. This includes proof of sea service, proof of citizenship, a medical certificate, and TWIC card information. Applications without all required documents are returned without processing.

For questions about the form, contact the USCG National Maritime Center directly. Applicants may also visit a Regional Exam Center (REC) for in-person assistance with the application process.
