Merchant Mariner Credential Application Information and Help
The cost of applying for a USCG issued Merchant Mariner Credential (MMC) is about $500 to $600. This includes the USCG application and issuance fees, the TWIC enrollment fee, the average cost of the physical exam and drug screening, and the cost of the required First Aid/CPR Training. This does not include the cost of any training courses, travel, and lodging.
While it is not a requirement, it is highly recommended that you submit your application to the USCG and get your approval PRIOR to taking the course.
The steps provided here outline the Merchant Mariner Credential application process and start with the least expensive step first.
Application Step 1 – Document your Sea Service
Research the endorsement you need and the professional requirements for that endorsement. All OUPV and Master applications require at least 360-days of qualifying sea service experience, that includes 90-days of recent experience within the past 3-years. Use form CG 719S to document your experience.
Application Step 2 – Enroll in the TWIC Program
All original applications for an OUPV or Master require the applicant to enroll in the TWIC program through a Universal Enrollment System (UES).
Application Step 3 – Physical Exam and Drug Screening
All OUPV and Master applications must include a Merchant Mariner Physical Exam completed on form CG 719K, and a USCG/DOT Drug Screening completed on form CG 719P. When applying for an OS only use form 719KE instead of 719K.
Application Step 4 – First Aid/CPR Training
The original issuance of an OUPV or Master requires completion of American Red Cross or American Heart Association First Aid/CPR Training within one year of the application date.
Application Step 5 – Application Form
All applications require completion of form CG 719B. Complete form CG 719C if answering yes to any Convictions and Drug Use questions in Section III.
Application Step 6 – Oath and Application Fees
All applications must be delivered to a USCG Regional Exam Center (REC) either in person; or by fax, mail or email. When delivering the application in person the Merchant Mariner Oath and application fees can be taken care over the counter at the REC. Otherwise the oath may be administered by a Notary.
