MU San Juan exam services will be by appointment only. Appointments for counter services are highly recommended as we cannot guarantee that walk-ins will be accommodated. Late arrivals for examination appointments may not be permitted and could require rescheduling to another appointment date; if allowed to test after arriving late, an applicant will only receive the amount of time remaining within the exam session.
In all cases, applicants and visitors who are experiencing or demonstrating symptoms indicating an illness will not be permitted to enter the REC/MU and will need to reschedule their appointment.
For an examination appointment: applicants shall bring a photo ID. Applicants are encouraged to bring their own #2 pencils, a non-programmable calculator and plotting equipment, if applicable, as we cannot guarantee that these items will be available at the REC. No other personal belongings are allowed in the examination room. Examinations will not be administered unless an applicant has paid all applicable user fees and has an approved-to-test (ATT) letter.
Applicants may submit an application via email which is the preferred method to MMCApplications@uscg.mil, or by fax or mail.
Applicants are encouraged to pay their user fees prior to arrival at the REC using Pay.gov.
Medical applications and supporting medical documentation should be sent via e-mail to MEDAIP@uscg.mil . Please include your full name in the subject line and ensure attachments are in PDF format.
Awaiting Information (AI) Documentation – To ensure fastest processing please send AI documentation to MMC-Awaiting-Info@uscg.mil.
Current letters from the NMC requesting Merchant Mariner Credential (MMC) AI documentation instruct mariners to send the information to IASKNMC@uscg.mil.

General Building Access Requirements: The REAL ID Act of 2005 prohibits Federal agencies from accepting, for official purposes, driver's licenses and identification cards from states not meeting the Act's minimum standards. On May 7, 2025, Federal agencies will be prohibited from accepting driver's licenses and identification cards from the listed states for accessing federal facilities and military installations. In order to gain access to an REC, you will be required to provide a valid driver's license or identification card from a state that meets the Act's minimum standards OR by providing some form of currently valid federal identification (passport, TWIC, MMC, etc.). Failure to provide proof of acceptable identification will prevent you from entering the REC to conduct business which may affect your credential and/or application.
