Maritime industry stakeholders who wish to be added to the automatic email distribution list for U.S. Maritime Alerts and Advisories should self-register at https://public.govdelivery.com/accounts/USDOTMARAD/signup/34916, even if they were previously registered, prior to November 31^st, 2023.  This GovDelivery-based self-registration site will help all U.S. government agencies participating in this system better determine which maritime industry stakeholders are and are not currently receiving U.S. Maritime Alerts and Advisories.

Any subscription changes, questions, problems, or recommendations should be forwarded, along with a current phone contact number, to MARADSecurity@dot.gov.

Please note that the U.S. Maritime Alerts and Advisories System is meant primarily to highlight certain threats to U.S. commercial vessels and mariners operating on international voyages and is not meant to cover all regional threats as the resources listed below, among others, already cover a wide variety of these threats:
