The port from which cargo depart. This may be a seaport or aerial port from which merchandises flow to a port of debarkation; it may or may not coincide with the port of origin. Also called port of exit.

On a travel or immigration form, the "Port of Embarkation" is the location where you physically boarded the vehicle (airplane, ship, or bus) that brought you to your current destination. If you flew directly from London to New York, your port of embarkation is London. However, if you had a connecting flight—for example, flying from Mumbai to London and then to New York—your port of embarkation for the US immigration form is typically the city where you boarded your last flight into the country (London). For a cruise, the port of embarkation is the city where the ship first started the voyage and where you checked in with your luggage. It is essential to write the name of the city and the country clearly. Incorrectly filling this out can cause confusion during the customs process, as authorities use this data to track the path of travelers and monitor for potential health or security risks based on the regions you have recently transited through.
