The invention discloses a method and system for acquiring logistics information of transnational transport. The method and the system offer a user a one-stop whole-course logistics inquiry service, enable the whole-course logistics information of the transnational transport to be inquired at one inquiry interface and the user may acquire whole-course transnational transport information among an initial transport agent, a transfer country transport agent, and a terminal transport agent with one-time inquiry. Using the method, the user is no longer required to inquire at the websites of transport agents in various countries for transnational transport so that logistics inquiry time is greatly shortened and logistics inquiry efficiency is increased. The method and the system have important significance to the associated practitioners in this industry.
