Registration with the Embassy and Safety Message for American Citizens
The cornerstone of our efforts to keep the American traveling public aware of problems threatening their safety and security is our Consular Information Program. If you would like to receive important information issued by the U.S. Department of State and the Embassy in Cambodia, please register your stay in Cambodia using this online registration service https://travelregistration.state.gov/ibrs/. By indicating your e-mail address at the time of registration, you will receive all Embassy bulletins and warden messages automatically.
As the Department continues to develop information on any potential security threats to U.S. citizens overseas, it shares credible threat information through its consular information program documents, available on the Internet at http://travel.state.gov. In addition to information on the Internet, travelers may obtain up-to-date information on security conditions by calling 1-888-407-4747 toll-free in the U.S. or outside the U.S. and Canada on a regular toll line at 1-317-472-2328. Travel Warnings, Travel Alerts and other general information are also available on the U.S. Embassy Cambodian website.
