If I have questions, either technical or subject matter related, is there a contact person or help desk to assist me?

Yes, once you have informed us of your intention to participate in AES, you will be assigned a CBP Client Representative and a Census Client Representative to help you get established in AES. In addition, there is a toll-free AES Hotline at 1-800-549-0595 to take your questions.
