What do I do if I need help completing my EVUS enrollment?

A friend, relative, travel industry professional, or another third party may submit the required information to EVUS on your behalf. Additional information is also available on CBP’s informational EVUS website atwww.cbp.gov/evus. If an applicant has questions about how to fill out the application or issues with the EVUS site, they can contact the EVUS Call Center at 00-1-202-325-0180. The Call Center is available 24 hours per day, 7 days per week, but is closed on U.S. federal holidays. The Call Center is staffed with Mandarin speakers. You may also contact the Call Center by email atevus@cbp.dhs.gov. The Call Center is available to answer questions travelers might have regarding EVUS, but all EVUS enrollments must be submitted online by the traveler or a third party. U.S. Embassies and Consulates are not able to provide details about EVUS enrollments or resolve the issue that caused an unsuccessful enrollment.
