Before you contact Sixt
SIXT provides vehicle rentals and mobility services. Its US rental terms identify a national reservations and customer-service line, with a separate number for roadside assistance.
- Keep the pickup location, rental dates and reservation or agreement number available.
- For an invoice or change to an active rental, use SIXT’s official service tools and the applicable rental terms.
SIXT labels this its national reservation and customer-service line in its current US terms PDF. Roadside assistance is a separate service.
Numbers have not been test-called. Availability and any calling charges depend on the company, your location and your phone provider.
