Sixt customer service channels and response times
Sixt operates a customer service line you can reach by phone, email, and live chat. The fastest route depends on what you need: phone calls for urgent issues like a breakdown or late return, email for billing questions or reservation changes, and chat for quick clarifications during business hours. Sixt also maintains a help center on their website where you can search answers to common questions without waiting for a representative.
Response times vary by channel and time of day. Phone lines typically connect you within a few minutes during peak hours (8 a.m. to 6 p.m. weekdays), though wait times can stretch longer on Fridays and around holiday periods. Email responses usually arrive within 24 hours on business days. Live chat is available during limited hours and may have a queue during busy times.

Phone support for when ready issues
Call Sixt at 1-800-749-8227 (1-800-SIXT-CAR) for problems that need same-day attention: a vehicle breakdown, a late return, damage to the car, or a missing key. This number connects you to Sixt's main customer service team. Have your reservation confirmation number ready, along with your driver's license number and the phone number associated with your booking.
If you are calling from outside the United States, Sixt maintains country-specific numbers listed on their website. International callers should visit Sixt.com and select their country to find the local support line. Some locations also offer 24-hour roadside information through a separate number provided in your rental agreement.
Phone lines are staffed Monday through Friday, 8 a.m. to 6 p.m. Eastern Time. Weekend and after-hours calls may be routed to an automated system or voicemail. If you have a breakdown or emergency during off-hours, check your rental paperwork for the roadside information number, which is staffed around the clock.
Email and online contact forms
Sixt accepts email inquiries through their website contact form, which is faster than sending an email directly because it routes your message to the right department. Visit Sixt.com, scroll to the footer, and click "Contact Us" to find the form. Fill in your reservation number, the nature of your issue, and your preferred contact method. Sixt typically responds within one business day.
Email works best for non-urgent matters: billing disputes, questions about your rental agreement, requests to modify a reservation, or feedback about your experience. Include your reservation number and a brief description of what you need. If you are writing about a charge on your credit card, include the transaction date and amount.
The online form also allows you to upload photos or documents. This is useful if you are reporting damage to the vehicle, disputing a charge, or providing proof of an accident. Attach clear images and keep file sizes under 5 MB per upload.
Live chat and mobile app support
Sixt offers live chat on their website during business hours. Look for the chat icon in the lower right corner of Sixt.com. Chat works well for quick questions about rates, vehicle availability, or how to complete a reservation. Representatives can also help you locate a nearby Sixt location or explain rental policies. Chat is not ideal for account-specific issues because representatives may not have access to your reservation details without you providing them manually.
If you are already renting from Sixt, the mobile app includes a messaging feature that connects you directly to support. Open the app, go to your active reservation, and select "Contact Support" or "Message Us." This channel is useful for questions about your current rental, such as where to return the vehicle or how to report a problem with the car.
Finding a Sixt location near you
Sixt operates rental counters at major airports and in city centers across the United States. To find the location nearest you, visit Sixt.com and use the "Find a Location" tool. Enter your city or zip code, and the site will show all nearby branches with their hours and phone numbers. Airport locations typically have longer hours than city branches.
If you prefer to speak with someone in person, you can visit a Sixt counter to ask questions about your reservation, pick up a rental, or handle a return. Staff at the counter can also help with billing questions or damage disputes, though complex issues may still be referred to the main customer service line.
What information to have ready before you contact Sixt
Gather these details before calling or emailing so the representative can find your reservation quickly: your confirmation or reservation number, the dates of your rental, your driver's license number, and the phone number you used to book. If you are calling about a charge or billing issue, have the credit card you used and the transaction date.
For damage or accident reports, have the location where the incident occurred, the date and time, and the names and phone numbers of any other parties involved. If you have photos of the damage, have those ready to upload or describe. For roadside emergencies, know your current location and the vehicle's license plate number.
Frequently Asked Questions
Can I change or cancel my reservation by phone?
Yes. Call 1-800-749-8227 with your reservation number and the dates you want to change. Cancellation fees depend on your rate type and how close you are to your rental date, so ask the representative to explain any charges before confirming the change.
What should I do if I have a breakdown during my rental?
Check your rental agreement for the roadside information number, which is staffed 24 hours. Call that number first, not the main customer service line. Provide your location, vehicle description, and the nature of the problem. Sixt will arrange a tow or send a replacement vehicle depending on the issue.
How do I dispute a charge on my credit card from Sixt?
Contact Sixt's billing department through the website contact form or by calling 1-800-749-8227. Include the transaction date, amount, and your reservation number. Sixt will review the charge and respond within a few business days. If you cannot reach resolution, you can also dispute the charge with your credit card company.
Is there a way to contact Sixt outside of business hours?
For emergencies during your rental (breakdown, accident, late return), use the roadside information number on your rental agreement, which operates 24/7. For non-emergency questions, leave a voicemail or use the website contact form, and Sixt will respond the next business day.
Can I get a refund if I return my rental early?
Refund may be able to access depends on your rate type. Call 1-800-749-8227 or use the contact form to ask about your specific reservation. Some rates are non-refundable, while others allow a partial refund if you return the vehicle early enough. The representative can calculate what you would receive.
