Sixt's main customer service number and what it covers
Sixt's primary phone number in the United States is 1-888-749-8227. This line handles reservations, changes to existing bookings, and general customer service questions. The number works during business hours, which vary by location but typically run 7 a.m. to 11 p.m. Eastern time, seven days a week.
When you call, have your reservation number ready if you're modifying an existing booking. If you're making a new reservation, the agent will need your driver's license information, the pickup location, and your travel dates. Sixt also operates regional numbers for specific locations — some airport branches and city centers have direct lines — but the main 1-888 number can route you to any branch.
Key Takeaways
- Sixt's main U.S. customer service number is 1-888-749-8227, available seven days a week during extended hours.
- Have your reservation number, driver's license, and travel dates ready before calling to speed up the process.
- Airport and major city locations often have direct phone numbers listed on Sixt's website, which may have shorter wait times than the main line.
- For roadside emergencies or issues during your rental, look for the emergency contact number on your rental agreement or the Sixt app.
- International travelers should check Sixt's website for the phone number for their specific country, as numbers differ by region.
Finding the phone number for a specific Sixt location
If you need to reach a particular Sixt branch — such as an airport location or downtown office — the fastest way is to visit Sixt's website, enter your city or airport code, and view the branch details. Most locations display a direct phone number alongside their address and hours. Calling a specific branch can be faster than the main line if you're picking up or dropping off at that location.
Airport branches often have their own dedicated numbers because they handle higher call volume. If you're renting at Los Angeles International, for example, searching "Sixt LAX" on the Sixt website will show you the branch phone number, which may connect you more quickly than the national line.
What to do if you're already renting a car
If you're currently in the middle of a rental and need help, your rental agreement includes an emergency contact number specific to your situation. Check the paperwork you received at pickup or open the Sixt mobile app, which displays roadside information and customer service numbers for active rentals.
For mechanical problems, accidents, or lockouts during your rental, use the emergency number on your agreement rather than the main customer service line. These emergency lines are staffed 24/7 and route you to someone who can dispatch help to your location or arrange a replacement vehicle.
Phone alternatives if you prefer not to call
Sixt offers other ways to reach customer service without calling. The Sixt mobile app lets you message customer service directly, and most inquiries receive a response within a few hours during business days. The website also has a contact form where you can describe your issue and request a callback.
For straightforward changes — like extending your rental dates or adding a driver — the Sixt app and website often let you make the change yourself without contacting anyone. This is usually faster than calling, especially during peak hours.
International Sixt rentals and phone numbers
If you're renting a Sixt car outside the United States, the phone number changes by country. Sixt operates in Europe, Asia, Australia, and other regions, each with its own customer service line. Before your trip, visit Sixt's website for your destination country and note the local customer service number.
Many international Sixt locations offer phone support in English, but response times and hours vary. Some countries' Sixt branches prioritize online booking and app-based support over phone lines, so check what's available in your destination before you arrive.
Common reasons to call Sixt and what information to have ready
The most common reasons people call Sixt are to make a reservation, modify pickup or dropoff dates, add an extra driver, or report a problem with a vehicle. For any of these calls, have your driver's license number, the dates you need the car, and your preferred pickup location ready before you dial.
If you're calling about an existing reservation, your confirmation number will speed things up. If you're reporting a vehicle issue during a rental, have your rental agreement number and a description of the problem. For damage claims or accidents, have photos and the other party's insurance information if applicable.
Wait times and best times to call
Sixt's main line typically has shorter wait times early in the morning (before 9 a.m.) and late evening (after 7 p.m.). Midday and early afternoon, especially on weekdays, tend to have longer queues. If you're flexible on timing, calling outside peak hours can reduce your hold time.
Calling a specific branch location instead of the national line often results in shorter waits, particularly if you're calling about a pickup or dropoff at that branch. Weekend call volume is usually lighter than weekday volume, though some branches have reduced staffing on Sundays.
Frequently Asked Questions
What's the best way to reach Sixt if I'm outside the U.S.?
Visit Sixt's website for your country and look for the local customer service number. Each country has its own phone line. If you're traveling internationally and need help during your rental, your rental agreement includes an emergency contact number that works from anywhere.
Can I make a reservation over the phone, or should I book online?
You can reserve by phone at 1-888-749-8227, but online booking through the Sixt website or app is usually faster and lets you see all available vehicle options and prices at once. Phone reservations work well if you have questions about vehicle types or need help choosing.
What if I get a busy signal or the wait is too long?
Try the Sixt app or website to handle your request yourself — many changes and new bookings can be completed without calling. You can also use the website contact form to request a callback, which typically comes within a few hours on business days.
Is there a different number for roadside emergencies?
Yes. Your rental agreement includes a 24/7 emergency number for accidents, breakdowns, or lockouts. Check your paperwork or the Sixt app for this number — it's different from the main customer service line and connects you to emergency support when ready.
Do I need to call to add an extra driver to my reservation?
You can often add a driver through the Sixt app or website before your pickup date. Calling is an option if you prefer, but online changes are usually faster. Additional drivers may have an extra fee depending on your rental agreement.
