How to use Sixt corporate codes
- Go to Sixt's website or app.
- Select "Add a discount code" or "Corporate/Business rate" at booking.
- Enter the code from the table above.
- Verify your affiliation if prompted (e.g., AAA membership number).
- Save the code to your loyalty profile so it auto-applies on future rentals.
How Sixt codes compare to member rates
Signing up for Sixt Express / Sixt Card is free and lets you store a Corporate code in your profile so it auto-applies on future bookings. Member rates can sometimes match or beat the Corporate Customer Number (CDP) rate during promotional periods (especially weekend specials and pay-now rates), so the best strategy is to compare both with and without your discount code at booking. The mobile app's price comparison is the fastest way to see which yields the lower total.
Pro tips for 2026
- Sixt's fleet in Europe is significantly better than Hertz or Avis — typical vehicles are Mercedes, BMW, Audi, and VW. For European road trips, Sixt is the top choice for vehicle quality even at a 10-15% premium.
- The Sixt Card Platinum ($99/year) is the only paid rental loyalty program with real value. Guaranteed upgrades, no advance booking required, and priority service make every rental a "premium experience" for the cost of a few rental days.
- Sixt runs aggressive first-rental coupons (10-25% off) via email signup. Sign up on sixt.com before your first booking to receive the welcome offer — combined with Amex Platinum's AMEXPLAT code, you can stack for the deepest discount.
- For US rentals, Sixt is still building its airport presence. Major international airports (LAX, JFK, ORD) have full-service Sixt locations; smaller airports may not. Verify the location exists before booking at a smaller airport.

Frequently asked questions
What is the best Sixt discount code in 2026?
For US/Canada, the Amex Platinum code (AMEXPLAT) is the most consistent, yielding 10% off and stronger at premium vehicles. For Europe, AAA's European code (CDP-AAA-EUR) varies by country but is widely accepted. Sixt also runs frequent promo codes via email — signing up for their newsletter typically yields a 10-15% first-rental coupon.
Is the Sixt Card Platinum worth $99 per year?
For 3+ Sixt rentals per year, yes. The card includes guaranteed car class upgrades, no advance booking requirement (you can rent walk-in at participating locations), and priority service. For European business travelers who use Sixt frequently, the convenience benefits easily justify the cost. For occasional renters, the free Sixt Express tier is sufficient.
Does Sixt have a status match program?
Sixt does not officially advertise a status match program, but customer service has historically been generous with status extensions to frequent customers or holders of high-tier status with competing programs. The most reliable way to upgrade Sixt status is the Sixt Card Platinum subscription or accumulating 3+ rentals in a 12-month period for Gold, 10+ for Platinum.
Is Sixt cheaper than Hertz or Avis?
At base rates, Sixt is often comparable to Hertz and Avis for standard vehicles and cheaper for premium cars in Europe. The premium car selection is Sixt's strength — Mercedes, BMW, and Audi are typical fleet vehicles, where Hertz or Avis often offer only Ford or Chevy. The Sixt Card Platinum effectively makes every rental a "premium upgrade" experience for a fixed annual cost.
Does Sixt have the best loyalty program of any rental company?
Arguably yes, for European business travelers. The Sixt Card Platinum is the only paid rental loyalty program, but the benefits (guaranteed upgrades, no advance booking, priority service) are unique. The Diamond tier (invitation-only) is comparable to Hertz President's Circle but harder to reach. In the US, Sixt is still building its airport presence, so the loyalty program is less mature than Hertz or Avis.
Can I use Sixt codes in the US?
Yes — Sixt operates at most major US airports with the same booking system as Europe. Most corporate and promotional codes (including Amex Platinum's AMEXPLAT) work in both US and European Sixt locations. The fleet in the US skews more toward standard sedans and SUVs, with premium vehicles available at a premium surcharge.
