Carla Car Rental Promo Codes & Under-25 Waiver

1. Waive the under-25 fee on marked cars

   No young-driver fee at the counterLow effortDrivers under 25

   Carla's help centre says the young-driver fee isn't part of the total price and is usually $30 to $40 a day, charged by the rental branch. Cars showing an "Underage fee waived" banner come without it once you search with your correct age, though not every car qualifies. Carla's own figures for the saving differ: $40 a day in its help centre and $25 a day in its February 2026 guide for US renters, which also says young renters booking through Carla may only rent Economy through Luxury cars.^{[2, 4, 6]}

   1. Give your correct age in the search form before you search.
   2. Choose a car carrying the "Underage fee waived" banner, on the website or in the app.
   3. Book as usual; Carla says no young-renter fee is then charged at the counter.

2. Take a promo rate when your dates are fixed

   Lower rates, but no refundLow effortTrips that won't change

   Carla's terms describe two kinds of booking: Flexible, which refunds 100% of the prepayment when you cancel at least 48 hours before pickup, and promo rates on the Standard policy, which the terms say often come with lower rates but are non-refundable, even if you cancel or never collect the car. Within the Flexible policy, optional Trip Cancellation Coverage refunds everything except its own fee when you cancel up to 6 hours before pickup.^[3]

3. Apply a promo code before you search

   One code per bookingLow effortNewsletter readers and social followers

   Carla's Promo Codes page says codes go out through its newsletter, social media and limited-time partner campaigns. You enter one on rentcarla.com/promo, select Apply and then search, and the discount appears on the checkout page; only one code works per reservation, and none can be added once payment is complete. If a code fails, Carla points to expiry dates and typos first, then to its support team.^[1]

   1. Watch Carla's newsletter, social media and partner campaigns for a current code.
   2. Enter it in the Promo Code field on the Promo Codes page and select Apply.
   3. Search for cars and check the discount on the checkout page before paying.

4. Book in the Carla app for app-only discounts

   Discounts only app users seeLow effortAnyone with a smartphone

   Carla's home page and its US city pages advertise discounts that are exclusive to app users, without naming amounts. The app is also where Carla Cash is applied at checkout, and Carla's help centre says Carla Plus can currently be joined only in the app. Its app page adds that cancelling a free-cancellation deal in the app costs nothing.^{[2, 5, 7, 8]}

5. Pick an off-airport pickup and like-for-like fuel

   Cheaper pickups and fuel termsSome effortTravelers who can take a shuttle

   Carla's own advice on choosing a car says an off-airport pickup with a shuttle bus can be much cheaper than an airport counter, and that a like-for-like fuel policy can save a lot when you won't drive far. Its terms add that some rental companies run a free shuttle from the airport to their office, so compare both kinds of location in your results.^{[2, 3]}

6. Join Carla Plus if you rent often

   $19 Carla Cash a month; cancel free 3 hours outSome effortFrequent renters

   Carla Plus is a monthly membership with priority support, free cancellation with 100% back up to 3 hours before pickup and $19 of Carla Cash every month; the help centre says the monthly Carla Cash equals the subscription fee and the first amount arrives after your first pickup as a member. There's no trial period, Carla's terms make membership charges non-refundable, and cancelling takes effect at the end of the current billing month. Carla Cash pays only the pay-now part of a booking.^{[2, 3]}

Carla shares its promo codes through its newsletter, social media and limited-time partner campaigns, and one code goes into the Promo Code box on its Promo Codes page before you search. We list only codes and standing offers Carla shows on rentcarla.com; its Promo Codes page showed no code on November 9, 2026.

1. Mixing Carla Cash and a card changes the refund

   Carla's terms say that when a booking is paid partly with Carla Cash and partly by card, a cancellation refunds only the Carla Cash part, and the card payment is non-refundable. Refunded Carla Cash is available at once for future bookings, but it can't be turned into cash or transferred to another user.^[3]

2. Cancel through Carla, not the rental desk

   Carla's terms ask renters to make cancellations and changes through Carla and warn that cancelling with the rental company may make you ineligible for a refund. A booking can't be cancelled once the car has been picked up.^[3]

3. Protection Plan claims have a 10-day window

   Carla's help centre says its Protection Plan costs less than cover sold at the counter, and it can still be added from the Reservations tab before pickup. The terms make it secondary to any existing insurance or CDW and require a claim within 10 days with photos, invoices, the rental agreement, a police report and card statements; scratches, damage while the car is parked or you're not in it, off-road and rural roads and animal strikes are excluded, and a change of car class or dates has to be reported at pickup.^{[2, 3]}

4. Carla Plus charges aren't refunded

   Carla's terms make Carla Plus membership charges non-refundable, and its help centre says there's no trial period. Cancelling stops future charges from the end of the current billing month; the terms describe cancelling in the app, while the help centre says to contact support.^{[2, 3]}

5. Choose the market that matches your licence

   Carla's terms say prices, promotions and included services can vary with the booking channel, your location and the market selected, and ask renters to pick the market of the country that issued their driving licence. Carla charges in the currency shown at checkout, in rare cases in US dollars at the bank's exchange rate, and conversion fees from your bank or card are yours to pay.^[3]
