Rentalcars.com Promo Codes & Coupons September 2025

If your Rentalcars.com promo code isn’t working, it’s usually because the code is expired, not valid for your booking location or dates, or entered incorrectly. Error messages like “This code is not valid for your booking” or “Promo code expired” often appear when there’s a problem.

Rentalcars.com promo codes often have specific terms, such as booking windows, pick-up locations, or car categories. For example, some codes are only valid for bookings made before a certain date, or for rentals in specific countries or cities. Codes may also exclude certain dates (like peak travel periods) or require a minimum spend. Double-check the code for typos—codes are often case-sensitive and must be entered exactly as shown. Promo codes may not work with special deals or discounted rates.

To troubleshoot:

1. Verify the code’s validity period and location restrictions.
2. Ensure your booking meets all requirements (dates, car type, location).
3. Enter the code exactly as provided, without extra spaces.
4. Try a different code if the current one is not accepted.

Pro tip: Always read the promo code’s terms and conditions before booking, and try applying the code early in the checkout process to catch any issues right away.

Yes, Rentalcars.com promo codes are typically case-sensitive, meaning you must enter them exactly as shown, including any uppercase or lowercase letters.

If you enter a code with the wrong capitalization, you may see an error message like “Invalid promo code” or the code simply won’t apply. This is a common issue, especially when copying codes from emails or websites. Always double-check the code’s format and avoid adding extra spaces before or after the code.

Pro tip: Copy and paste the promo code directly from the source to avoid mistakes with capitalization or spacing.

No, Rentalcars.com only allows one promo code per booking.

The checkout system will only accept a single code, and if you try to enter a second code, it will either replace the first or display an error. This is a standard policy for most online travel sites, including Rentalcars.com, to prevent stacking multiple discounts on a single reservation. If you have multiple codes, choose the one that offers the best value for your specific booking.

Pro tip: Compare all available codes before booking, and use the one with the highest discount or most relevant perks for your trip.

Yes, there are restrictions—promo codes on Rentalcars.com often apply only to specific locations, dates, car types, or rental partners. For example, some codes are valid only for bookings in certain countries (like Mexico or Australia), during specific timeframes, or for select car categories. Codes may also exclude peak travel dates or require bookings to be made before a certain deadline.

To check if your booking qualifies:

• Review the promo code’s terms and conditions, which outline all restrictions.
• During checkout, enter the code; if your booking doesn’t qualify, you’ll see an error message explaining why.
• Look for any fine print about excluded dates, locations, or car types.

Pro tip: Always check the promo code’s terms before planning your trip, and if your booking doesn’t qualify, try adjusting your pick-up location or dates to fit the code’s requirements.
