Hertz is back with a new rental car promotion, offering customers a free day when they rent for 4 or more days and pick up the vehicle no later than September 30, 2026.

Let’s take a look at the details of this new offer.

Rent for 4+ Days, Get 1 Free Day With Hertz

Hertz is out with a new offer for members to get a free day when renting for 4 or more days in the U.S. This offer applies to pickups through September 30, 2026, but you don’t have to return the car by the date — just pick it up to begin your rental.

This new promotion applies to the base rental rate but not any taxes or add-ons, and it doesn’t apply to rentals of more than 27 days.

To score this discount, use the promo code 212109 at the time of reservation.

Is This Discount Worth It?

This promotion is undoubtedly a good way to save on a Hertz rental car, but you might be eligible for a better discount.

For example, if you hold the Platinum Card^® from American Express, you can use code CDP #211762 to get a discounted rate year-round, plus a complimentary 4-hour grace period on returns. Other credit cards may offer similar perks at Hertz and other rental car companies.

Hot Tip:

Consider paying for your rental car with a credit card that includes a rental car damage waiver. This way, you don’t have to pay a daily fee and aren’t liable for damage incurred to the vehicle.

Your employer, alumni association, or professional group may also have Hertz corporate discount codes available. These can provide significant savings and other perks, like an included damage waiver or extra drivers.

Because of this, you should always compare the price you see from these promotions to other prices for which you’re eligible. Additionally, compare the price of booking a rental car with Hertz to other rental car companies like Avis and National. There are a handful of websites that can automate this process for you.

Final Thoughts

Hertz is offering a free day when you rent for 4 or more days in the U.S. and pick up your vehicle no later than September 30. Multiple vehicle types are eligible for this offer, but it’s not available in other countries.

This discount is a great way to save on upcoming rentals. However, you should always compare the price you see to discounts you may have through a credit card, your company, or other organizations you belong to.
