National Car Rental is bringing back a fan-favorite: the One Two Free promotion for Emerald Club members. This limited-time offer lets members earn a free rental day after every two qualifying rentals — and longer trips can help you get there even faster.
Here’s how it works and what you need to do to maximize the deal.

National Car Rental Emerald Club ‘One Two Free' Promotion
Emerald Club members earn one free day for every two eligible rentals of two or more consecutive days. Plus, longer rentals count as more than one rental, which means you can rack up free days without having to book several trips.
To qualify, you’ll need to register for the promotion before your rentals are completed. Then, rent a midsize or larger vehicle from National between April 1 and June 22, 2025.
Make sure your account is set to earn Emerald Club credits — not airline miles or other partner rewards — to receive credit toward free rental days.
The promotion is valid at participating U.S. and Canada locations, and you can register retroactively after a rental — as long as it’s completed by June 22, 2025.

Earning additional free days with longer rentals
Each qualifying rental of two to seven days counts as one credit toward a free rental day. But if you rent for more than a week, National will give you extra credit based on the total number of days. The table below spells out how it works:
Even though one longer rental can count for multiple credits, you still need to complete at least two rentals total to unlock your free days. So, if you rent a car for 15 days, you’ll earn three credits — but you’ll need a second rental (of any eligible length) to put those credits to use.

Our Take
If you plan to rent a car from National this spring, the One Two Free promo is well worth signing up for. With a simple registration and just two qualifying rentals, you’ll unlock a free day — no coupons or complex hoops to jump through.
Better yet, if one of your trips is longer than a week, you could be just a single short rental away from scoring a free day. Just make sure you’ve opted into earning Emerald Club credits and booked a midsize or larger vehicle — then enjoy the ride (and the rewards).
