Frequently Asked Questions
Does a National Car Rental coupon code apply to the full price of the rental?
Most codes apply only to the retail base rate for time and mileage, not to taxes, fees, optional protection products, or fuel charges. That's worth factoring in when comparing a discounted quote against a competitor's all in price.
What is the Emerald Club and is it free to join?
Emerald Club is National's loyalty program, and standard enrollment is free for anyone 21 or older. Members earn one rental credit per qualifying rental, with five credits typically converting into a free rental day that can be redeemed with no blackout dates.
Will I be charged a fee if I cancel my reservation?
It depends on how the reservation was booked. Standard reservations paid at the counter usually cancel free of charge, while prepaid "pay now" bookings can carry a cancellation fee if canceled close to the pickup time, and a larger no show fee if the car isn't picked up at all.
How does the fuel policy work, and can I avoid extra charges?
National offers a few fuel options at pickup: return the car with a full tank to avoid fuel charges, prepay for a full tank upfront and return it empty, or skip refueling and pay National's per gallon rate at return, which runs higher than local pump prices. Returning the car full is generally the cheapest option.
Are there seasonal promotions that stack with an Emerald Club membership?
National periodically runs limited time promotions, like earning a bonus free rental day after a set number of qualifying rentals within a promotional window, on top of the standard credits members already earn. These typically require registering separately even for existing members.
Do Emerald Club credits or free days expire?
Free rental days earned through the standard program can be redeemed with no blackout dates, though promotional bonus days from limited time offers usually carry their own redemption window and expire if not used by a set date.
Is there a discount for renting through a partner airline or hotel program?
Yes, National partners with a range of hotel and airline loyalty programs, letting members earn points or miles on a qualifying rental in addition to Emerald Club credits, though this typically has to be linked at the time of booking rather than added afterward.
