What you need to know about National Car Rental codes
National Car Rental stands out for its Emerald Aisle — a self-service lot where Executive and Executive Elite members skip the counter entirely and choose any car on the lot. The unique "Emerald Aisle" feature is the most loved perk in the rental industry. National's contract IDs are tied to corporate accounts but a few public codes (AAA, AARP) are widely available. Status match into Executive is among the most common rewards strategies for frequent business travelers.

How to use National Car Rental corporate codes
- Go to National Car Rental's website or app.
- Select "Add a discount code" or "Corporate/Business rate" at booking.
- Enter the code from the table above.
- Verify your affiliation if prompted (e.g., AAA membership number).
- Save the code to your loyalty profile so it auto-applies on future rentals.
How National Car Rental codes compare to member rates
Signing up for Emerald Club is free and lets you store a Contract code in your profile so it auto-applies on future bookings. Member rates can sometimes match or beat the Contract ID / Corporate Rate rate during promotional periods (especially weekend specials and pay-now rates), so the best strategy is to compare both with and without your discount code at booking. The mobile app's price comparison is the fastest way to see which yields the lower total.
Pro tips for 2026
- National's Emerald Aisle is the single best perk in the rental industry for frequent travelers. Executive and Executive Elite members walk to the Aisle and pick any car on the lot — no paperwork, no upsell pressure. This alone justifies consolidating business rentals with National.
- Many Fortune 500 employers have a National corporate contract that auto-grants Executive status to their traveling employees. Check with your HR or travel department before booking at the public rate — your employer may already have a contract giving you a better deal.
- Status match into National Executive is the easiest of the three big brands. Submit proof of Hertz President's Circle or Avis President's Club via National's online form, and Executive status is granted within 1-2 weeks. Matched status is valid through the end of the following calendar year.
- For international rentals (Europe, Latin America), National is owned by Enterprise Holdings. The Emerald Aisle and Executive benefits are similar at international locations, but the corporate contract rates may differ — verify with the local office before booking.

Frequently asked questions
What is the best National Car Rental discount code?
For public codes, AAA (5028252) and AARP (5225314) yield up to 20% off most locations. Costco Travel (X120300) is competitive for longer rentals. Many Fortune 500 employees get corporate contract rates automatically through their employer's travel program — check with your HR or travel department before booking at the public rate.
How do I get National Emerald Executive status?
Three main paths: (1) Earn 12 paid rentals or 40 paid rental days in a calendar year. (2) Status match from Hertz President's Circle or Avis President's Club — submit proof via National's status match form. (3) Many corporate accounts grant Executive status automatically; check if your employer has a National contract. Executive is the magic tier for the Emerald Aisle.
What is the Emerald Aisle and why is it special?
The Emerald Aisle is National's signature self-service lot at most airport locations. Executive and Executive Elite members bypass the rental counter, walk to the Aisle, and choose any car in their booked class or above. No paperwork, no upsell pressure, no waiting. It's the closest thing to the "grab any car" experience in the rental industry and the reason many frequent travelers prefer National.
Is National cheaper than Hertz or Avis?
At base rates, National is usually 5-15% cheaper than Hertz and on par with Avis. With a corporate contract or Emerald Club status, the value proposition shifts — Emerald Aisle access is unique to National and worth the slight premium for status holders. For one-off leisure rentals, Budget or Enterprise is usually cheaper.
Can I use a National contract code as a leisure renter?
National contract codes are technically tied to the contracting organization. Some are public (AAA, AARP, Costco). Others are corporate-specific and reserved for employees of the named company. Using a corporate-specific code without affiliation can result in rate adjustments at pickup — book a public code (AAA/AARP) if you don't have legitimate access to a corporate rate.
What is National's Executive Elite tier?
Executive Elite is the top Emerald Club tier, requiring 25 paid rentals or 85 paid rental days in a calendar year. Benefits include guaranteed upgrades to premium cars (when reserving midsize or above), priority customer service, and best-in-class service recovery. Executive Elite also gets you access to National's "Executive Elite" line, often shorter than the standard Emerald Aisle at busy airports.
