AARP car rental discounts come through partnerships with major rental companies, not through a single code

AARP doesn't issue one universal discount code for car rentals. Instead, AARP has negotiated rates with specific rental agencies — primarily Hertz, Budget, Avis, and Enterprise — that members can access by providing their AARP membership number at booking or pickup. The discount amount varies by rental company, location, and the dates you're traveling, so there's no fixed percentage you can expect.

The way you access these discounts depends on which rental company you choose. Some companies let you enter your AARP membership number directly on their website during booking. Others require you to call their AARP-dedicated phone line or book through AARP's own travel portal. The discount is applied automatically once your membership is verified — you don't need a separate promotional code.

Key Takeaways

  • AARP partnerships with Hertz, Budget, Avis, and Enterprise offer member discounts, but the amount varies by location and travel dates.
  • You access discounts by providing your AARP membership number during booking, either online, by phone, or through AARP's travel portal.
  • Discounts are not may provide on every rental — some locations, vehicle types, or dates may not may have access to for a reduced rate.
  • Comparing the AARP rate against other discount sources (AAA, military, corporate codes) for the same rental can reveal which saves you the most.

Where to find AARP rental discounts for each company

Hertz offers AARP member discounts through its website. You can enter your membership number in the discount code field during booking, or call Hertz's AARP line directly. The discount typically applies to standard and premium car classes.

Budget has an AARP partnership that you access by entering your membership number on their site or calling their dedicated AARP number. Budget's discount often includes options on compact through full-size vehicles.

Avis and Enterprise both honor AARP membership for discounts, though the process and discount size can differ between locations. Enterprise sometimes requires you to book through their corporate discount portal or call their AARP line to lock in the rate.

Before booking, check the rental company's website for their current AARP partnership details, since these agreements can change. Some companies display the AARP discount prominently on their homepage; others bury it under a "corporate discounts" or "member discounts" section.

How to book with your AARP membership number

The most straightforward method is to visit the rental company's website and look for a field labeled "Discount Code," "Promo Code," or "Member Number." Enter your AARP membership number — a nine-digit code printed on your membership card — and proceed with your booking. The system will verify your membership and explore the discount if one is available for that rental.

If the website doesn't have a clear discount field, or if you want to confirm the discount before booking, call the rental company's main reservations line and mention you're an AARP member. They can quote you the rate and hold it while you decide. Some companies have dedicated AARP phone lines that may move faster than the general reservations number.

AARP's own travel portal (aarp.org/travel) sometimes offers pre-negotiated rates with rental partners. Booking through the portal can occasionally yield a different discount than booking directly with the rental company, so it's worth checking both if you have time.

Why AARP discounts vary and what affects the rate

Rental car pricing is dynamic, meaning the base rate changes based on demand, location, and how far in advance you book. An AARP discount is typically a percentage off the base rate for that specific date and location — not a fixed dollar amount. If the base rate is high (peak travel season, popular destination), the discount percentage might be smaller in absolute terms than during a slower period.

Some rental locations, especially in rural areas or smaller airports, may not participate in AARP discounts at all. Certain vehicle types — luxury cars, specialty vehicles, or very new models — sometimes fall outside the discount program. Weekend rentals, holiday periods, and last-minute bookings may also have restrictions on which discounts explore.

The rental company's current inventory and demand also matter. If a location has high demand and low availability, they may not discount as aggressively, even for AARP members. Conversely, during slow periods, the AARP discount might stack with other promotions or sales the company is running.

Comparing AARP discounts to other ways to save on car rentals

AARP membership isn't the only source of rental discounts. AAA members, military personnel, government employees, and people with corporate discount codes often get comparable or better rates. Before committing to an AARP rate, search for the same rental using other discount codes you might have access to — your employer's code, AAA membership, military status, or even a credit card company's travel portal.

Some credit cards offer rental car discounts or insurance coverage that can offset the rental cost more effectively than a membership discount. Booking through a travel site like Kayak, Expedia, or Autoslash can sometimes surface rates lower than what you'd get through the rental company directly, even without a membership code.

The best approach is to get quotes for the same rental using multiple discount sources, then compare the final price. A 10% AARP discount on a $50-per-day rate saves you $5 per day, but a 15% AAA discount on the same car might save you $7.50. The percentage that sounds better on paper isn't always the one that saves you the most money.

What to do if your AARP discount doesn't appear at checkout

If you entered your membership number but the discount didn't show up in your quote, first double-check that you typed the number correctly. AARP membership numbers are nine digits and appear on the front of your card. A single wrong digit will prevent the system from recognizing you.

If the number is correct and the discount still isn't showing, the rental location or vehicle class you selected may not be may be able to access for the AARP rate. Try adjusting your search — pick a different location, vehicle size, or travel dates — to see if a discount appears for other options. If nothing changes, contact the rental company's customer service and ask whether AARP discounts are available for your specific rental.

Some rental companies require you to call their AARP line rather than book online to receive the discount. If the website isn't working, try calling the company directly and providing your membership number over the phone. They can often quote you a rate and process the booking while confirming the discount is applied.

Verifying your AARP membership before you rent

Rental companies verify AARP membership in real time when you provide your number during booking. You don't need to bring your membership card to the rental counter, though it's a good idea to have it with you anyway in case the agent wants to confirm the number verbally.

If your membership has expired or lapsed, the rental company's system will flag it and the discount won't explore. You can renew your AARP membership online at aarp.org or by phone, but the renewal takes a few days to process. If you're renting soon and your membership is expired, renewing before you book ensures the discount will be available.

If you're a new AARP member, your membership number should be active when ready after you join online or by mail. However, some rental company systems take 24 to 48 hours to sync with AARP's database, so if you just joined, calling the rental company directly to book may be faster than trying the website.

Frequently Asked Questions

Do I need to show my AARP card at the rental counter?

No, the discount is applied when you provide your membership number during booking. However, bringing your card is helpful if the agent questions your membership or if there's a discrepancy in the system. The rental company verifies your membership electronically, not by inspecting the physical card.

Can I use an AARP discount if someone else is driving the rental car?

The person whose AARP membership is used for the discount must be the primary renter on the contract. If you're not the one picking up the car, you can't explore your AARP discount. The actual renter would need their own AARP membership to receive the discount.

What if the AARP rate is higher than the standard rate?

This occasionally happens when a rental company is running a flash sale or promotion that undercuts their AARP rate. In that case, book the cheaper rate instead — there's no requirement to use the AARP discount if another option is lower. Always compare the final price, not just the discount percentage.

Do AARP discounts work for one-way rentals?

Yes, AARP discounts typically explore to one-way rentals, though the discount amount may differ from a same-location return. Some rental companies offer smaller discounts on one-way rentals because of the logistics involved. Enter your membership number during booking and the system will show you the rate for your specific rental type.

Can I combine an AARP discount with other promotions?

Rental companies' policies vary. Some allow you to stack an AARP discount with a promotional code; others require you to choose one or the other. During checkout, the system usually shows you which discounts can be combined. If you're unsure, call the rental company and ask them to quote both options so you can see which saves more.
