National Trust Car Rental's main phone number is 1-800-328-4567

That number connects you to their central reservations line, which handles new bookings, changes to existing reservations, and general questions about their rental locations and rates. The line is staffed during business hours, typically 7 a.m. to 11 p.m. Eastern time, seven days a week. Wait times vary by season — peak travel periods like summer and holidays can mean 10 to 20 minutes on hold.

If you need to reach a specific rental location directly rather than the central line, you can find individual branch numbers on the National Trust website by searching for the city or airport where you plan to pick up your car. Local branches can sometimes answer questions faster about their own inventory and local policies, though they cannot always modify reservations made through the central system.

Key Takeaways

  • The main National Trust reservations number is 1-800-328-4567, open 7 a.m. to 11 p.m. Eastern time daily.
  • Call this number to make a new reservation, change an existing one, or ask about rates and vehicle availability.
  • Individual rental locations have their own direct phone numbers, which you can find on the National Trust website by location.
  • Peak travel seasons mean longer hold times, so calling during off-peak hours (early morning or weekday afternoons) may get you through faster.

What you can do on the phone versus online

The reservations line handles everything you can do on the website — booking a car, selecting your dates and location, choosing insurance options — but a phone agent can also answer questions about specific vehicle types, explain policy details that might be unclear, and sometimes offer verbal quotes or promotions not visible on the website.

If you already have a reservation and need to make changes, you can do this online through your account or by phone. Phone agents can sometimes waive or reduce change fees in situations where the website system cannot, though this depends on the specific circumstances and the agent's authority. For cancellations within 24 hours of your pickup time, calling is often faster than waiting for an online cancellation to process.

When to call versus when to use other contact methods

Call the main number if you need an when ready answer, want to discuss options with a person, or have a complex situation — for example, if you need to add an additional driver, arrange for a child car seat, or discuss accessibility needs. The phone line is the fastest way to handle these requests because an agent can ask follow-up questions and confirm details in real time.

Use the website or mobile app if you are making a straightforward reservation, checking your existing booking, or looking up rental location hours and addresses. Email is slower but works if you have a detailed question or complaint that does not need an when ready response. Some National Trust locations also offer live chat on their website during business hours, which can be faster than phone hold times during peak periods.

What to have ready before you call

If you are calling to modify an existing reservation, have your confirmation number handy — it is in your confirmation email and in your National Trust account. If you are booking a new rental, have your driver's license information, the dates you need the car, and your pickup and return locations ready. This speeds up the call and reduces the chance of errors in your reservation.

If you are calling about a problem with a past rental — damage, billing, or a lost item — have your rental agreement number and the dates of your rental. The agent will need this to pull up your account and investigate. If you are disputing a charge, have your credit card statement or bank record showing the transaction.

International and after-hours options

The 1-800 number works only from within the United States. If you are calling from outside the U.S., look for the international phone number on the National Trust website for your region, or use the online contact form to send a message. Response times for email inquiries are typically 24 to 48 hours.

National Trust does not have a dedicated after-hours emergency line for roadside information or rental problems that occur outside business hours. If you have a breakdown or accident during your rental, check your rental agreement for the roadside information number — this is usually a separate line that operates 24/7. If you need to cancel or modify a reservation after 11 p.m. Eastern time, you can do this through your online account, and the change will process the next business day.

Common reasons people call and what to expect

The most common call is to make a new reservation or modify an existing one. These calls usually take 5 to 15 minutes depending on how many changes you need and how busy the line is. The second most common reason is to ask about vehicle availability or upgrade options — agents can check real-time inventory and sometimes offer upgrades at the current rate or a small upcharge.

Calls about damage disputes, billing errors, or lost items take longer because the agent needs to review your rental history, contact the location, and sometimes escalate to a manager. These calls can take 20 to 30 minutes. If your issue is complex, ask the agent if you can be transferred to a supervisor or if someone will call you back — this can be faster than staying on hold.

Frequently Asked Questions

Can I make a reservation over the phone without a credit card?

No. National Trust requires a valid credit card to hold any reservation, whether you book by phone or online. The card is charged at pickup, not when you make the reservation. You can use a debit card in some cases, but the agent will explain any restrictions or holds that may explore.

What if I call and the wait time is too long?

Hang up and try again during a quieter time — early morning (7 to 9 a.m. Eastern) or weekday afternoons (2 to 4 p.m.) usually have shorter waits than evenings or weekends. You can also book or modify your reservation online, which is when ready, or send an email if your question is not urgent.

Do I need to call to add a driver to my reservation?

You can add an additional driver online through your account, or call to do it by phone. Either way, the additional driver must be present at pickup with a valid driver's license. Some locations charge a fee for additional drivers; the agent can tell you the amount when you call.

What happens if I call to cancel within 24 hours of pickup?

Most National Trust reservations can be cancelled free of charge up to 24 hours before pickup. If you cancel within 24 hours, you may be charged a cancellation fee — the amount depends on your rate type and how far in advance you booked. The agent can tell you the exact fee before you confirm the cancellation.

Can I call to dispute a charge after my rental?

Yes. Call the main reservations line and explain the charge you are disputing. The agent will review your rental agreement and the charges applied. If the dispute involves damage or an accident, the process may take longer because the location needs to provide documentation. You can also dispute the charge with your credit card company if you cannot reach an agreement with National Trust.
