You’re standing at the airport curb. Your luggage is heavy, the humidity is hitting 90%, and the shuttle bus you were expecting just drove off without you. All you want is to get into your midsize sedan and drive. But something is wrong with your reservation, or maybe you left your sunglasses in the center console of the car you just returned. You need the National Car Rental number, and you need it to actually work.
Most people just Google it and click the first thing they see.
Big mistake.
The primary National Car Rental number for general reservations in the United States is 1-844-382-6875. If you are calling for customer service specifically—meaning you’ve already rented or have a beef with a bill—you’re better off hitting 1-844-393-9989.
Here is the thing about car rental giants. They’ve spent millions of dollars on IVR systems designed to keep you from talking to a person. It’s not that they hate you; it's just that humans are expensive to employ. But when your credit card has a $500 "mystery charge" on it, a robot won't solve that.
Why the National Car Rental Number is Your Best Friend (and Worst Enemy)
National is a premium brand. It’s owned by Enterprise Mobility, which also owns Alamo and, obviously, Enterprise. Because National caters heavily to the business traveler—the "Emerald Club" road warrior who doesn't have time to wait in line—their phone support is generally a notch above the budget brands.
But "generally better" is a relative term.
If you call the main line during a massive winter storm in Chicago or a system-wide outage, you’re going to be listening to that generic jazz loop for forty minutes. Honestly, it's frustrating. You’ve probably noticed that the number on your rental agreement sometimes leads to a local branch that never picks up. That’s because the guys at the airport are busy washing cars and checking in returns. They aren't sitting by a desk phone.
When you dial 1-844-382-6875, you’re entering the corporate ecosystem.

The Emerald Club Shortcut
If you’re an Emerald Club member, stop calling the general lines. You have a dedicated lane. Members should use the specific loyalty line found on the back of their digital or physical membership card. For those who can't find it, 1-800-962-7070 is the magic portal for Emerald Club Member Services.
It’s faster.
Usually, the wait times are sliced in half because National prioritizes their frequent fliers. It’s a tiered system of respect. If you rent forty times a year, they want to keep you happy. If you’re a once-a-year vacationer, you’re just a number in the queue.
What About Roadside Assistance?
This is a different beast entirely. Do not call the reservation number if your tire is flat or the engine is smoking. You’ll just waste time being transferred. The National Roadside Assistance number is 1-800-367-6767.
They are available 24/7.
When you call this line, have your rental agreement number ready. It’s that long string of digits at the top of your paperwork or in your email confirmation. Without it, the agent will struggle to locate your exact vehicle in their fleet. If you’re in a dangerous spot—like the shoulder of a high-speed interstate—tell them immediately. They have protocols for high-risk recoveries.
The Secret to Skipping the Bot
We’ve all tried it. We scream "Agent!" or "Representative!" into the phone like a crazy person. Sometimes it works. Sometimes the bot just says, "I'm sorry, I didn't get that."
To get through the National Car Rental number menu effectively, try pressing "0" repeatedly or saying "Feedback" or "Complaint." For some reason, the software is often programmed to prioritize people who sound like they are about to leave a one-star review. It sounds cynical, but it’s a reality of modern customer service architecture.

Another trick? Call at weird times.
Everyone calls at 9:00 AM or 5:00 PM. If you call at 10:30 PM EST, you’re much more likely to get a human within three minutes. National operates call centers in various locations, so they are staffed around the clock, but the volume drops significantly after the West Coast business day ends.
Handling Billing Disputes Without Losing Your Mind
Let’s talk about the "Fuel Charge" or the "Cleaning Fee." These are the two biggest reasons people call the National Car Rental number after their trip. You returned the car with a full tank, but they charged you $9.00 a gallon anyway.
Don't call the local branch for this.
The person at the counter usually doesn't have the "admin" rights to reverse a finalized corporate invoice. You need the Revenue Management or Billing department. Call the customer service line (1-844-393-9989) and ask specifically for "Billing Support."
Have your receipt from the gas station ready. If you don't have a physical receipt, a screenshot of your credit card statement showing a charge at a gas station within 5 miles of the airport will usually suffice. National is actually pretty reasonable about this if you have proof. They know their automated fuel sensors can be finicky.
International Rentals
If you are calling from outside the U.S. or Canada, the 844 numbers might not work. Every country has its own local contact point. For example, if you’re in the UK, you’re looking at 0800 051 6666. If you’re traveling abroad, always download the National app before you leave. The app has a "Call Us" button that automatically routes you based on your GPS location and the country associated with your booking. It saves a ton of international roaming charges.
Common Misconceptions About National’s Phone Support
A lot of people think that the person on the other end of the National Car Rental number can give them a free upgrade.

They can't.
Phone agents deal with the "what" and the "when," but the "which" (as in which car you get) is handled entirely by the lot attendants and the branch manager. If you want a Cadillac instead of a Chevy, the phone agent can change your reservation class, but they can't "hook you up" with a specific car sitting in the Executive Selection row. That’s a face-to-face negotiation.
Also, calling to "check if a car is available" is often a waste of time during peak seasons. The inventory moves so fast that by the time you hang up the phone, the last minivan has already been swiped by someone at the counter. Trust the website's real-time inventory; it’s directly linked to the same database the phone agents use.
What to Do If You Can't Get Through
Sometimes the phone lines are just dead. It happens. If you’ve been on hold for an hour, pivot.
National is surprisingly responsive on social media. Twitter (X) is usually the best bet. Tag @NationalPro with your issue (but don't post your reservation number publicly). Their social media team often has a direct line to corporate escalations that the general phone bank doesn't.
Alternatively, use the website's "Contact Us" form. While it feels like sending a message into a black hole, National’s system generates a "Case Number." This case number is gold. If you have to call back later, saying "I have an existing case number, it's 12345," gets you past the basic troubleshooting questions and straight to someone who can actually help.
Actionable Steps for Your Next Rental
To make your life easier, follow this workflow:
- Save the Numbers Now: Put "National Customer Service" (1-844-393-9989) and "National Roadside" (1-800-367-6767) in your contacts. You don't want to be searching for them on a dark highway.
- Join Emerald Club: It’s free. Even if you only rent once a year, you get access to the better phone lines and the ability to bypass the counter.
- Document Everything: Take a photo of your fuel gauge and the car's exterior when you drop it off. If you have to call the National Car Rental number to dispute a charge, these photos are your "Get Out of Jail Free" card.
- Use the "Extension" Strategy: If you need to extend your rental while you have the car, don't just keep it and hope for the best. Call the number. If you don't, they might flag the car as overdue, which can lead to "theft" protocols or, at the very least, a much higher "rack rate" for the extra days.
- Check the Invoice Immediately: National usually emails your receipt within minutes of the car being scanned back in. Look at it before you leave the airport property. It is 100% easier to fix a mistake at the exit booth than it is over the phone three days later.
National is built for efficiency, but even the best systems have friction. Knowing which specific National Car Rental number to dial—and when to dial it—is the difference between a minor speed bump and a ruined vacation. Keep your reservation number handy, stay calm with the agents, and always ask for a "reference number" for the call if they promise you a refund. If it isn't documented, it didn't happen.
