National Car Rental's main phone number and what it handles

National Car Rental's primary customer service number is 1-844-382-6875. This line handles reservations, changes to existing bookings, roadside information claims, and general questions about your rental. The number works from the United States and is available during business hours; wait times vary depending on call volume and the time of day you call.

When you call, have your reservation confirmation number ready if you're calling about an existing rental. If you're making a new reservation, the agent will ask for your travel dates, pickup location, and driver's license information. National also operates a separate line for roadside information if your car breaks down or you're locked out during your rental period.

Key Takeaways

  • National's main customer service number is 1-844-382-6875 and handles reservations, booking changes, and general questions.
  • Roadside information during a rental is reached through a separate number printed on your rental agreement and key tag.
  • You can also manage many reservation changes online through your National account without calling.
  • International renters and those calling from outside the US should check their rental agreement for location-specific contact numbers.
  • Peak call times (early morning, late afternoon, weekends before holidays) typically have longer wait times than mid-day weekday calls.

Roadside information and emergency support numbers

If your rental car breaks down, you get a flat tire, or you lock yourself out, do not call the main reservation line. Instead, look for the roadside information number on your rental agreement and on the key tag attached to your keys. This number connects you directly to a dispatch center that can send a tow truck or locksmith to your location without the wait you'd face on the main line.

Roadside information is included in most National rentals at no extra charge. When you call, have your rental agreement number and your exact location ready. The dispatcher will ask what happened and whether you need a tow to a repair facility or just a lockout service. Response times depend on your location—urban areas usually see help within 30 to 60 minutes, while rural areas may take longer.

Making changes to an existing reservation online

You do not always need to call to modify a reservation. National's website lets you log into your account using your confirmation number and email address, then change your pickup or return date, upgrade your car class, add a driver, or remove extras like GPS or insurance. Changes made online are when ready and you receive a confirmation email right away.

Online changes work best when you're adjusting dates or adding services. If you need to move your pickup to a different location, cancel and rebook, or discuss damage coverage options, calling is usually faster because an agent can walk through your options and make sure you understand the cost difference.

International and location-specific contact numbers

If you're renting a National car outside the United States, the 1-844 number will not work. Instead, check your rental agreement or the National website for the phone number for your country or region. National operates in Canada, Mexico, the Caribbean, Europe, and other locations, each with its own customer service line.

When you book an international rental, National sends you a confirmation email that includes the local contact number for your destination. Save this number before you travel. If you lose it, you can also call the main US line and ask for the international support team, though you may be charged international calling rates depending on your phone plan.

What to have ready before you call

Calling National goes faster when you gather information first. If you're calling about an existing rental, have your confirmation number (a six-character code sent in your booking email), your driver's license number, and the rental location and date ready. If you're making a new reservation, have your travel dates, preferred pickup location, and driver's license handy.

If you're calling about damage to the car, have photos or a description of what happened and the location where it occurred. If you're disputing a charge on your bill, have your rental agreement and credit card statement in front of you. Agents can usually resolve issues faster when you provide details upfront rather than having them search for your account while you wait.

When to call versus when to use other contact methods

Phone is the fastest option if you need an when ready answer or if your situation is complex—for example, if you need to add an extra driver last-minute, if you're disputing a charge, or if you have questions about insurance coverage. Calling also works well if you're not comfortable using the website or if you want to hear options explained before deciding.

Email is slower but useful if you're not in a hurry and want a written record of your request. National's website contact form lets you submit questions and you'll receive a response within one to two business days. Live chat is sometimes available on the National website during business hours and can be faster than phone if you dislike waiting on hold, though availability varies by time of day.

Frequently Asked Questions

What time does National customer service open and close?

National's main customer service line operates during standard business hours, typically 7 a.m. to 11 p.m. Eastern Time, seven days a week. Hours may vary by season and holiday. Roadside information is available 24/7 for renters with an active rental agreement, so if your car breaks down at night, use the roadside number on your rental agreement, not the main line.

Can I make a reservation by phone, or do I have to use the website?

You can make a reservation by calling 1-844-382-6875. An agent will walk you through available cars, rates, and add-ons. Phone reservations take longer than booking online (usually 10 to 15 minutes versus 2 to 3 minutes), but some people prefer it because they can ask questions and hear options explained before committing.

What if I'm calling from outside the US?

The 1-844 number is US-based and may not work from outside the country. Check your rental agreement or National's website for the customer service number in your location. If you're renting in the US but calling from abroad, you can use the main number, but you'll pay international calling rates unless you use a VoIP service like Skype.

How long does it usually take to reach an agent?

Wait times range from a few minutes to 20 or more minutes depending on call volume. Early morning (before 9 a.m.), mid-day (11 a.m. to 2 p.m.), and weekday afternoons typically have shorter waits. Avoid calling on Friday afternoons, Saturday mornings, and the day before major holidays, when wait times are longest.

What if I need to cancel my reservation?

You can cancel online through your National account or by calling 1-844-382-6875. Cancellation policies depend on your rate type—some rates are fully refundable if you cancel before your pickup date, while others charge a fee. Check your confirmation email for your specific cancellation terms before you call, so you know what to expect.
