What Is a Hertz Confirmation Number and How Does It Work?
When you book a rental car through Hertz — whether online, through the app, by phone, or via a third-party travel site — you receive a confirmation number at the end of the process. This number is your proof that the reservation exists and is the key reference point for everything that follows: check-in, modifications, cancellations, and billing disputes.
Understanding what this number does, where to find it, and when you'll need it can prevent delays and confusion at the counter — especially when you're tired, running late, or at an unfamiliar airport location.
What the Confirmation Number Actually Is
A Hertz confirmation number is a unique alphanumeric code assigned to a specific reservation. It ties together the details of your booking: the pickup location, date and time, return location, vehicle class selected, rate applied, and any extras you added (like insurance coverage, a GPS unit, or a car seat).
It is not a receipt, a payment record, or a guarantee of a specific vehicle. It confirms that a reservation has been created in Hertz's system under those terms.
The format is typically a string of letters and numbers — often around 10 to 12 characters — though this can vary depending on how the reservation was made and whether it came through a third-party booking platform.
Where to Find Your Confirmation Number
Hertz sends a confirmation email immediately after a completed booking. That email contains the confirmation number, usually displayed prominently near the top. It also summarizes your reservation details.
Other places the number may appear:
- The Hertz app — under "My Trips" or your reservation history
- Your Hertz Gold Plus Rewards account — if you're a member and were logged in when booking
- A third-party booking platform — sites like Expedia, Priceline, or travel agencies generate their own confirmation number and may include the Hertz confirmation number separately; these are not always the same
- Printed or digital itineraries — if booked through a corporate travel manager or airline bundle
🔍 If you booked through a third party and only received their confirmation number, that may not be enough to pull up your reservation directly in Hertz's system. It's worth confirming which number Hertz actually has on file before your pickup date.
When You'll Need It
The confirmation number matters most at these points:
At pickup: The counter agent or kiosk will ask for it to locate your reservation. Having it ready speeds up the process. If you're a Gold Plus Rewards member using an express lane or skipping the counter, the number is still used to link your reservation to the correct vehicle.
When modifying a reservation: Changes to pickup time, vehicle class, or return date require the reservation to be pulled up by confirmation number. This applies whether you're calling Hertz directly or making changes online.
If there's a billing issue: Charges that appear on your card after the rental — for fuel, damage, tolls, or fees — should always be tied to your reservation. Your confirmation number helps Hertz's customer service team locate the rental and the associated charges quickly.
For cancellations: If you cancel, Hertz will typically reference the confirmation number in the cancellation email as well. Keep both until you've confirmed no further charges appear.
Confirmation Numbers vs. Rental Agreement Numbers
These are different. 📋
| Confirmation Number | Rental Agreement Number | |
|---|---|---|
| When issued | At booking | At vehicle pickup |
| Purpose | Confirms the reservation | Documents the active rental |
| Used for | Modifying, canceling, or checking in | Post-rental disputes, receipts, damage claims |
Once you pick up the car, the rental agreement number becomes the more relevant reference. Both numbers may be needed if you're resolving a dispute after the rental closes.
What Affects Whether Your Confirmation Number Works Smoothly
Several variables shape the experience around a confirmation number:
How the booking was made: Direct bookings (Hertz.com or the app) usually integrate cleanly with Hertz's counter systems. Third-party bookings introduce an additional layer — the third party holds the reservation, and Hertz receives the details through a data feed. Delays or mismatches in that feed can occasionally cause issues.
Membership status: Gold Plus Rewards members have reservations tied to their profile. If the confirmation number and member number don't match, it can create confusion at the counter.
Corporate or negotiated rate bookings: These reservations are often tied to a corporate account code. The confirmation number alone may not reflect the correct rate without the account code also being present.
International pickups: If you're renting outside the U.S. through Hertz (or a Hertz affiliate brand), the confirmation number format and the system it lives in may differ. What works on Hertz.com may not directly translate to a local affiliate's terminal.
If You Can't Find Your Confirmation Number
Check your spam or junk folder first — confirmation emails occasionally get filtered. Search your inbox for "Hertz" or the email address [email protected].
If you still can't locate it, Hertz can look up a reservation using your name, email address, pickup location, and date. Having that information ready before you call or visit will help. If the booking went through a third party, that platform's customer service team may also be able to retrieve it on their end.
Your specific experience — what information Hertz needs, how the number was formatted, and whether a third-party booking transferred correctly — depends on where and how you made the reservation and which systems were involved.
