You can find your Frontier 13-digit ticket number in your confirmation email, e-ticket receipt, or the My Trip section of the Frontier website or app. It’s different from your confirmation code, which is the 6-character reference you use to access your reservation. Keep both handy for check-in, booking changes, cancellations, and customer service requests. If you can’t locate your ticket number, the steps below will help you track it down fast.
Quick Answer
Your Frontier ticket number is the 13-digit code on your confirmation email or e-ticket receipt, usually labeled “Ticket Number.” You can also find it by logging into My Trip with your last name and 6-character confirmation code.

What Is Your Frontier Ticket Number?
Your Frontier ticket number is a unique 13-digit code that identifies your specific flight reservation. You’ll use it to verify booking details, manage check-in, track baggage, and request changes. Frontier links the number to your last name and 6-character confirmation code for security, so only you can pull up the record on the website or app.
You’ll usually find the ticket number in your confirmation email or inside the My Trip section. If it isn’t obvious, check your spam or junk folder for Frontier’s message. If digital access fails, you can reach customer service by phone, chat, or text for help.
Note: If a travel agency or third-party site (like Expedia or Google Flights) booked your flight, you may have two confirmation codes — one from the agency and one from Frontier. Always use the 6-character Frontier code when checking in or managing your trip on flyfrontier.com, since that’s the one tied directly to your ticket number.
Ticket Number vs Confirmation Code
Your Frontier ticket number is a unique 13-digit identifier that tracks your reservation, while your confirmation code is a shorter, 6-character alphanumeric code you use to pull up booking details. You’ll need the ticket number mainly for ticket management and proof of purchase, while the confirmation code handles check-in and reservation changes. Keep both secure, since each plays a different role.
Ticket Number Basics
A Frontier ticket number is a 13-digit identifier tied directly to your flight purchase — think of it as proof that your fare exists and has been issued. It appears on your e-ticket receipt or itinerary near your flight details, and airlines use this same 13-digit format industry-wide for electronic tickets. You’ll need it if you contact customer service or want to verify payment, so store it with your other travel records. Check your email confirmation or printed itinerary to find it quickly.
Confirmation Code Differences
While the ticket number confirms your Frontier fare has been issued, the confirmation code serves a different purpose: it’s the 6-character code (for example, FLY123) you use to open your booking online. You’ll usually find both in your e-ticket receipt, in the confirmation email, and — for the confirmation code specifically — on your boarding pass. The ticket number links to Frontier’s system for accounting, check-in, changes, and cancellations, while the confirmation code is mainly for retrieving trip details fast. Keep both handy so you can move through check-in and changes without friction.
Known Traveler Number vs Ticket Number
Don’t confuse your ticket number with your Known Traveler Number (KTN), also called your PASS ID if you’re enrolled in TSA PreCheck, Global Entry, or another Trusted Traveler Program. Your KTN is printed on the back of your membership card, or you can find it by logging into your Trusted Traveler Program account. You add your KTN to your Frontier profile separately from your ticket number — it doesn’t replace it.
Check Your Email and E-Ticket Receipt
Check your email inbox first, since Frontier sends an e-ticket receipt after booking. Look for subject lines like “Itinerary” or “Booking Confirmation” to find the message with your 13-digit ticket number. If it isn’t there, check your spam or junk folder, then open the receipt and locate “Ticket Number” near the top.
Check Email Inbox
Your Frontier ticket number usually appears in the confirmation email you received after booking, often labeled “Ticket Number.” If you can’t find that message, check your spam and junk folders, since confirmation emails sometimes get filtered there by mistake.
- Search your inbox for “Frontier” and “Ticket Number”
- Have your last name and confirmation code ready
- Review your inbox, spam, and junk folders
- Request a resend through Frontier if the email never arrived
This approach helps you locate the number without waiting on support. Once you find the confirmation email, you can verify your booking details right away.
Find E-Ticket Receipt
You’ll usually see your ticket number on your e-ticket receipt, which Frontier sends to your registered email after purchase. Open that message and note the number — this is what links your fare to your booking. If the email isn’t visible, check spam or junk folders, since filters can hide it. You can also use the My Trip section on Frontier’s website or app: enter your last name and confirmation code to retrieve the receipt there. If you need a paper copy, print the receipt directly. If you still can’t locate it, contact Frontier customer support for help.
Retrieve Booking Details in My Trip
To retrieve your Frontier booking details, go to the My Trip section on the website or app and sign in with your last name and confirmation code. After signing in, you can review your itinerary, confirm flight data, and check for reservation updates without delay.
- Locate your 13-digit ticket number in the booking details
- If you can’t find your confirmation code, check email, spam, or junk
- Use the resend itinerary option if needed
- Keep ID and travel documents ready before making changes
My Trip also lets you adjust existing plans and add FRONTIER Miles when eligible. Entering your details accurately here saves you time and keeps you from needing to call an agent for routine requests.
Find Your Ticket Number in the App
Open the Frontier app and go to My Trip to see your booked flights. Your 13-digit ticket number usually appears next to the confirmation code and itinerary. Open the specific reservation, then tap the flight to view more detailed booking data.
If the ticket number doesn’t show right away, make sure you’re signed into the Frontier account linked to your booking — the app only displays records tied to the correct profile. The ticket number typically sits with your itinerary summary and fare info on the flight details screen. You can also cross-check it against your email confirmation, which includes the same booking receipt.
Pro Tip: Save a screenshot of your ticket number and confirmation code to your phone before you travel. That way you have both on hand even without cell service or app access at the airport.
What to Do If You Can’t Find Your Ticket Number?
If you still can’t find your Frontier 13-digit ticket number, start by checking your confirmation email — it’s usually listed in the subject line or body — and look in spam or junk folders too. If that doesn’t work, try these steps:
- Log in to Frontier’s My Trip page with your confirmation code and last name
- Check your email filters so important messages aren’t getting buried
- Contact Frontier customer service by phone, chat, or text for your booking details
- If a travel agency booked your flight, ask them directly for your Frontier ticket number
Work through each option in order, and you’ll typically recover your ticket number without much delay.
Check In With Your Ticket Number
Once you’ve found your Frontier ticket number, you can use it — along with your confirmation code — to check in online and skip the airport counter. Enter the code exactly as shown on your confirmation email or in the Frontier app, then verify your reservation and save your boarding pass. In the app, your boarding pass is stored digitally, so you can pull it up on your phone at security and the gate without printing anything.
Open the My Trip section to view your booking details and locate the ticket number near the fare information. Keep it ready before you begin check-in. If the confirmation email isn’t visible, check your spam folder first.
Use Your Ticket Number to Change or Cancel
When you need to change or cancel your Frontier reservation, you’ll typically use your confirmation code and last name to access the booking on the website or app — Frontier’s system then references your ticket number behind the scenes to process the update.
Need to change or cancel your Frontier reservation? Keep your ticket number, confirmation code, and last name ready for quick access.
- Find your codes in your confirmation email or travel itinerary
- Enter your confirmation code with your last name to open the booking
- Review fare rules before changing, since fees may apply depending on your fare type
- If you cancel, your ticket number is used to track any refund or flight credit
Warning: Frontier tickets are generally non-refundable to your original payment method, except when you cancel within 24 hours of booking on a flight departing 7 or more days out. Outside that window, cancellations are typically issued as flight credit rather than a cash refund — check your fare rules before you cancel.

Frequently Asked Questions
Where do I find my Frontier ticket number?
You’ll find it on your confirmation email, itinerary, or in My Trip after logging in with your last name and confirmation code. If you booked through a travel agency, your receipt or boarding pass should also show it — or you can ask the agency directly.
How do I find my 13-digit ticket number?
Check your booking email, e-ticket receipt, or Frontier account/app for a field labeled “Ticket Number” or “Document Number.” If it’s missing, contact Frontier customer support and they can look it up using your name and travel dates.
What is the 13-digit airline ticket number?
It’s the unique ID assigned to your booking when your e-ticket is issued — the format generally starts with a 3-digit airline code followed by 10 more digits. You’ll need it to manage your trip, request refunds or credits, and resolve disputes with customer service.
What is the 3-1-1 rule on Frontier?
Frontier follows the same TSA rule as every U.S. airline: each liquid container must be 3.4 ounces (100 ml) or less, and all your containers must fit in a single quart-sized bag. This rule remains unchanged as of 2026, with exceptions for medically necessary liquids and baby formula that you declare separately at the checkpoint.

Now you know how to find your Frontier 13-digit ticket number, tell it apart from your confirmation code, and use it to manage check-in, changes, or cancellations. If your email or app doesn’t show it, Frontier’s My Trip tool and 24/7 customer service can get you back on track. Keep your ticket number and confirmation code together with your travel records — a little preparation now saves a lot of hassle when plans shift.
