E-Ticket Numbers By Airline: Everything You Need to Know

Last Updated on July 28, 2026 by Daniel Globe

An e-ticket number is the standard 13-digit document number assigned to an issued airline ticket. It helps the airline identify the ticket you paid for, but it is not the same as your booking reference, flight number, or boarding pass. Knowing which code is which makes check-in, changes, refunds, receipts, and mileage claims much easier.

What Is an E-Ticket Number?

An e-ticket number is the document number for an airline ticket that has been issued electronically. Industry ticketing documentation describes the standard number as 13 digits: a 3-digit airline ticketing code, a 4-digit form number, and a 6-digit serial number. The ticket is stored in the airline or reservation system, so you do not need a paper ticket to prove that it exists.

The number identifies the ticketed document, not merely the reservation. That distinction matters because a booking can exist before payment and ticket issuance are complete. If you have a confirmation code but no ticket number, the reservation may still be on hold, may be awaiting ticketing, or the carrier may use a different customer-facing identifier.

The first three digits are an IATA accounting or prefix code used to identify passenger traffic documents. The prefix normally belongs to the ticketing carrier whose ticket stock was used, which may differ from the airline operating a codeshare flight.

You may use the ticket number to retrieve a receipt, check an unused ticket or travel credit, request a refund, claim missing frequent-flyer credit, or help an airline locate a ticket. Some carriers also let you use it for online check-in, but many travelers check in with a PNR or confirmation code instead.

Where to Find Your E-Ticket Number

The best place to find an e-ticket number is the e-ticket receipt or final purchase confirmation sent after ticketing. Airlines use labels such as “Ticket Number,” “Document Number,” “Electronic Ticket,” “eTkt,” or “ETICKET.” The number may appear as 13 continuous digits or with a hyphen after the 3-digit prefix, such as 001-2345678901.

Ticket Number Locations

• E-ticket receipt or purchase confirmation: usually the most reliable source because it records the issued ticket.
• Airline account or app: open the trip, receipt, payment, or ticket-details section rather than relying only on the itinerary screen.
• Cancellation or travel-credit email: airlines may repeat the original ticket number when issuing a credit.
• Credit-card statement: some airlines include a ticket number in the transaction description, although formatting varies.
• Travel-agency itinerary: look for “ticketed,” “document,” or “e-ticket” details. A reservation locator alone is not the ticket number.

If the documents contain several 13-digit numbers, check the label. Paid seats, bags, upgrades, and other extras can be issued as separate Electronic Miscellaneous Documents (EMDs). Those document numbers may look like ticket numbers but are tied to ancillary services rather than the base airfare.

E-Ticket Receipt Details

On an e-ticket receipt, the ticket number usually appears near the passenger name, booking reference, issue date, fare, taxes, payment details, or itinerary. For example, LOT explains that its purchase confirmation labels the 13-digit value as “Ticket number” or “Document number,” while American Airlines directs travelers to the booking email, cancellation email, or card statement.

A receipt from a third-party seller may first show the agency’s booking reference. Search the full document for a ticketed status and 13-digit number. If the agency says the booking is confirmed but no ticket number appears, ask whether the ticket has actually been issued and which airline owns the ticket stock.

Boarding Pass Indicators

A printed or mobile boarding pass may show a ticket number, but many boarding passes display only the passenger name, confirmation code, flight number, seat, boarding group, sequence number, and barcode. Do not assume the 13-digit number will be visible on every pass.

If you already have a boarding pass but need the ticket number for a refund, receipt, or mileage claim, return to the e-ticket receipt, the airline’s trip details, or the original confirmation email. The barcode can contain machine-readable data, but travelers should not rely on decoding it to find a ticket number.

E-Ticket Number vs. PNR vs. Flight Number

These identifiers often appear in the same email, but they serve different purposes. The easiest way to avoid confusion is to match the code to the document or task.

E-Ticket Number Basics

The e-ticket number proves that a specific passenger ticket was issued. It does not by itself tell you whether the flight is on time, which gate to use, or whether you have checked in. Those details come from the live reservation, flight status, and boarding pass.

Each ticketed passenger normally receives a separate ticket number, including an infant when a ticket is required. Several passengers can share one PNR while still holding different ticket numbers.

PNR and Booking Codes

A Passenger Name Record (PNR) is the reservation record containing the itinerary and traveler details. The short code shown to customers is often called a booking reference, confirmation code, or record locator. Many airlines use six characters, but the exact format can vary by carrier and reservation system.

The PNR is often the quickest identifier for managing an active trip. For example, Alaska Airlines describes its confirmation code as six letters and its e-ticket number as the 027 prefix followed by 10 digits. An airline and a travel agency can also create different record locators for the same itinerary, so you may see more than one booking code.

Flight Number Differences

A flight number identifies a scheduled service, not an individual passenger or purchase. It usually combines a two-character airline designator with one to four digits. Hundreds of passengers on the same flight share that flight number, while each ticketed passenger has an individual ticket number.

Codeshares can show both a marketing flight number and an operating flight number. Your ticket’s 3-digit prefix can belong to a third carrier—the ticketing carrier—so do not expect all three airline names or codes to match.

How E-Ticket Numbers Are Formatted

The standard e-ticket number has 13 digits. According to Travelport’s ticketing guide, it contains:

• First 3 digits: the ticketing airline’s code or prefix.
• Next 4 digits: the ticket form number.
• Final 6 digits: the serial number.

Airlines often display the number as XXX-XXXXXXXXXX, using a hyphen only for readability. Examples of verified ticketing prefixes include 001 for American Airlines, 016 for United Airlines, and 027 for Alaska Airlines. The prefix identifies the ticket stock, not necessarily the airline operating every segment.

One ticket document can contain several flight coupons, with each coupon tied to a segment of the itinerary. A multi-city or connecting journey can therefore use one ticket number across several flights. However, separate purchases, separate tickets, long itineraries requiring conjunction tickets, or different ticketing arrangements can create more than one ticket number.

What Information Is on an E-Ticket?

The e-ticket receipt contains more than the ticket number. Exact layouts vary, but most receipts include passenger, itinerary, fare, payment, and ticketing details. The number itself does not “show” those details; it identifies the electronic ticket record where they are stored.

Booking and Passenger Details

• Passenger name: should match the traveler’s identity document as required by the airline.
• Passenger type: may appear as adult, child, or infant, sometimes using codes such as ADT, CHD, or INF.
• Ticket number: the 13-digit document number for that passenger.
• PNR or booking reference: the short code used to retrieve the reservation.
• Issue date and issuing carrier: show when and on whose ticket stock the document was issued.

Review the name and passenger type as soon as the receipt arrives. Name-correction rules vary, and waiting until the airport can make a simple problem harder to resolve.

Flight, Fare, and Fees

The receipt can list the origin and destination, airline, flight number, dates, cabin or booking class, and ticket status for each segment. It may also show the base fare, taxes, carrier-imposed charges, total paid, payment method, and fare calculation.

A fare basis code identifies the fare within an airline’s pricing system. It can help the airline or travel professional locate the applicable rules, but travelers should not assume that one letter has the same meaning on every carrier. Travelport describes a fare basis as an airline-specific identifier for the fare used to issue the ticket.

Baggage information may be shown as a piece allowance, a weight allowance, or a reference to the fare rules. Because baggage benefits can depend on route, cabin, status, credit card, or operating carrier, confirm the current allowance in the airline’s live trip details before departure.

How to Read Your Ticket Details

1. Find the 13-digit ticket number. Look for “Ticket Number,” “Document Number,” or “eTkt.” Do not confuse it with a short PNR.
2. Check the passenger name and type. Make sure the spelling and adult/child/infant category are correct.
3. Review every flight segment. Confirm the dates, airports, marketing airline, operating airline, and flight numbers.
4. Check the ticket status. Terms such as “open,” “confirmed,” “used,” “exchanged,” “refunded,” or “void” describe the document or coupon status.
5. Read the fare and change rules. Look for refundability, change restrictions, advance-purchase rules, and any fees or fare difference.
6. Confirm baggage and paid extras. Separate EMD numbers may apply to bags, seats, or upgrades.
7. Save the latest receipt. After a change or reissue, archive the old document but use the newest ticket number for future requests.

When You Need Your E-Ticket Number

You may be asked for the ticket number when:

• an airline’s check-in or trip-retrieval page accepts an e-ticket number;
• you request a receipt, refund, cancellation review, or travel-credit balance;
• you exchange or reissue an unused ticket;
• you claim missing frequent-flyer miles after a flight;
• you submit a travel-insurance or expense claim;
• an airline or travel agency must locate a ticket after a schedule change;
• you need to distinguish the airfare ticket from separate seat, bag, or upgrade documents.

You do not always need the ticket number for routine trip management. Many airlines use the confirmation code and last name for check-in, seat selection, or changes. Use the identifier requested by the airline’s form rather than forcing the ticket number into a confirmation-code field.

The ticket number identifies what was issued and paid for; the boarding pass is the credential used to pass through the airport and board the flight.

E-Ticket Numbers for Check-In and Boarding

Check-in methods vary by airline. Some carriers let you enter a 13-digit ticket number and surname; others expect a PNR, confirmation code, frequent-flyer account, or travel-document details. For example, United states that travelers can use a 13-digit ticket number during check-in, while American commonly directs customers to a confirmation code for active-trip management.

• Enter the number exactly as the form requests, usually without spaces.
• If the airline prefix is prefilled, enter only the remaining 10 digits.
• If the field asks for a confirmation code, use the short booking reference instead.
• For a codeshare, try the operating airline’s check-in page and use the record locator it recognizes.
• After successful check-in, use the boarding pass—not the e-ticket receipt—to pass security and board.

If online check-in fails, the problem may be unrelated to the ticket number. Passport or visa checks, airport restrictions, special-service requests, traveling with an infant or pet, schedule changes, or an unconfirmed operating-carrier record can require airport assistance.

Common E-Ticket Number Problems

No Ticket Number After Booking

A reservation can be created before the ticket is issued. Check whether payment completed, whether the email says “ticketed,” and whether a final receipt arrived. If you booked through an agency, contact the agency first because it may control the ticketing process.

“Ticket Number Not Found” or “Record Not Found”

• Remove spaces and hyphens unless the form asks for them.
• Confirm that all 13 digits are present.
• Check whether the form prefilled the first three digits.
• Make sure you are using the ticket number for the correct passenger.
• Use the newest number after a reissue or exchange.
• Try the ticketing airline, not only the operating airline.
• Check whether you entered an EMD, travel-credit number, bag-tag number, or PNR by mistake.

Different Numbers on Different Documents

Different numbers are not automatically an error. Each passenger has a separate ticket number, each reissue can create a new number, and paid extras can have separate EMD numbers. A long or separately ticketed itinerary can also include more than one airline ticket.

An agency or GDS printout may show a separate check digit after the 13-digit document number. Consumer airline forms usually ask for the 13-digit ticket number, so follow the field’s example and instructions.

Codeshare and Interline Lookup Problems

Partner airlines may use different PNRs for the same trip. The ticket number can identify the ticket, but the operating carrier may still need its own record locator for seats or check-in. Ask the ticketing airline or agency for the operating carrier’s confirmation code when necessary.

How to Keep Ticket Info Safe

Treat your itinerary and ticket documents as private travel records. A ticket number alone may not be enough to change a booking, but public posts that combine your name, PNR, ticket number, barcode, flight details, and email address can expose information that airline systems use for trip retrieval.

• Do not post boarding passes, confirmation emails, or ticket receipts without covering codes and barcodes.
• Store the receipt in a secure email account, password manager, or protected travel folder.
• Use a unique password and two-factor authentication where available for your airline and email accounts.
• Share the number only with the airline, your authorized travel agent, insurer, employer, or another party that has a legitimate need.
• Watch for unexpected seat, contact, or itinerary changes and contact the airline through its official website or app.

Frequently Asked Questions

What is the format of an e-ticket number?

The standard airline e-ticket number has 13 digits: a 3-digit ticketing-airline prefix, a 4-digit form number, and a 6-digit serial number. It may be printed with a hyphen after the first three digits, but the hyphen is not part of the number.

What is the 13-digit e-ticket number?

It is the document number assigned to an issued airline ticket for one passenger. Airlines and agencies use it to identify the ticket for receipts, refunds, exchanges, credits, and other ticketing work. It is different from the booking reference and flight number.

How do I read an e-ticket?

Start with the ticket number, passenger name, PNR, issue date, and issuing airline. Then review every flight segment, operating carrier, fare and taxes, ticket status, baggage allowance, and change or refund rules. Use the newest receipt after any reissue.

What do J, N, I, C, R, Y, B, and H class fares mean?

There is no universal translation for every airline. J and C commonly appear in business-class inventory, while Y, B, and H commonly appear in economy inventory. I, R, and N vary widely and can represent discounted business, premium economy, upgrade, award, or economy inventory depending on the carrier. Check the airline’s fare rules rather than judging refundability or benefits from the letter alone.

Is an e-ticket number the same as a confirmation number?

No. The e-ticket number is normally 13 digits and identifies an issued ticket. A confirmation number or PNR is a shorter code that identifies the reservation. One PNR can contain several passengers, each with a different ticket number.

Why is my ticket number not on my boarding pass?

Many boarding-pass layouts do not print the ticket number. They focus on check-in and boarding details such as the flight, seat, gate, group, sequence, and barcode. Check the e-ticket receipt, purchase email, airline account, or travel-agency itinerary instead.

Does every passenger have a separate e-ticket number?

Normally, yes. Travelers can share one PNR, but each issued passenger ticket has its own document number. An infant may also have a separate ticket number even when no seat is occupied.

Can an e-ticket number change?

Yes. An exchange or reissue can replace the original ticket with a new ticket number, while the reservation’s PNR may stay the same. Use the latest confirmation or receipt and keep the old number for your records.

Conclusion

Your e-ticket number is the 13-digit identifier for an issued airline ticket—not the reservation code, flight number, or boarding pass. Keep the latest receipt, use the exact identifier requested by the airline, and check for a new number after any exchange. With the ticket number and PNR saved securely, you will be better prepared for check-in, changes, refunds, credits, and post-trip claims.
