Short answer. An airline PNR is a six-character code made of capital letters and digits, such as Q7XK2M (made up for this page). It is printed near the top of your booking confirmation. It is not the 13-digit ticket number, and on its own it proves nothing, because any six characters look the same.
Key points
- Airline PNR format: six characters, letters and digits mixed.
- It goes by several names: booking reference, confirmation code, record locator.
- The ticket number is different: 13 digits, starting with the airline’s code.
- A train PNR from Indian Railways is a 10-digit number from an unrelated system.
- The only way to check a PNR is to look it up on the operating airline’s website.
What does an airline PNR look like?
Six characters, all capitals, mixing letters and digits. Some made-up examples in the right shape:
| Example | What it is |
|---|---|
Q7XK2M |
Airline booking reference (PNR / record locator) |
HB4TZR |
Also a booking reference; some are all letters |
125-2345678901 |
Not a PNR. A 13-digit ticket number (125 is British Airways’ code) |
4512378906 |
Not an airline PNR. The shape of an Indian Railways PNR (10 digits) |
None of these point at an actual booking. They show the format only.
Where do you find your PNR?
Look near the top of the confirmation email from the airline or the booking site. The label varies: booking reference, confirmation number, record locator, reservation code or simply PNR. The same code appears on the e-ticket receipt, and most airlines print it on the boarding pass as well.
If you booked through an agent or an online travel site, you may see two references: the agent’s and the airline’s. The airline’s own reference is the one its Manage Booking page accepts. If one code does not work on the airline’s site, look for the other one in the confirmation, or ask the agent for the airline reference.
PNR vs ticket number vs flight number
Three different things are often confused:
- PNR / booking reference. Six characters. Points at the booking record. Exists as soon as seats are held, even before payment.
- Ticket number. 13 digits. The first three identify the airline (001 is American Airlines, 125 is British Airways, 176 is Emirates). Exists only once the ticket is issued. See how to read an e-ticket receipt.
- Flight number. The airline’s two-character code plus up to four digits. It identifies the flight, which hundreds of passengers share, not your booking.
Why is a train PNR a different length?
Because it comes from a different system. Indian Railways calls its booking number a PNR too, and it is 10 digits long. The name is shared with airlines, but nothing else is: the format, the system and where you check it are all separate. Many searches for a PNR number example are really about train tickets, which is why the two are often mixed up.
Does a PNR in the right format mean a booking exists?
No. The format has no check digit, signature or pattern that separates a live booking from six random characters. Anyone can type a code that looks correct.
The only test is a lookup. Enter the reference and the passenger surname on the operating airline’s Manage Booking page. If flights appear, a booking exists in that airline’s system. If nothing appears, it does not, or the reference belongs to an agent’s system instead. See what a PNR actually is for where the record lives.
How does this relate to a sample itinerary?
A sample itinerary from this site creates no booking, so it has no PNR. Instead of a six-character code, the document shows DEMO REFERENCE and states that no reservation was created, so it cannot be mistaken for a booking reference. If you need something an airline can look up, see held and refundable bookings.
