What Does an Airport Gate Number Mean?
An airport gate number identifies the boarding or arrival location assigned to a flight within the airport. Gate labels can contain numbers, letters or both, and their format depends on the airport’s terminal and concourse layout.
What do the letters and numbers mean?
A letter may identify a terminal, concourse, pier or gate area, while the number identifies a specific gate within that area. There is no universal naming system, so the meaning of a label such as B12 or D29 depends on the airport.
Is the gate number the same as the terminal?
No. The terminal is a larger airport area, while the gate is the specific location used for boarding or arriving. Some airports also use concourse names or letters between the terminal and gate level.
How do I find a gate inside the airport?
Confirm the current terminal and gate, then follow airport signs for the appropriate terminal, concourse and gate range. Large airports may require trains, moving walkways, buses or long walks between areas.
Why is there no gate number yet?
A gate may be blank or shown as TBD when an assignment has not yet been published to the information source you are checking. Keep checking as departure or arrival gets closer.
Can the gate number change?
Yes. Gate assignments can change as airport and airline operations develop. An earlier boarding pass or flight search can therefore show a different gate from the latest airport display.
Can two airports use the same gate number?
Yes. Gate numbers are local to each airport. Gate B12 at one airport has no relationship to gate B12 at another airport.
Always confirm the latest gate
Use the flight number and travel date to check the latest available assignment, then confirm important last-minute changes with the operating airline and airport displays.

What Travelers Should Know
Gate numbers identify boarding locations
A gate number points passengers to the specific airport boarding position assigned to a flight. The format may combine a concourse letter with a number, such as B12.
Numbers are airport-specific
Gate 12 at one terminal has no relationship to Gate 12 at another airport. Always pair the gate with the correct airport and terminal or concourse.
Treat the assignment as changeable
Gate numbers are operational assignments, not permanent parts of a flight. Check again near boarding because airlines and airports can move a flight to another available gate.
