Airport Code Finder

The two worldwide systems are IATA codes (3 letters, e.g. JFK — used on tickets and baggage tags) and ICAO codes (4 letters, e.g. KJFK — used by pilots and air traffic control). In the US you may also see FAA Location Identifiers, which usually match the IATA code for larger airports.

An IATA code is the 3-letter code assigned by the International Air Transport Association to identify airports on tickets, boarding passes and baggage tags — for example LHR for London Heathrow or SIN for Singapore Changi. This finder covers 9,051 airports that have an IATA code.

An ICAO code is the 4-letter code assigned by the International Civil Aviation Organization, used for flight planning and air traffic control — for example EGLL for London Heathrow or WIII for Jakarta Soekarno-Hatta. You can search this tool by ICAO code as well.

Type your city or airport name into the search box above — for example "chicago", "changi" or "denver" — and the tool instantly lists matching airports with their IATA and ICAO codes.

London is served by six airports with IATA codes: LHR (Heathrow), LGW (Gatwick), STN (Stansted), LTN (Luton), LCY (London City) and SEN (Southend). Search "london" above to see them all with details.

New York City is served by JFK (John F. Kennedy), EWR (Newark Liberty) and LGA (LaGuardia). Search "new york" above for full details on each.

9,051 airports with official IATA codes, sourced from the OurAirports public-domain dataset and covering 239 countries and territories — more than twice the 4,401 airports listed by airportcodeguide.com.

Yes — completely free, no signup, no limits, and it runs entirely in your browser.

No map — instead every airport result shows exact latitude/longitude coordinates you can paste straight into Google Maps or any map app, plus elevation and a great-circle distance calculator between any two airports.

It computes the great-circle (shortest path over the Earth) distance with the haversine formula using the IUGG mean Earth radius (6,371.0088 km). For example JFK to LHR is about 5,540 km. Real flight routes are slightly longer because of airways and winds.

FAA Location Identifiers are assigned by the US Federal Aviation Administration. For most larger US airports the FAA code matches the IATA code (e.g. JFK). Smaller US airfields may have an FAA code but no IATA code — those are not in this database, which only lists airports with IATA codes.

Yes. Type the 4-letter ICAO code (for example EGLL or WSSS) into the search box and the matching airport appears first.

No. Your location is read by your own browser's geolocation API and never leaves your device — the nearest-airport calculation happens locally, and nothing is uploaded or stored.

Large metro areas are served by several airports, each with its own code — for example Chicago has ORD (O'Hare) and MDW (Midway), and Tokyo has HND (Haneda) and NRT (Narita). Search the city name to see every airport serving it.

The dataset is derived from OurAirports (ourairports.com), released into the public domain, filtered to the 9,051 airports that hold an official IATA code. Coordinates and elevations come from the same source.

Not with this tool — and that's deliberate. Turning a street address into coordinates (geocoding) requires a server API, and this finder is 100% offline with no server. Instead, search by the city name: type "houston", "denver" or "orlando" and you'll see every airport serving that city.

Yes. Run any search and click Download as CSV above the results — the file opens directly in Excel, Google Sheets or any spreadsheet app, with IATA, ICAO, name, city, country, coordinates and elevation columns.
