FAA airport identifier lookup.

Worked example: John F. Kennedy International

Search JFK. The FAA record gives FAA identifier JFK and ICAO identifier KJFK, in Queens County, New York, at a field elevation of 13 ft with a control tower. It lists four runways: 04L/22R (12,079 ft by 200 ft, concrete), 04R/22L (8,400 ft, asphalt), 13L/31R (10,000 ft, concrete) and 13R/31L (14,511 ft, concrete). The longest runway is therefore 14,511 ft. A small field works the same way: 1G3 is Kent State University airport in Kent, Ohio, with one 4,000 ft runway and no tower.

How the identifiers work

The FAA location identifier (LID) is the code used in FAA records. It is 3 to 4 characters and may contain digits, as in 1G3. The ICAO code is a 4-letter international code. For most U.S. airports that have one it is the letter K plus the FAA identifier, such as KJFK, but the FAA lists an ICAO code for only about half of the airports here, so this tool never guesses one. IATA airline codes are not part of the FAA data and are not searchable here.

About this data

Records come from the FAA National Airspace System Resource (NASR) 28-day subscription, APT CSV files (APT_BASE.csv and APT_RWY.csv), effective 3 September 2026 and published by the FAA at faa.gov NASR Subscription (file 03_Sep_2026_APT_CSV.zip). Only airports with status open and public use are included; private-use airports, heliports, seaplane bases and other facility types are left out. Lengths and widths are feet and elevations are feet above sea level, as the FAA publishes them. This page is a static snapshot: the FAA issues a new cycle every 28 days, so runways, closures and identifiers can change after the date shown.

This is a reference lookup, not a flight-planning source. Use current FAA charts, the Chart Supplement and NOTAMs before flying. The lookup runs entirely in your browser and nothing you type is stored or sent.

FAQ

What is the difference between an FAA identifier and an ICAO code?

The FAA identifier (LID) is the code in FAA records, such as JFK or 1G3. The ICAO code is the four-letter international code, such as KJFK. Search either one.

Why does my IATA code return nothing?

IATA codes are not in the FAA NASR data. At many large airports the IATA code equals the FAA identifier, so try that, or search the city name.

Why is a private airstrip or heliport missing?

Only open, public-use airports are listed. Private-use airports and heliports are excluded to keep the page small and the data meaningful for the public.
