How this service works
Convert an airport code between IATA (3 letters) and ICAO (4 letters) and validate the format; reports unknown codes.
Output
Returns both the IATA and ICAO codes for the airport, a format validity flag, a verdict on whether the code is known, a human-readable summary, detailed airport metadata (name, type, lat/lon, country, region, municipality, elevation in meters and feet, scheduled service status), the input code echo, input kind (IATA or ICAO), and source/attribution fields. If the code is unknown or malformed, the verdict and reasons fields reflect that.
Example use cases
Flight plan ICAO code lookup
“I'm filing a flight plan and need the ICAO code for Dallas Fort Worth — I only have the IATA code DFW. Can you convert it?”
Validate passenger itinerary code
“A booking system returned the airport code 'KSFO' — is that a valid ICAO code, and what's the matching IATA code?”
Normalize mixed-format airport data
“I have a dataset with a mix of IATA and ICAO codes, starting with EGLL — can you tell me what IATA code that maps to and confirm the format is valid?”
Technical details
Endpoint
GEThttps://airports-reference.x402tookit.com/airport-code-convert?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to convert between IATA and ICAO airport code formats, validate whether a given code is correctly formatted and recognized, or retrieve basic airport metadata keyed by either code type. It is purpose-built for code-format translation and validation, unlike a general airport search endpoint which is better suited for fuzzy name matching or discovery.
Side effects
- Unknown code: code passes format validation but is not found in the dataset — verdict reflects 'unknown', iata/icao fields may be null
- Invalid format: code does not match IATA (3 letters) or ICAO (4 letters) pattern — formatValid returns false
- Missing required parameter: omitting the 'code' query parameter results in an error response
- Ambiguous or non-airport ICAO prefix: some valid-format codes may not correspond to civilian airports
