Airport code lookup
Type a code - LHR, EGKK, or whatever is on the mug - and get the airport it belongs to, the other code it carries, and the coordinates. Every UK and Irish airfield is here, plus the major airports worldwide.
Airport data from OurAirports (public domain), read 2026-09-08. This list carries every UK and Ireland airfield with an IATA code (whatever its size) and every large scheduled-service airport worldwide.
Where a code matches nothing here, the tool says so rather than guessing. Some small airfields share a municipality name - pick from the list when that happens.
Two codes, two jobs
Most airports carry two codes, and they are not interchangeable. The short one belongs to IATA: a unique three-letter code that identifies a location like an airport on tickets and baggage tags - the one on the print. The long one is the ICAO location indicator, the four-letter code that goes in the box on an international flight plan; FAA guidance tells filers to use the four-letter LOCID whenever available, and its regional prefixes are why every British one starts EG.
That is also why the tool takes either: type the three letters you know from flying, or the four you know from the chart, and the same airport comes back.
What the coordinates line is for
Each result carries the airport's position to four decimal places, which is the same line the airport-code print sets beneath the code: the code huge in navy, the airport name, and the coordinates beneath it. The personalise page fills that layout from whatever you type, and this tool exists so nobody has to look the pieces up one at a time.
For what the codes mean and why one of them ends up on a wall, what is an airport code carries the sourced answer; the airport code print is the thing it prints onto.
The rows come from OurAirports' open data, which its publishers release into the public domain, read 2026-09-08. The UK and Ireland list is complete down to the smallest airfield that carries an IATA code; worldwide, the tool carries the large scheduled-service airports, because that is where a code on a boarding pass comes from.
Airports carry two codes, not one: IATA's three-letter location identifier for the commercial side, and the four-letter ICAO indicator for flight plans. The tool takes either, and shows both.

The briefing
Questions, answered
What is the difference between the IATA and ICAO code?
+
The IATA code is the three-letter one you see when you book - LHR, MAN, DUB. The ICAO code is the four-letter one that goes on flight plans - EGLL, EGCC, EIDW. Both are shown for every result, and the tool accepts either as the search.
Which airports are in this lookup?
+
Every UK and Ireland airfield with an IATA code, from Heathrow down to the smallest strip - 112 of them - plus the large scheduled-service airports worldwide. The data is OurAirports open data, in the public domain, read September 2026.
Why does my small local airfield not appear?
+
If it has no IATA code, it is not on this list - plenty of small airfields carry only an ICAO-style ident or nothing at all. Where the tool says "not on this list" it means exactly that: nothing here matched, and it will not guess at a near match.
Can I put the result on a print?
+
Yes. The airport-code print sets the code huge in navy with the airport name and coordinates beneath. The result card links straight to the personalise page.
