Which prefixes correspond to the United Kingdom and Ireland in ICAO codes?

In ICAO codes, the first two letters indicate the country. The United Kingdom uses the prefix EG, so airports there begin with EG (for example, London Heathrow is EGLL). Ireland uses the prefix EI, so Irish airports begin with EI (for example, Dublin is EIDW). That’s why United Kingdom: EG and Ireland: EI is the correct pairing.

EK corresponds to Denmark, EN to Norway, and EIIR would not be a standard Irish country prefix, since Ireland’s prefix is EI and airport codes there follow EI plus two additional letters (like EIDW, EICK).
