The primary postcode for London Heathrow Terminal 2 (The Queen's Terminal) is TW6 1EW. This postcode is essential for GPS navigation, ride-hailing apps like Uber or Bolt, and for sending mail to terminal-based offices. If you are being picked up or dropped off at the "Arrivals" level, this postcode will direct you to the main terminal complex. However, for those using the Short Stay Car Park 2, which is most convenient for meeting arriving passengers, the postcode is often listed as TW6 1RR. In 2026, travelers should be aware that Heathrow sits within the Ultra Low Emission Zone (ULEZ), meaning any vehicle entering the airport area must meet specific emission standards or pay a daily charge. When inputting the postcode into a sat-nav, always ensure you follow the specific "Terminal 2" signage once on the airport perimeter roads, as the "TW6" sector covers a vast area including cargo centers and maintenance hangars.
