To pick up passengers at Heathrow Terminal 5, the most reliable postcode to use for satellite navigation is TW6 2GA. This postcode will direct you to the Short Stay Car Park, which is the official designated area for picking up arrivals. Heathrow strictly prohibits picking up passengers from the terminal forecourts for security and traffic reasons; any vehicle caught doing so may face a hefty fine. The Short Stay Car Park is conveniently located just a short walk from the arrivals hall via covered walkways. If you are using the "Wait & Free" service or the Long Stay car park for a more budget-friendly option (free for up to 30 minutes), you should instead use the postcode TW6 2RL. In 2026, it is always wise to double-check for any temporary diversions around the Western Perimeter Road, but TW6 2GA remains the primary address for the multi-story car park directly adjacent to the terminal.
