An accurate address helps your order reach you without delay. The key thing to get right: give the delivery address, not the building's headline address.
The details that make up an address
A complete address includes:
Name — a recognisable label for the address, such as "York House".
Street number — such as 51, 1, or 13. It can be a unit number (such as "Unit 2"), and it may be left empty when there's only a flat number or office/room number instead.
Street name — such as Bryanston Street or Angel Lane.
City — such as London.
Postcode — your full postcode, including both halves (for example EC1A 1BB).
Country — such as United Kingdom.
Address details — any extra detail, such as the floor or building (for example "Floor 2, York House").
Courier instructions — anything the courier needs to know, such as "Enter via York House loading bay".
Map pin (latitude and longitude) — set by dragging the pin on the map. Drop it on the exact point where the courier should arrive, not just the middle of the building.
Give the delivery point, not the building
Use the spot where the delivery is actually made, rather than the building's main address. For example, if a building's headline address is on the main road but deliveries go to a loading bay round the side with its own address, use the loading bay address, and put the map pin on that entrance.
