London postcode areas
London uses eight postcode areas radiating from the centre (EC and WC), plus the compass-point areas. The sheer density of flats, sub-divided buildings and new-build developments makes manual address entry especially error-prone here.

- Faster checkout and forms for London customers
- PAF-verified addresses cut failed deliveries
