Non-UK address
For addresses outside the UK you should choose the option 'I have a non-UK
address' and you will then be able to enter full details of your address.
UK addresses include those in England, Scotland, Wales, Northern Ireland,
Channel Isles and Isle of Man.
For addresses in the UK you should enter your house name or number and
postcode and choose the option 'Find my address'.
For British Forces Post Office (BFPO) addresses you will need to take the
following steps to change your address: Do not make any entries in the boxes
on this page. Instead, select 'I don't know the postcode'. You will need to
enter a character in each of the three boxes on the next page e.g. a, b and c,
then select 'Find my address'. The page will then display a link to 'enter
address manually', which will allow you to enter your BFPO address. Leave the
Postcode box blank.
