Everyone would give the full postal code as their address. But some websites
and surveys ask for just the first half, as this is good for statistics but
keeps enough privacy.
A few times I have written letters (to friends as a kid) where I forgot the
postcode and put "AB12 ???", but they should get it from the full address,
Royal Mail is just anal that you put the post code on.
If you're clever (or find it fun), you can recognise the place from the
first two letters. TW = near the Twickenham sorting office. DH = Durham City
(possibly covers the whole county actually).
This map is interesting, especially with changing the layers to see
different crowd sourced data sources.
