Missing data for some location in UK

[Hoàng Ngọc Tuấn Anh]

Hello,

I'm using Google maps Javascript API to help my users search their address easily. However, for some location in UK, they cannot find their house.

For example: For post code ST8 7LF I can find 4 houses by searching on www.royalmail.com/find-a-postcode, but Google data has very minimal details data

I know that to improve the precision of data, we need lots of time, but in such case, how can I improve my user experience ?

Thanks!

Google doesn't use Royal Mail PAF data to provide addresses: a postcode
is located on its centroid.

What I've done to improve the user experience is to show Google's
identified location on a map with a draggable marker which the user can
move to a better place.

But there's no way that Google will provide a list of addresses having
any particular postcode. Even reverse geocoding is only done by
interpolation: if Google can return an address for a location, it's only
a guess (and certainly not based on postcode).
