Very grey area. Certainly the co-ordinates returned by a Google Maps
search for a UK delivery point will be copyright Royal Mail, a dataset
which Google will licence, and pay a really hefty fee for it - after
all, it does make their commercial website very useful. Don't do that.
It's not beyond commercial greed for a nosey parker in Royal Mail to
compare FreeThePostcode's postcode co-ordinates against theirs, and try
to sue a non-profit organisation.
I'm also convinced that there's Easter Eggs in the Royal Mail Address
Manager / Royal Mail PAF dataset.
The business listings for the theatre school in Google will probably
come from a commercial business directory, which Google either licence,
or crawl across the theatre school's web site, and take it from there.
Again, that commercial business directory, displayed in the top links of
Google searches may well have misinformation, and easter eggs, to catch
My guidance is that if you have found the theatre school's own web site,
and you find their postcode on that under contact details; and you
happen to personally know where it is on a map, then that postcode is
fair game.. BUT..
Openstreetmap map data is creative commons - SA licenced.
Freethepostcode is public domain.
There's a niggling issue with the licencing of your work derived from a
CC:SA licence to a public domain licence, which is why a similar
project, www.npemap.org.uk doesn't use openstreetmap as a backdrop, but
an out-of-copyright ordnance survey map.
