Ok, so the PAF changes, but what changes? Surely Postcodes aren't reassigned? If my street has been assigned a postcode, they're not going to assign that same postcode to another street, are they? It's common to assign a new postcode to an old address, and it's trivial that new addresses are assigned new postcodes. Neither of those activities would make existing data inaccurate (except for reverse lookups - location to postcode). If postcodes aren't reassigned, then it's OK to use those postcodes as keys in a database lookup. > Just as really old ordnance survey maps (well older than me) are > becoming out of copyright and can be used. > > -- > Francis Davey > > _______________________________________________ > Mailing list [email protected] > Archive, settings, or unsubscribe: > https://secure.mysociety.org/admin/lists/mailman/listinfo/developers-public -- Ian Eiloart _______________________________________________ Mailing list [email protected] Archive, settings, or unsubscribe: https://secure.mysociety.org/admin/lists/mailman/listinfo/developers-public
