Roads filed under HP16

Named roads first, then numbered ones. A road is filed under one district even where it runs through several, so a street missing here may be listed under a neighbouring district — which is why the address lookup never calls a British street absent. Great Britain has no open register of buildings, so a listed road never means a building on it exists.

Common questions about HP16

What does an HP16 postcode tell you?

That the address lies in the HP16 district of the HP (Hemel Hempstead) postcode area, and the place OS Open Names most often lists first for its postcodes is Prestwood. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 372 live postcodes.
