Roads filed under BN17

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 BN17

What does a BN17 postcode tell you?

That the address lies in the BN17 district of the BN (Brighton) postcode area, and the place OS Open Names most often lists first for its postcodes is Littlehampton. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 768 live postcodes.
