Roads filed under AB21

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 AB21

What does an AB21 postcode tell you?

That the address lies in the AB21 district of the AB (Aberdeen) postcode area, and the place OS Open Names most often lists first for its postcodes is Aberdeen. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 825 live postcodes.
