It will almost certainly share a postcode with at least one neighbouring 
property, yes. A filling station is not going to receive enough post to 
justify a "large user" postcode. So if it's surrounded by properties 
that all have the same postcode, then that's definite enough. But if one 
neighbour has one postcode, and a different neighbour has a different 
one, then we can't be certain which is correct for this property... :-)
