So I would not say they are "popular". More like "essential".
Can you specify how do you expect this to work. Do you just type in the postcode and get coordinates to drive to? Or do you specify post code and some additional information?

Having a mapping between postcodes -> coordinates is "simple". So, driving on the basis of postcodes only.

Having a mapping between postcodes and some extra data is harder. Not sure how to do that properly yet
