Personally, I know the postcodes of all of my adjacent villages and I've 
never looked-it up on any website. You "just know" from personal 
knowledge, conversation, local stores. Of course I haven't surveyed all 
the houses, but you suppose the postcode to be true for all the houses of 
the village.

I mean, a friend could tell me: "Hey, send me a postcard; I live in 
wonderland and my postcode is 1337", then I would think: "Okay, the 
postcode for wonderland is 1337". What's wrong/illegal/not acceptable with 
that ?

It's empiric and not "real science", but it works.
