Firstly that's specific to how a particular region encodes its postal coding, which isn't worldwide.
Secondly, it's less true than you'd think within the UK. From http://en.wikipedia.org/wiki/File:London_postcodes.png http://en.wikipedia.org/wiki/File:London_postcodes.png, compare the locations of W2 and W3 or W12 and W13.
- a3camero 15y agoI agree. Canada uses a concept of FSAs (forward sortation areas) that correspond to regions. I don't think it's safe to rely on truncation under the Canadian postal system. I believe only the first three letters/numbers identify a geographic area, and this is the triple used by politicians and people who need to split up regions of provinces. As you might expect, FSAs are way smaller in major cities than out in rural areas.
