It's used fairly extensively in the UK. My extraction script to make post code area maps for the UK [1] applies postcodes to approx 60,000 nodes. It seems to be used most in cities (I suspect those cities put postcode prefixes on street signs). Liverpool has some excellent data for example [2]. I haven't tried applying the same script with addr:postcode yet, so I don't know how it' use compares in the UK, but I doubt it's as extensive as it hasn't been around as long.
