We Swedes don't have post offices anymore. They were closed last year in an effort to save money. Yes, really! Now we have a rudimentary mail service at shops instead.
Postal codes are five digit: XXX XX. 1X XXX is the Stockholm area and for each digit it zooms in on an area. With all digits in place, you're down to just a few streets.
Paul,
opening a bank account isn't very hard. I have three, two of which I don't know the number of. Each time I have to hand the teller my driver's license and ask him/her to find the account number for me.
