You can do up to 6 in Canada. Nobody ever told me, but when I was signing up at RBC I accidentally typed 5 and it worked. Now I know why they don't deterministically say 'OK, he's done' after you hit four digits.

Watch out! I also live in Canada, and a close friend of mine while travelling was frozen out of his accounts because there were no banks that could handle 6 digit pins there.

For that reason I recommend having a 4 digit pin.

Where's "there"? (Presumably not Canada?)

I couldn't use a 6 digit pin in Italy. Some ATMs in London,UK didn't like it either.

Singapore it's mandatory for a 6 digit pin so have no idea if a 4 digit pin will work, anybody been there?
