Is the ANZ BANK PLC really exist in London, UK, 1 Market street, BD1 1EG England ?

There is no London postcode that begins with BD - all postcodes relate to the area ie SW is South West, EC is East Central etc. If you've received this out of the blue, it's a scam - bin it, and anything like this you get.

1) Try ANZ sites for confirmatiom

2) If you're asking because you've got a message 'out of the blue' which says you've got money or a chance at money - but they need your account number - Delete it!
It is a scam! Don't even reply, or they may be able to hook-on to your internet and track your dealings!

Just saw Sarah's answer. If that doesn't confirm it to you - I'll be sorry for you, if you end up losing money!!
I agree with the other answers, although BD refers to Bradford I believe which has several bank's processing offices..saying that, I've never heard of an ANZ Bank..bound to be a fraud
