I doubt it, SpaceCase. I'm sure you are just winding Meg888 up, but of course the information is printed on cheques and more importantly is easily found using Google - just key in any sortcode and lots of entries come up showing the bank address, so I doubt a fraudster would need to go on AB.
But the only people who ask these questions are green newbies who presumably sign up just to ask a sort code query. I am sure the information is usually of no use whatsoever, and no-one has yet convinced me otherwise.
The only valid reason i can see is if you are filling in a DD mandate the form acts for your bank sortcode and bank address (which puzzles me as most if not all processing is done centrallly not at the branch).
