I have been out all day but just seen this thread. I will apologise morgan23 for the tone of my initial posting. I have answered many postings about sort codes and I think every one has been from a new AB member and 95% have never acknowledged the help we Answerbankers give.
Also I and others have queried what possible use the info could be, but 95% of the time the poster never enlightens us. Some suggest the requests are from either fraudsters or the cash machine equivalent of trainspotters- I've never said that but I have queried what possible use the info is.
I have also wondered why anone takes the troubl to sign up to AB to ask a question that can be answered more easily by your bank or via Google.
If there is a fraud I think you should ask your bank or ask lloyds. I'm puzled as to what use the branch address is to you in chasing up a fraud. You don't have to tell us, of course, but I'd be really interested to know, so I may be more inclined to help others in future with sort code queries.
Anyway, sorry if I got the tone wrong and tarred you with the same brush as most other green newbie sort code query posters who, to me (as I'm a pretensious berk), are generally time wasters in my view.
