The only one published seems to be an 0845 which turns out to be the same for all branhces !  You used to be able to at least ring an 'area' number. How ridiculous. Have tried a very old geo number I found but it sounds like it has been turned over to a fax line. Thanks fellow 'saynoto's'' :)

Please can you supply basic information rather than leaving us to do the spadework and guess as to what you haven't told us?

What is the 0845 number for the branch you are looking for?
What is the full address (including post code) of the branch you are looking for an alternative for? (The Barclays website may help with this)
What is the "old" geographical number that is now answered by a fax machine?

I am so sorry for not being more expansive in my request. I assumed anyone knowing this number woudld be local to it and tried to keep things brief !
I do  not expect others to do 'spadework' for me, was not expecting an instantaneous reply  and dont appreciate your presumption.  I have in the past added numbers to try to help others sidestep expensive calls. This is my first number request.
However since you ask the address is
Barclays Bank, 66 Market Place, Chippenham, wilts SN15 3JA and the old geo number I tried was 01249 656246 but actually it was extremely old and found in an old address book. I didnt hold out much hope for it.
The number on the website, as stated, seems to be the same for most others and is 08457555555.

Found  01793 583300 here http://www.shoplocally.co.uk/localads.asp?catid=097009014.

It`s a Swindon no. so possibly a main switchboard but may be able to transfer you to Chippenham.
