The ebluey site lists BFPO 697 as Mazar-e-Sharif, Afghanistan. According to the list that they have the BFPO number for Kabul is 758. You might like to check the other options by logging on to the ebluey page ( http://www.bfpo.org.uk/ebluey_home.htm ). I was able to find the list of potential BFPO numbers when I went to set up a new address. PM me if you have any hassle finding list.
