Kkob,This does work what you say about the id number my mates done it no probs at all,but he tried the same idea at the main telephone office on friday he wanted to change his phone and adsl from his turkish mates name into his own name, just using the id number he wrote it down so as not for them to see the actual blue book he had got which had run out,but theyve insisted he takes down the book so they can check that the residencey is still valid,as they will not accept just the number im wondering if all of a sudden theyve recognised a loophole,any ideas.
