Surely if you have your Kimlik (residency, blue book) your are wanting a NUFUS number which is your population number to prove you are resident in the area you live. If you cant get it on line you do need to go back to the Council office and to room 2. You need your Kimlik(blue book) and possibly your passport. They can do it straight away. If you still have a problem ask the nice gentleman at the Passport Police office ,explain the problem, and he should be able to look it up for you if he is not busy.
