I am sure you have had a time in your life when it seems like everyone gives you advice. It might be graduation, marriage, the birth of a child, a change in jobs or something that prompts the people around you to offer advice. Most of the time you are forced to smile pleasantly, act like you are going to take the advice, and then wait until the giver of the advice is out of earshot to mumble to yourself about how you wish people would leave you alone. Occasionally you really need advice and go looking for it. One of those cases might be if you thought that your personal information had been stolen. You would expect that the government that had issued the identity claims would have the best advice on how to fix the problem.
I read an article about the web page at http://www.hmrc.gov.uk/manuals/nimmanual/NIM39140.htm that will tell people in the UK how to handle the case of their National Insurance Number has been abused. (The original article likened the National Insurance Number to the US Social Security Number but whether they are similar or not isn't really important here, just that someone thought you should have a way to report/fix fraud of the National Insurance Number.) The web page has a title that boldly proclaims:
NIM39140 - National Insurance Numbers (NINOs): Format and Security: What to do if you suspect or discover fraud
You can see from the formatting that there are several paragraphs and bullet points that should give you the information that you need. However each and every paragraph and bullet point is replaced by the text:
(This text has been withheld because of exemptions in the Freedom of Information Act 2000)
This leaves you wondering what you should do if you suspect or discover fraud. I haven't looked around to see if there is any information on another web site or if you are just stuck going back to the people who always give you advice and asking for some. This time, however, you will need to listen closely and follow their advice.
