Thanks Johnny - I was looking in the wrong place!
I am presuming that the post must have been intercepted somehow as I would have thought that she would have received things through the post unless the impersonater put down a 'mail drop' address.
Whilst no one has ever applied for credit in my name, my credit card details have been used on two occasions - once in 1987 and once in 2005. Both times, Lloyds TSB were excellent at sorting out that it wasn't me who had used it.
The last time I had problems, I did report it to the police and was advised to take out a CIFAS subscription. This effectively means that it is not easy for anyone to get credit in your name as you have to jump through a few more hoops.
It won't be relevant to most people who post on here, but I'll post the link anyway:
