There have been several reports of Identity theft where persons have been using addresses to obtain car Insurance. We can only assume that they are getting a lower rate because of the post code area or getting credit to obtain such as the addresses used are likely to have a good credit score rating.
These person are possibly using their own names but the addresses they are using are selected at random.
It is believed that they are not local and could be from anywhere in the UK. A majority of the names on the letters are Eastern European sounding.
If you receive any letters of this nature can I ask that you report the matter to Action Fraud, details of how to do this can be obtained on the below link.
