Are you already a victim?

Act quickly to make sure that you are not liable for financial losses caused by criminals using your identity.
Report lost or stolen documents, such as passports, driving licences, credit cards and cheque books to the organisation that issued them.
Consider contacting the CIFAS – the UK’s Fraud Prevention Service - to apply for protective registration if you believe you are a victim of identity fraud or at risk of becoming one, once you have registered, CIFAS members will carry out extra checks whenever anyone, including you, applies for a financial service using your address. They do this to make sure that a criminal is not trying to commit fraud by pretending to be you. You will have to pay a charge for this service.
If someone fraudulently opened an account in your name, contact the company concerned immediately.
Contact your bank or credit-card company to report suspicious transactions on your statement.
Get a copy of your personal credit file and report any suspicious entries. Report the matter to your local police and ask for a crime reference number.
