How do I report a lost or stolen card?

If a customer has lost or had their card stolen, it is crucial to act quickly to prevent unauthorized transactions. Citibank UK has specific procedures in place for reporting lost or stolen cards. Typically, customers can report their lost or stolen cards through the customer service number provided on their website. They may also have the option to report the issue through their online banking platform or mobile application, if they have access to those services. Once the report is made, Citibank UK will take steps to block the card and issue a replacement. It is advisable that the customer checks the current web page for the most accurate contact information and guidance on the reporting process. Taking prompt action helps protect both the customer and Citibank UK from potential fraud.
