Citi Security SMS

We will alert you by SMS if we identify suspicious activity on your debit card purchases. This enables you to reply instantly to 65151 (or +447860065151 if a non-UK mobile number) and confirm whether the purchase is genuine or fraudulent, 24/7. If you reply recognising the activity we messaged you about then you can continue to use your card as normal. If you don’t recognise the suspicious activity then we will take immediate action to secure your debit card.
