How do I update my mobile phone number?

You can update your mobile phone number by calling us on 0800 008 008*, +44 1604 269452* from outside the UK (24/7) or contacting your Barclaycard Relationship Manager. Barclaycard Business card customers can also update their details by logging into their online servicing account.  

If you have recently updated your mobile number with us, then you may not be able to use the new mobile number for authentication straight away. For security reasons, it could take up to seven business days for the new mobile number to be registered to your account for verification use.
