Business Cards:
Are  your Cardholder contact details up-to-date?
We’re  updating the way we authenticate online card payments by adding an additional  layer of security to protect your business and help fight fraud – this is  called Strong Customer Authentication (SCA).
It’s  important that we hold the correct mobile phone number for all Cardholders on  your card account. Without this information, transactions may be declined, as  we won’t be able to send a One-Time Passcode (OTP) to the Cardholder’s mobile  phone to authenticate online payments.
What  you need to do now
Please  can you make sure all Cardholders check and update their mobile phone number by  calling us on 03455 873 874* (for security and fraud prevention  reasons, we’ll need to speak directly with the Cardholder whose details we’re  updating).
*  We’re open Monday to Friday 8am to 6pm. We may monitor and/or record your calls  for security and service improvement purposes. If you’re calling from outside  the UK please dial +44 1226 260 876. If you need a Text Relay service, you can  download the ‘Relay UK’ app and call our number from within it. For other  accessible ways to contact us, please visit: ciiom.hsbc.com/accessibility.
