I'm sorry to hear you're having these issues, it might be best you give us a quick call and we can look into this further for you. You can reach our Online Helpdesk on 0345 300 3511 (24/7) and one of my colleagues will be able to assist – Clare

I can't sign in on desktop because it's asking for an old number. I've called three different numbers all ask if I want to speak to support so I say yes, then it just says "sorry we can't help any further" and cuts off.

- The "Not the right contact number? Let us know" button just goes to the help page but provides zero help regarding this.
- I can't change my number in the app.
- I can't get any support on the phone.
- There is no live chat support.

What should I do? How are people supposed to get help when needed? What support is actually offered by Tesco Bank?

Hi @zamp, I'm sorry to hear about that. Can you please confirm what number you've called? If you give our Online Helpdesk a call on 0345 300 3511 (Mon -Sun 8am - 7:30pm) they can update your number for you so you can log in straight away.


If you're not in a hurry to access your account, I can send you a Temporary Security Number in the post which will reset your online banking and allow you to get logged in again. This can take between 3-5 business days to arrive and will be valid for 30 days. Once logged in you can update your phone number, I've included a link below with details on how to do this. If you'd like this option, please send a private message to @Tesco-Bank - Caroline
