Hi there I have applied for a credit card and I have put in my old address when I was applying for my credit card would it come 2 my new address? 

Hi @MaxWeir77, thanks for getting in touch. Have you updated your address with us? If not, the card will be posted to the address we have on file. Please call us on the number on the original post and my colleagues will be able to double check this for you - Caroline

I have moved to Ireland and only have an Irish mobile not a UK one. The website won't accept my mobile number. What to do? I am now potentially going to be locked out of my online banking. Should I close my account?

Hi there, we can only send texts to UK mobile number so your other option would be sending any security codes you might need via the post. Are you locked out of your online banking at the moment? - Alex

Hi Alex, no I am not locked out as yet, because I am on my usual PC at home. If I were to replace the PC in the future I would not be able to access my online banking without the mobile phone. I have switched to paper statements from paperless as if this happened I would not be able to view and pay my monthly statement.

Also I am unable to delete the old UK number which no longer belongs to me.

I am thinking I may need to close my Tesco account and just use my Irish cards which is annoying as I have a small UK pension paid in sterling into a UK bank account and it is handy to be able to make purchases in the UK in sterling without losing out by exchanging money to and from euro.


If you fill the box with 0s you should be able to delete the old number. Sadly it may cause you some bother if you aren't able to receive your texts for security checks when using the account and online banking - Alex

Hi Alex, Sorry, I tried that but it says that **sensitive info removed**0 is not a valid phone number and won't accept it.

If you give us a call we'll get that sorted, sorry it's not doing it online. You can reach us on +44 1268 50 80 27 - Alex

OK, thanks for your help Alex

Hi. I have followed the procedure to change my address, and still doesn't work, I have this message: " We're sorry. Something went wrong and we were unable to complete your request."
I don't want any letters to go to my old address. How can this be sorted out?
