I signed up with Monzo app and I completed all my info 2 days ago. But now I need to change my delivery PO address and my address info due to COVID-19 reasons, but I can’t login to my account, view my account information or chat with your help Center.
There are no buttons except the card Activation button.
The app shows only this :
it looks like its too late to change the address now, if will be in the mail already
Been a while since I got my card, but was standard letter size, maybe 1cm thick, I don’t recall it requiring a signature(although that’s not done now due to covid anyway)
I doubt they will give you the card number, the delivery process is probably part of the security(it’s proof you can receive mail at the address, prevents id theft)
