I had an email today saying it should be here and to request a new one but if I do this and the original one turns up tomorrow will that pin be void?
It just said it was incorrect, I did a trouble shoot which just said request a new one
Give it a few more days. If it doesn't come try to use the Verification Troubleshooter.
Select the big red "Contact Us" button and then "I'm having Problems Verifying My Listing(s)"
I'm almost positive that works in the UK
