Hi Paul Gleeson
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
If you've already signed up for an Azure free account with any of your email addresses or credit cards, you can't create a new one. Microsoft allows only one free account per person.

Use a valid credit card, not a prepaid or virtual one, for Azure sign-ups. The billing address on the card must match your account address.
Check that the information you entered (email, address, phone number) is correct and matches your bank records. Mismatches could cause verification issues.
Browser settings can sometimes cause problems with registration. Try clearing cookies, using a different browser, or going into incognito mode to see if that helps.
If you have any further queries, do let us know.
