Based on the error message "You're not eligible for an Azure free account"
could be the email address was used in the past for an Azure free account.
Same if the credit card was used for an Azure free account before.
It could be invalid address information, phone number or email address.
More details you will find here: You see the message 'You are not eligible for an Azure subscription'
To resolve this issue, double-check whether the following items are true:
- The information that you provided for your Azure account profile (including contact email address, street address, and telephone number) is correct.

In order to change the email address -

Select Update contact info to update the email address then select Save.
