To recover Yahoo Mail using a new phone number or Help 1–866–719–1004, first go to the Yahoo Sign-in Helper (login.yahoo.com/forgot). Enter your email address and follow the prompts. Since the old number is no longer available, Yahoo may offer alternative verification methods like your alternate email. If you regain access, immediately update your account settings with your new phone number for future recovery needs. Without access to a registered recovery method, it might not be possible to regain entry. Keeping your recovery information current is essential for smooth and secure account access.
