How do I delete my Yahoo account permanently from my phone?

To cancel paid services and pay account balances, go to My Subscriptions in your Yahoo account. Sign in to the Yahoo account termination page using your username and password. Read the terms of cancellation for your account. Use the on-screen instructions to finish the process.

Enter your username on the Yahoo Delete My Account page and follow the instructions to deactivate your account.

If you want to prematurely terminate your Yahoo ID, you must remove the whole account. If you can wait four months, your Yahoo ID will be disabled after that time period has passed. You’ll lose access to your Flickr account and other stuff if you delete your Yahoo account.
