How can you find out someone's identity from their Yahoo ID?

Answer 1

you can't

Improved: You can find out who someone is if you enter the screen name they are using into Google. If they've used that screen name before on different websites, it will pull up. If they've posted their information on said websites (like their name and location) you could go from there.

For internet security purposes, always use a different screen name for every website that you must create one for.

Answer 2

They would have to tell you who they are.

Just ask the person
