Suggestion needed: List building tool

[moz_fanboy]

I need a tool that has features like if i enter number in it then the missing information like email address and name ,etc are fetched online and this makes it a complete contact information. This can be really great to segment my emails or sms marketing efforts. I have seen this quite a while back but i cant figure it out just yet. Anybody know the name?

Hello Hardik,

I think you are referring to a tool/service like eGrabber:
