Can the police pull me over for driving on the suspended/revoked if they know I have no license and can prove that by someone giving the police a tip?

I have a revoked driver's license from a different state. I also have several bench warrants for me for driving on the suspended/revoked list in 2 different states. I currently have no license still. Do they have to witness me doing a driving offense or can they just stop me on a tip from the tip department in the police department that has been verified by police?
