But in my URL there is no specific names but only number like 700000FBR, so do they get it from the URL? My concern is if the URL completely indexed in the SEARCH INDEX?
Nameless parameters? Better give an example. Using, ahem, example.com. There shouldn't be any relationship between tracking a campaign and showing non-meaningful parameters in search. If the parameter does have meaning, keep it. That's the default anyway. Have a look in Google Webmaster Tools.
Matter of fact, your public URLs shouldn't have any visible parameters. It's just clutter. But that's a matter for a different thread.
