No, of course not. Anyone can make a program that can create strings of 20 characters that could possibly be used as 3DS codes, but codes are only valid when purchased. The chances of it generating a code that's currently 'live' are billions to one, and that might even be an understatement.
That comes to a second point - the only people who say they have a working generator are trying to trick you somehow. Either they want you to download and install malware, or the generator will be archived or non-functioning somehow, and will ask you to complete surveys to get the password/authentication or whatever. These surveys are how the scammers make their money.

3DS games do not have friend codes, it is the friend code of the 3DS itself that you use, to be able to play multiplayer on a 3DS game.
The 3DS itself has a universal friend code that is used on all the 3DS games and applications the player uses. It means they only need to add a friend once, by adding their 3DS code, they can play multiplayer in any 3DS game that supports it. For regular DS games, it is the game itself that has its own code, so you'd register your friend's Soul Silver friend code on your own Soul Silver, etc, whether you play it in a 3DS or the older models. You could not though add someone's Soul Silver code to the 3DS friend list.
