I assume you have either Heart Gold or Soul Silver. These are the only Pokémon games that have the ability for your player to get 16 badges. Every other game has 8 badges. If you mean specifically how do you obtain badges, beat the gym leaders in the different towns. If you want a complete walkthrough of how to get every badge, just search "[game] walkthrough".
