Once you've established your friend code, you can start adding friends. There are two ways to do this on the Nintendo 3DS, either without offline (locally) or online.
Here's how to add friends locally:
1. Select the friend list icon on the HOME menu.
2. Tap 'Register Friend' at the top of the screen.
3. Tap 'Local'.
4. Tap on your friend's card when it appears on-screen to start the connection.
5. Once the friend information is exchanged, tap 'Close' to return to the HOME Menu.
If you'd like to add a friend on the internet, you do it like this:
1. Select the friend list icon on the HOME Menu.
2. Tap 'Register Friend' at the top of the screen.
3. Tap 'Internet'.
4. Enter the friend code of the person you want to register, and tap OK.
5. If you are not yet registered on the friend's system, you'll have to enter a temporary name for them, and then tap OK.
6. When the person registers you in return, the status will change and you will become fully registered friends. That person's name and Mii will then be displayed.
7. Tap 'Close' to return to the HOME Menu.
