Get my friend code / Obtener mi código de amigo

[odd crag]

In the WiiU menu, I go to the Friend List, choose my Mii, but my friend code is not displayed. What should I do to see/get my friend code?
I attach a screenshot where I only edited so that my NNID does not appear (although I use Pretendo Network)
Thank you.
En el menú de WiiU, voy a la Lista de Amigos, elijo mi Mii, pero no se muestra mi código de amigo. ¿Qué debo hacer para ver/obtener mi código de amigo?
Adjunto una captura donde solo edité que no salga mi NNID (aunque uso Pretendo Network)
Gracias.

There is no Friend Code on Wii U

you share the Pretendo Network ID to add people

[hushed otter]

The "friend code" u are looking for is the code that u deleted in the image

Oh, okay. Thanks. I didn't know that. So I add people with a 12-digit numeric code and they add me with some kind of username?

No

You give your Pretendo Network ID you censored

there is no code

The ID is used to add friends

Ok, my doubt comes because the rest provide friend codes in the format 1234 5678 9012, instead what I deleted from the capture is a username.

3DS uses friend codes

Wii U uses that username you just censored

Ok, fine. Sorry for my ignorance. I was never much of an online gamer, but with the resurgence of services thanks to Pretendo, I wanted to give them my support. (Plus I don't have any friends!)
I'll post a screenshot with my ID soon.
Thanks!

It's okay, have fun on Pretendo!

Can I close this?
