There's a silver lining, though. Friend codes are one way to add friends on the Switch, but not the only way. After the Switch's day-one software update, players have four ways of managing their friends list: search for local users, search for users you've played with, search with friend code and sent friend requests.
It's worth noting that the second option will suggest contacts from Nintendo's mobile games Miitomo and Super Mario Run, Nintendo Life says. The friends list is also capped at 300 users, according to a Japanese Nintendo support page detailing the update. As Polygon reminds us, this is a lot less than the 2,000 friend limit on PlayStation Network and the 1,000 max on Xbox Live.
This isn't the first time we've been told friend codes would go extinct: Ubisoft said back in 2011 that the feature was on its way out, but clearly, that never came to pass. Still, this update isn't all bad, since it also brings the eShop to the Switch in time for the March 3rd launch (although Virtual Console titles won't be available then). So congrats on adding core features to your console a day before the masses get their hands on it, we suppose.
