Multiplayer is a feature in the that allows multiple players to interact with each other in various forms, the most common being visiting other players' towns.

It has always been possible across the to visit other towns, although only since  is it possible to play with another player at the same time, as well as visit towns through the Internet. At most three players can be invited by a host, although this is expanded in with seven invited players.

Friend Codes and Friends
A Friend Code is a 12-digit code that identifies any player.

In and, a Friend Code can be obtained for the first time by talking to Copper and saying "Friend Code!" This will connect to the Nintendo Wi-Fi Connection to assign the player a code. From onwards, Friend Codes and Friends are assigned on a system level.

Two players must add each other's Friend Code so that they can be friends. Prior to the introduction of Dodo Codes, two players must add each other as friends before they may visit each other. In, if two guests are on the same town but are not each other's friends, they may add each other in the Guest List at the bottom screen.

Best friends
Best friends can send messages to each other even when they're not in the same town. They only need to be online and have the best-friend message-exchange function turned on, which can be toggled anytime. When a player's best friend is online, they will receive a message from that person automatically saying "I am online!" A player can send a message to either only one Best Friend, or to all Best Friends online at the time.

In, two friends may become best friends if they both have the heart selected in each other's Guest List when together in a town, whether one of them is hosting or they're both in another friend's.

In, a player may send a Best Friend request to any friend in the Best Friends app regardless of where they are. The friend may either accept or reject this request.

Visiting other towns
A player can host their Friends by opening their town's gates and letting visitors in. This can be done by talking to Copper in and, Porter in , or Orville in. Likewise, a player can visit a friend by talking to these special characters and asking if there are any towns whose gates are opened.

The host can choose to end the session anytime via the Start or - menu. In addition, the host can close the town's gates anytime, ensuring that no more players can enter. If no other players are present when the gates are closed, the multiplayer session would also end.

Dodo codes
In, it is no longer required for players to be friends to visit each other. The player can request for a Dodo Code, a 5-character code that will expire once the multiplayer session ends. The Dodo Code allows the player to visit

Limitations
Hosts and visitors can do almost anything in multiplayer mode, although with some exceptions. The host cannot donate to Blathers or access some Town hall services when the multiplayer session is active. Visitors cannot use the lost and found nor the recycle box services.

Visiting other towns

Local Wireless multiplayer is only available in. After telling Copper "I wanna go out!", the player will be given the option between local and online play.

Up to four players can play in a single town via local wireless, and all players must have a copy of the game.

Dream Suite
Once the Dream Suite is built, the player can share a dream of their town for others to visit over the Internet. The dream acts as a saved state of the player's town at the time of sharing, and it must be updated manually.

Happy Home Showcase
The Happy Home Showcase allows players to meet and visit the houses of players that they have met over StreetPass.

In
Unlike previous games, up to eight players, including the host, can play on a single island, except for local co-op, where only up to four residents, including one leader, can play.

Multiple residents
In, this is the first game where up to eight players can live on one island, and they each have their own house. The first player to arrive on the island becomes the Resident Representative.

Local Co-Op
Local co-op multiplayer is a feature exclusive to, such that multiple players of the same island can play on the same console. A player can use the Call Resident app on their NookPhone to call up to three other residents on the island. This will start local co-op mode, where the initial player is assigned the role of "leader" while the others are known as "followers". The Call Resident app will only be unlocked once there is more than one player on the island, and this will be unlocked to all residents.

The leader is able to do several things similar to single player mode. They can access facilities such as the Nook terminal and their NookPhone, talk to other characters, and several others. They can also use Island Designer. Accessing the Call Resident app will allow the leader to view the followers' passports, end the session, change the leader, or close the game entirely. The leader is unable to access Orville's services.

Followers' actions are very limited. They cannot talk to villagers, use chat, enter or exit buildings, and access their inventory or Nookphone. They are able to access tools by pressing X, which will allow them to cycle through their tools but not other handheld items such as the and. Holding a non-tool handheld item as a leader and becoming a follower will cause the player to unequip it. They can use wands, but pressing A will toggle between their default outfit and a random outfit they have. Followers can use reactions but only the eight that they registered as favorites. Any items picked up or caught by a follower will be sent to the recycle box to be picked up later by anyone. A follower who digs something up or catches a critter will "exclaim" the name of that item in a speech bubble.

The leader and followers can move at the same time, but followers are unable to move whenever the leader has certain apps on their NookPhone open, or when they are accessing the chat keyboard or other facilities. Followers who move too far away from the leader will be teleported back near to them.

The leader can be switched by shaking the Joy-Con or Pro Controller, and a follower must press A while standing up to become a leader.

When the leader ends the session, they will be able to play on their own profile, even if they aren't the same player who started local co-op.

Friends
Friends from the player's Nintendo Switch Friends List who also have played will appear in the player's in-game Friends List. Like in previous games, friends can visit each other's islands over the Internet and send each other letters. A player must at least visit their friend's island or have their friend come to that player's island in order to send letters, they can also mark each other as best friends if conditions have been met and can send messages via the Best Friends app on NookPhone. This also marks the first game where a player's friend cannot modify the island with a Shovel or Axe unless they are registered as Best Friend.

Visiting other islands
The player can go to the Airport and talk to Orville to visit other player's towns, open their gate for other players to visit, or receive a Dodo Code.

Locally
All players must own a copy of the game. Additionally, the host does not need to mark them as Best Friend in order to modify the island.

Online
Players can visit friends' islands over the Internet, or they can enter a one-time use Dodo Code to visit the island of someone not on their Friends List, including dreams. All methods require a paid Nintendo Switch Online membership.
