To add friends in MW2 or Warzone 2:

- Type in their Activision ID or Gamertag and hit “Send Request”
How to Add Friends Using Activision ID
To add a friend by using their Activision ID, boot up the game and open the Social Menu by pressing in the Right Analog Stick or hitting F2.
From there, select Add Friends, then type in their Activision ID and hit Send Request. The Activision ID must contain the player’s username, the hashtag, and the numbers that follow (if they have any).

The typical Activision ID will look like this: Playername#12345
Once your request is sent, the other player must manually accept it before they will appear in your friend list.

How Do I Find My Activision ID
In the MW2 & Warzone Social Menu, press in the Left Analog Stick or press the 3 key.
You will be able to see your Activision ID on the right side of the screen, and even copy it to clipboard using the button beside it.

You can also see your Activision ID by opening Settings (press Menu/Options and tab over to the gear), going to Account & Network, and selecting Activision Account.
Note: You may need to hit Show Details to reveal your Activision number that goes after your username when viewed in this manner. Not all Activision accounts have numbers as part of their ID.
How to Add Crossplay Friends
First, console users will want to open the Settings menu by pressing Menu/Options and scrolling over to the gear icon. Go to Account & Network and check that Crossplay is set to On.
Next up, head to the Social Menu by pressing in the Right Analog Stick or hitting F2.
Then select Add Friends.

You can add crossplay friends using their Activision ID as shown in the method above, but if you don’t know it, you can also select “Don’t Know Their Activision ID?“

Then, you can select from 3 options: Other PC, Online ID (PlayStation), or Gamertag (Xbox). Click the appropriate one and enter your friend’s ID on that platform, before hitting Send Request.

How to Add Friends on Same Console / Platform
Even when adding friends on the same console or PC platform that you’re active on, you can still use their Activision ID to send them a friend request.
However, if you prefer, after opening the Social menu and choosing Add Friend, you can then hit the button at the bottom of the screen to search your respective platform.
For me, I have the option to search my Steam friends, but Battle.net, Xbox, and PlayStation users will all be allowed to search their relevant friends lists from here. Simply select the correct user from your friend list and hit Add Friend to send them a quick-and-easy request.

How to Accept Friend Requests in MW2 & Warzone 2
To accept an incoming friend request, press Options/Menu, and tab across to the Notification bell icon (or simply click it).
From there, select the friend request you’d like to accept.

You can also accept friend requests from the Social menu, where they’ll appear in the requests section.
