Open Friends > Add Friends and search the player's exact, case-sensitive COD Mobile username. Send the request from the matching profile, then have the other player accept it under Requests. If search fails, check spelling and capitalization, try Recent Teammates, and verify neither player is blocked or at the 100-friend limit.
Ask the other player to open their COD Mobile profile and copy the displayed public username exactly, including capitalization, spaces, symbols, and any numbers. Do not use a PlayerID, UID, PrivacyID, password, or verification code.
2
Open Add Friends
From the lobby, tap the two-person Friends icon near the upper-right corner, then open Add Friends.
3
Search and send the request
Enter the exact case-sensitive username, run the search, and compare the returned name and avatar. Tap the add-friend control on the correct profile once.
4
Accept the incoming request
On the other device, open Friends > Requests and accept the pending invitation. The task is complete when both players appear in each other's Friends list and can send a lobby invitation.
5
Try Recent Teammates when search fails
If you recently completed a match together, open Friends > Recent Teammates, locate the player, and send the request there. This avoids mistakes with uncommon symbols in a username.
6
Clear list and account conflicts
If the request still cannot be sent or accepted, confirm both players use the current app version, remove an old friend if either list has reached 100, and check both blocked-player lists. Then repeat one request rather than sending several.
If it does not work
If search returns no player, re-copy the public username and preserve its exact capitalization and symbols; do not substitute PlayerID, UID, or PrivacyID.
If the request was sent but the player does not appear, have the recipient check Friends > Requests and confirm neither account blocked the other.
If the add control is unavailable, reduce a full 100-player Friends list and make sure both devices have the same current COD Mobile version.

Activision's current help and competitive-play instructions use the public username, note that it is case-sensitive, and place incoming requests under Friends > Requests.
