What the UID is
The UID is the number Call of Duty Mobile uses for your account. It is separate from your in-game name, which you can change and which other players can copy.
The order form also asks for your login method: Facebook, Google, Apple, Activision or guest. That is not a request for the login itself — it only tells the seller which kind of account to look for.
Where to find it
-
1
Open COD Mobile and go to the lobby
Make sure you are on the account you want the CP on — many players have both a guest and a linked account.
-
2
Open your profile
Tap your name or avatar in the lobby to open the profile card.
-
3
Find the UID near your name
It is shown as a number with your name, usually with a copy option. If it is not on the profile card in your version, the account or settings screen shows it too.
-
4
Note the login method too
Whichever account you signed in with is what the order form wants.
A wrong UID delivers your CP to a stranger, and delivered top-ups cannot be reversed or refunded. Copy the number from the game rather than typing it out.
Mistakes people actually make
- Copying the UID from the guest account while playing on the linked one, or the other way round.
- Sending the in-game name instead of the UID.
- Picking the wrong login method on the form because two accounts are linked on the same phone.
- Buying a console or PC Call of Duty product and giving a Mobile UID.
Check it before you pay
-
1
Confirm which account you are on
Check the name in the lobby matches the account you mean to top up.
-
2
Paste the UID
Then read it back against the profile screen.
-
3
Match the login method
Pick the one you actually sign in with, not the one you think you set up years ago.
Common questions
Why does the login method matter if you have my UID?
It helps the seller confirm they are looking at the right account before sending. It gives them no access to it.
My account is a guest account. Is that a problem?
Some sellers handle guest accounts slower or not at all, because they are harder to verify. Linking the account to Facebook or Google first also protects the CP you are about to buy.
Should I ever send a code from my email or SMS?
No. Nothing about a normal top-up needs it. A request like that is an attempt to take the account.
