This Phone Number is Already in Use for Another Account

A phone number can only be added to a single Battle.net Account. Customer Support cannot bypass this limitation.

If you added your phone number to another Battle.net Account, log in to that account's Account Details page to remove the number.

If you are not sure what account your number is linked to, you can you can use the Battle.net Recovery service to be texted the email of the account and regain access. If the email is not yours, or you cannot regain access using the recovery service, please contact us with a phone bill showing your name and phone number.

Games Requiring a Phone Number

Some games such as Warzone 2.0, Call of Duty: Modern Warfare II, and Call of Duty: Modern Warfare III, require that you add a phone number before you can play, and you cannot use the same number to create two accounts for the same game. Customer Support cannot help with unlinking a phone number from a game account.

If you used your number to create a free game account such as Overwatch 2 on your first Battle.net Account, you can move your phone number to a new Battle.net Account, but this will not allow you to create a second free account for the same game on your new Battle.net Account; for that you must add a different, unused phone number instead.
