Common ProblemsWhen I try to add my phone number to my Battle.net account, I receive a text, but the code is invalid.
In the US, messages from Blizzard come from a 6 digit number - this is not the code itself, but the sender.
Please open the message and read the body of the message - it's easy to get confused if you read the preview.
Here is an example of a verification code being sent:
Body: "Your verification code is 484312 - Blizzard Entertainment"
