Phone number "invalid" issue being a complete run around

I have been trying to connect my phone for the last couple days to my Battlenet account so I would have 3 factor authentication but been running into the “invalid phone number” issue constantly.

I have already tried to go through blizz live support and ticket support to have them both say “You must speak with your provider to make sure your number is not a pre paid number and or used as a Voip number and make sure its in the right country listing”

Which all of that is correct, Spoke with my provider who was absolutely bewildered by this issue and confirmed my number is normal month to month service and has not been used as a VOIP number in the past.

This started with me wanting to try the new CoD free BR which lead me to want to make sure I have 3 factor authentication so my account was secure.

when contacting with the support here my only other option is “buy the game” according too the gamemaster I spoke with (which I am not angry with him specifically, (he’s a dude working in the confines of a broken support system) but that is some out right underhanded slimy business practice thats going on.

I refuse to buy a 80 (CAD) game just so I can play what should be free to me like everyone else, not only that I have already wasted 2 hours and money off my internet bill downloading this gigantic program.

what do I do honestly? No other launcher platform has ever had this issue with me, not steam, not origin, not even bloody Uplay. I had kept getting told that “we can’t force a number on there as it is not under our control”, So you’re saying you cannot control your OWN god damn info section of your users if something like being hacked where to happen? Thats a You guys issue, none of it is anyone elses.

Fix your garbage support system Blizz and stop giving us the run around and trying to pass the buck.

I can provide screens of my provider being bewildered if needed. (poor happy the support worker at my provider you did try bud).


I’m having the exact same problem, it says my number is invalid, after waiting for so many hours for the game to download now I have to deal this.

I have a similar issue, my phone number did work recently for the past year, I decided to attach it to my other account to try and play CoD as it required it. The number decided to say “invalid phone number” constantly, which is weird as it was attached to my account for 12+ months, and now wont attach to my first account.
I was also told to check with my phone provider and see what the issue is with them, to no avail, everything seemed normal, I even went on a few other gaming sites, discord, twitch and Authy, to set up 2FA with the same phone number and it worked. I am receiving the short code messages to be able to log into those accounts. This could be an issue with the provider that blizzard decided to use for this system (as it isn’t even there own system) , I do believe it is TeleSign. as replying to the old blizzard 2FA message numbers i used to get says this company.

I had this issue aswell and got an answer if you have a phone provider such as cricket boost or the other “prepaid” phone companies they do not accept them as valid phone numbers.
