How to Change Your Blizzard Phone Number on Battle.net

To change your Blizzard phone number, sign in to your Battle.net Account Details page, scroll to Phone Number and click Update. Blizzard then asks you to confirm it’s you with an Authenticator code, an SMS code or an email code, so you don’t need the old phone if you can use one of the other two.

This guide covers the steps, what to do if you’ve lost the old number, and the rules the new number has to meet.

How to change your Blizzard phone number

Blizzard’s steps:

1. Go to your Account Details page and sign in.
2. Scroll down to Phone Number.
3. Click Update to change your number, or Remove to unlink it.
4. Verify your identity with an Authenticator code (from the Battle.net Authenticator app), an SMS code (if SMS Protect is active) or an email code sent to your registered email.
5. Enter the new number.

Blizzard adds one tip: “Make sure the new number can receive SMS messages for security features and game requirements”.

If you lost the old number

You don’t need it if you can confirm with the Authenticator or your email in step 4. If you can’t log in at all, Blizzard says: “Use the Account Recovery Tool to regain access first, then update or remove your number.” If you linked an external account, such as Xbox, PlayStation, Steam or Google, you can log in with that instead.

Still stuck? Contact Blizzard’s Customer Support, but note that “Customer Support are unable to add a number directly to an account.”

Lost the phone but kept the number? Nothing changes. Blizzard says phone notifications keep working “since it’s associated with your phone number rather than the device itself.”

Rules for the new number

• One account per number. “A phone number can only be added to a single Battle.net Account. Customer Support cannot bypass this limitation.” If the number is on another of your accounts, remove it there first.
• Same country as your account. The country code is filled in from your registered country, and the field “can’t be edited”. If you’ve moved, update your country first.
• No VoIP. Battle.net “supports mobile plans and prepaid numbers but does not support Voice Over Internet Protocol (VOIP) numbers.”
• Don’t request codes too fast. Too many SMS requests can get you blocked for a while; Blizzard asks you to “wait 24 hours before attempting to add the phone again”.

Moving your number to a different Battle.net account has a limit too: it “will not allow you to create a second free account for the same game on your new Battle.net Account.”

Removing a number can lock you out of games

Blizzard warns: “Some games require an SMS number to play. Removing your number may prevent access to those games until you add a new one.” Overwatch is one example for new accounts; see who needs a phone number for Overwatch. So update the number rather than removing it, unless the next one is ready.

Using a second number instead of your own

If you’d rather not put your personal number on Battle.net, a non-VoIP number from PVADeals is a real mobile line from a carrier, so Battle.net sees an ordinary mobile number.

1. Create a free PVADeals account and add credits: crypto from $3, or a card through Stripe from $5.
2. Choose Blizzard from the list of websites in the country on your Battle.net account: the United States or the United Kingdom. If it isn’t listed for your country, rent an All services number instead, which works on any website.
3. Rent long-term (3, 7, 14 or 30 days) and turn on auto-renew. Blizzard says a phone number “can also help you recover access to your account”, so a 20-minute number is the wrong tool here. See the prices below.
4. Click Update on Battle.net, confirm with your current method, enter the new number and type in the code from your PVADeals dashboard. PVADeals numbers receive SMS only.

Set up the Battle.net Authenticator too, so you can confirm future changes without SMS. If an eligible PVADeals number receives no SMS during the rental, its cost comes back to your balance automatically as store credit.
