The PHONE NUMBER REQUIRED error in Overwatch 2 is triggered by Blizzard's SMS Protect system, which requires a valid mobile phone number linked to your Battle.net account before you can play. This security feature was introduced to reduce cheating and smurfing, but it can block legitimate players who use prepaid phones, VoIP numbers, or haven't yet added a number to their account. Fortunately, resolving this error is typically straightforward and can be done entirely through your Battle.net account settings online.

How to Fix Error Code PHONE NUMBER REQUIRED

  1. Log In to Your Battle.net Account Online

  2. Navigate to Account Security Settings

  3. Add a Valid Mobile Phone Number

    Do not use a VoIP, prepaid burner, or internet-based phone number — Blizzard actively rejects these and your account will remain blocked. You must use a real postpaid carrier mobile number.

  4. If Your Prepaid Number Was Rejected, Switch to a Postpaid Line

    Never share your Battle.net login credentials with anyone else. If using a friend or family member's number, only ask them to receive the one-time SMS verification code — you do not need to give them your password.

  5. Check If Your Existing Number Is Already Linked to Another Account

  6. Launch Overwatch 2 and Test the Fix

  7. Contact Blizzard Support If the Error Persists

When to Call a Professional

This error does not require professional repair. However, if you have added a valid postpaid phone number and the error persists even after restarting the Battle.net client and the game, you should contact Blizzard Customer Support at support.battle.net. A Blizzard support agent is the appropriate 'professional' here — they can investigate account-level issues, verify that your number was accepted on their backend, and escalate the case if there is a system error or account flag preventing you from playing.

Frequently Asked Questions

Can I use a Google Voice or VoIP number for Overwatch 2 SMS Protect?
No. Blizzard explicitly blocks VoIP numbers, including Google Voice, Skype numbers, TextNow, and similar internet-based phone services. You must use a real postpaid mobile phone number from a legitimate carrier. If you try to use a VoIP number, your verification will fail and the PHONE NUMBER REQUIRED error will persist.
Can I use a prepaid phone number for Overwatch 2?
In most cases, no. Blizzard's SMS Protect system rejects prepaid or pay-as-you-go mobile numbers in many countries. You will need a postpaid (contract) mobile number to pass verification. Some prepaid numbers from major carriers may work in certain regions, but this is inconsistent. If yours is rejected, you will need to use a postpaid number.
Can the same phone number be used on multiple Overwatch 2 accounts?
Blizzard restricts how many Battle.net accounts can share the same phone number. Generally, one phone number can only be associated with a very limited number of accounts. If your number is already attached to another Battle.net account you own (such as an old account), you must remove it from that account before adding it to a new one.
Is the Overwatch 2 phone number requirement permanent?
Blizzard introduced SMS Protect as an ongoing requirement to help combat cheating and account abuse. As of now, there is no indication that Blizzard plans to remove this requirement for free-to-play accounts. Once you have verified your number, you will not need to re-verify unless you switch accounts or remove the number from your account settings.
What if I do not have a phone number to use for Overwatch 2?
If you genuinely do not have access to a valid postpaid mobile phone number, your options are: ask a trusted friend or family member to use their number for the one-time verification, purchase an inexpensive postpaid SIM card from a local carrier, or contact Blizzard Support at support.battle.net to explain your situation. Blizzard support can sometimes provide manual account exceptions in special circumstances.
