To change your phone number on Twitch, log in and go directly to twitch.tv/settings/security. This is the only documented path for updating your number, whether you have a new phone or need to recover access to two-factor authentication (2FA) after losing your old device.
Go to your Twitch security settings
After logging into your Twitch account on the web, navigate to twitch.tv/settings/security. This is the exact page where your phone number is managed. If you have 2FA enabled, you may need to verify your identity through a code sent to your current phone number before accessing settings.
Update your phone number under Contact
On the security settings page, locate the Contact section. Next to Phone number, click the pencil icon. Choose your country code from the dropdown menu, enter your new phone number, and click Save. This is the only documented control for updating your number on Twitch.
Confirm your new phone number
Twitch will send a verification code via SMS to the new number you entered. The verification code sent by SMS is 7 digits. Enter this code to confirm the change. The confirmation step is required to activate the new number on your account.
Change your 2FA phone number without the old one
You can change your 2FA phone number without access to the old phone number, but you must still have access to your Twitch account. The 2FA setup path is Settings > Security and Privacy > Set up Two-Factor Authentication > Enable 2FA. If you no longer have access to the old phone number tied to two-factor authentication, you cannot change it directly in Twitch settings. Instead, you must contact Authy using their phone change form, as documented by Twitch. You still need access to your Twitch account to complete this process. This is the only supported method for updating a 2FA phone number when the old number is unavailable.
Frequently Asked Questions
Can I use a VoIP number for Twitch verification?
Twitch does not recommend using a VoIP number for 2FA phone entry. While the platform may accept VoIP numbers for general verification, using one for two-factor authentication is not advised and may cause issues receiving SMS codes.
Will changing my phone number affect my account settings or subscriptions?
Changing your phone number does not affect your account settings, followers, subscriptions, or any other Twitch features. Only the contact and security information linked to your phone number is updated.
What should I do if I encounter issues while updating my phone number on Twitch?
If you experience problems, first confirm you are using the exact web path twitch.tv/settings/security and that your new number is correctly entered with the right country code.
Why does Twitch require SMS verification when updating my phone number?
The SMS verification step ensures that only the account owner can authorize the change. This prevents unauthorized updates to your contact information and helps maintain account security.
Does updating phone number on apps like Twitch affect my other accounts?
Updating your phone number on Twitch only affects your Twitch account. It does not change the phone number linked to any other service, platform, or app you use. Each account must be updated separately.
