How to change your phone number on a Binance account in 2026?

Accessing Account Security Settings

1. Log in to your Binance account using your current credentials, including the existing phone number and password.

2. Navigate to the top-right corner of the dashboard and click on your profile icon to open the dropdown menu.

3. Select Security Center from the list to enter the dedicated security management interface.

4. Scroll down to the Phone Number section, where the currently registered number is displayed with a visible edit option.

5. Click the Edit button next to the phone number field to initiate the update process.

Verification Requirements for Change

1. Binance mandates two-factor authentication (2FA) verification before allowing any modification to contact details.

2. You must have access to your currently bound authenticator app or hardware security key to generate a valid time-based one-time password (TOTP).

3. If SMS-based 2FA is enabled, you will receive a verification code via the old number — this step confirms continued control over the prior device.

4. A secondary confirmation prompt appears if your account has recent login activity from unrecognized devices or locations.

5. The system may request identity verification documents if the account exhibits high-risk behavior patterns during the session.

Entering and Confirming the New Number

1. Input the full international format of your new mobile number, including country code without leading zeros or plus signs in some regional UI versions.

2. After entering the number, click Send Verification Code to trigger an SMS delivery to the new line.

3. Wait for the six-digit numeric code to arrive — delivery typically occurs within 30 seconds but may extend up to two minutes depending on carrier routing.

4. Paste the received code into the designated field and click Verify to complete the binding process.

5. Upon successful validation, the interface displays a green success banner confirming that the phone number has been updated.

Post-Update Security Checks

1. Immediately review all active sessions listed under Active Login Sessions and terminate any unfamiliar ones.

2. Re-scan the QR code in your authenticator app to re-link it with the updated account configuration, as some tokens may become invalid post-change.

3. Check email notifications for an automated alert confirming the phone number update — this serves as an audit trail.

4. Attempt a test withdrawal of a minimal amount to ensure all security layers respond correctly with the new contact method in place.

5. Update any third-party services linked to your Binance API keys that rely on phone-based alerts or recovery triggers.

Frequently Asked Questions

Q: Can I change my phone number if I no longer have access to the old one?A: Yes, but only after completing the Account Recovery Process, which includes submitting verified government-issued ID, proof of address, and answering pre-set security questions.

Q: Does changing the phone number affect my API key permissions?A: No, API key permissions remain unchanged unless manually revoked or regenerated; however, notification settings tied to SMS alerts will redirect to the new number.

Q: Why does Binance require TOTP even when SMS 2FA is disabled?A: Because phone number changes are classified as high-privilege actions, and TOTP provides stronger assurance of user identity than SMS alone.

Q: Is there a cooldown period between successive phone number updates?A: Yes, Binance enforces a 72-hour lockout window after each successful change to prevent rapid sequential modifications.
