How to change your phone number on Binance? (Account update)

Accessing Account Security Settings

1. Log in to your Binance account using your current credentials via the official website or mobile application.

2. Navigate to the user profile icon located in the top-right corner of the interface.

3. Select “Security” from the dropdown menu to enter the account security dashboard.

4. Scroll down to locate the “Phone Number” section under the verification methods list.

5. Click the “Edit” button adjacent to the displayed phone number to initiate the update process.

Verification Requirements for Phone Update

1. Binance mandates two-factor authentication (2FA) to be enabled before modifying contact details—this includes Google Authenticator or SMS-based 2FA.

2. You must have access to the currently registered phone number to receive a one-time verification code.

3. If the old number is no longer accessible, users are required to submit identity documents through the “Account Recovery” portal.

4. The system may prompt additional confirmation steps such as email verification or biometric checks depending on account tier and jurisdiction.

5. Attempting to bypass verification triggers temporary account restrictions until manual review is completed by Binance support.

Entering New Contact Information

1. After passing initial verification, input the new country code and full mobile number in the designated fields.

2. Ensure the number format complies with international standards—no leading zeros, spaces, or special characters except the plus sign before the country code.

3. A six-digit SMS code will be sent instantly to the new number; entry must occur within three minutes.

4. Duplicate submissions or incorrect entries beyond five attempts will lock the update function for 24 hours.

5. Upon successful validation, the interface displays a green success message confirming the change has taken effect immediately.

Post-Update Security Implications

1. All future login attempts will require SMS codes sent exclusively to the updated number unless alternative 2FA methods are configured.

2. Withdrawal whitelists tied to the previous number become invalid and must be re-registered manually.

3. API key permissions remain unaffected, but newly generated keys default to the updated phone number for emergency revocation protocols.

4. Subscriptions to Binance announcements or market alerts automatically migrate to the new number without requiring re-subscription.

5. Any pending withdrawal requests initiated before the update retain their original verification path and do not inherit the new number’s authorization scope.

Frequently Asked Questions

Q1: Can I change my phone number if I lost access to both my old number and email?Yes—but only after completing the Account Recovery process, which involves submitting government-issued ID, a selfie holding the ID, and answering security questions tied to registration data.

Q2: Does changing my phone number affect my Binance Wallet address or deposit history?No. Wallet addresses, transaction records, and asset balances remain completely unchanged regardless of contact information updates.

Q3: Why does Binance block phone number changes during high-risk login sessions?This occurs when the system detects anomalies such as unfamiliar IP locations, rapid successive logins, or mismatched device fingerprints—measures designed to prevent unauthorized account takeovers.

Q4: Is it possible to register multiple phone numbers for one Binance account?No. Binance allows only one active phone number per account at any given time to maintain compliance with anti-money laundering regulations.
