Changing phone numbers is quite common, but forgetting to update your linked number on Binance could affect your account's normal usage. This article teaches you how to change the phone number linked to your Binance account. Users without an account can register on Binance now, and download the Binance APP to proceed.

Scenario 1: Old Phone Number Still Works

If your old phone number is still in use, the process is straightforward:

  1. Log into your Binance account
  2. Go to [Profile] > [Security Settings]
  3. Find "Phone Verification" and click [Modify]
  4. Enter the verification code sent to your old phone number
  5. Complete additional security verifications such as Google Authenticator
  6. Enter your new phone number and verify it (you'll receive a verification SMS on the new number)
  7. Change complete

The entire process takes just a few minutes. Note that verification codes are typically valid for 5-10 minutes — if they expire, you'll need to request new ones. We recommend having both your old and new phones nearby before starting, with good signal and normal SMS reception.

Another common issue is verification code delays. If you haven't received the code after 2-3 minutes, try clicking "Resend." Some carriers may block SMS messages from overseas numbers — if you consistently can't receive codes, try switching to email verification instead.

Scenario 2: Old Phone Number Is Deactivated

If the old phone number is no longer in service, you'll need to go through identity verification:

  1. After logging into Binance, try to modify your phone number in Security Settings
  2. Select the "Verification Unavailable" option
  3. The system will guide you through identity verification
  4. Upload ID photos and a selfie (ensure photos are clear with good lighting)
  5. Provide account-related information to verify your identity (such as registration email, recent transaction records, etc.)
  6. Wait for approval, then link your new phone number

Review typically takes 1-3 business days. To speed up the process, make sure your ID photos are clear and complete, take your selfie in well-lit conditions, and ensure the ID is not obstructed or reflecting light. Providing additional supporting information (such as account registration date, deposit records, etc.) can also help expedite the review.

When You Can't Log In at All

If your old phone number prevents you from logging in entirely:

  1. Click "Security Verification Unavailable" on the login page
  2. Verify your identity through email verification
  3. Follow the prompts to submit identity documents
  4. Contact Binance online customer service to expedite the process

This situation may take longer to resolve since it involves advanced account security verification. We recommend submitting a ticket through Binance's official website online customer service with a detailed description of your situation. Include as much information as possible in the ticket: account registration email, account UID (if you remember it), ID document number used during registration, etc.

Handling Special Cases

Old phone number registered to a new Binance account by someone else: If the new user of your old phone number registered a Binance account with it, this won't affect your account security. The association between a phone number and an account is verification-based and doesn't automatically transfer. You'll still need to follow the procedures above to change your phone number.

Switching between domestic and overseas phone numbers: If you're switching from a domestic number to an overseas number (or vice versa), the process is the same — just select the correct country/region code when entering your new phone number.

Preventive Tips

  • Update your phone number on Binance before canceling the old number — this is the simplest approach
  • Keep your old phone number active for at least one month to ensure a safe transition period. Many carriers allow you to maintain the number for a period before deactivation
  • Enable multiple verification methods so that even if your phone number changes, other verifications still work. We recommend binding email verification and Google Authenticator simultaneously
  • Regularly update your personal contact information — don't wait until it's unusable to make changes
  • Record your Binance account security information (UID, registration email, etc.) in a safe place, in case you need to recover your account

With these preparations in place, changing your phone number won't significantly impact your Binance account usage.
