How to Change Your Binance Phone Number

Why Change Your Phone Number

Changing your bound phone number is a fairly common need, typically arising in these scenarios:

You got a new phone number
Your old number has been deactivated or canceled
Security concerns require changing your verification phone number
You moved to another country and are using a new phone number

Case 1: Old Phone Number Can Still Receive SMS

If your old phone number can still receive text messages, the change process is relatively simple.

On the Binance APP

Open the Binance APP
Tap the profile icon in the top left to enter your profile
Select "Security" or "Security Center"
Find the "Phone Verification" option
Tap "Change" or "Modify"
The system sends a verification code to the old number — enter it
Enter the new phone number
The system sends a verification code to the new number — enter it
Complete Google Authenticator verification (if enabled)
Change successful

On the Binance Website

Log into the Binance website
Click the profile icon in the top right > "Security"
Click "Change" in the "Phone Verification" section
Follow prompts to complete old phone number verification
Enter the new phone number and verify
Complete other security verifications
Change successful

Important Notes

Withdrawals will be prohibited for 24 hours after changing your phone number — this is a security measure
The new phone number cannot be one already bound to another Binance account
Ensure the new phone number can receive SMS normally

Case 2: Old Phone Number Cannot Receive SMS

If the old phone number is deactivated, canceled, or otherwise unusable, you'll need to go through identity verification.

Steps

Open the Binance APP or website
Go to Security Settings > Phone Verification > Change
On the page requesting the old phone verification code, select "Can't get verification code" or "Phone unavailable"
The system will guide you to the identity verification process

Security Tips for Phone Number Changes

1. Choose a Secure New Phone Number

Use a phone number registered under your own name
Avoid virtual or temporary numbers
Ensure the number will be used long-term and won't be easily canceled

2. Don't Rely Solely on Phone Verification

Phone numbers are relatively vulnerable to social engineering attacks (such as SIM swap attacks). It's recommended to also enable:

Google Authenticator
Email verification
This way, even if the phone number is compromised, other verification methods keep your account secure

3. Check Security Settings After the Change

After changing your phone number, review these security settings:

Google Authenticator is working properly
Email verification is functional
Anti-phishing code is correct
Withdrawal whitelist is intact
Check login history for anomalies

4. Watch for Scam Risks

Binance support will never proactively contact you asking to change your phone number
Don't perform phone changes through unofficial channels
When receiving emails about "needing to change your phone number," first verify it contains your anti-phishing code

Special Situations

International Number Change

If you moved from one country to another and need to change from an old country number to a new one:

The process is the same as a regular change
Select the correct country code
Ensure the new number can receive international SMS

Phone Number Reassigned to Someone Else

If your carrier reassigned your old phone number to someone else while it's still linked to your Binance account:

Contact Binance support immediately to change the binding
Provide identity proof materials
Also recommended to change your password and review account security

FAQs

Q: How long does it take to change a phone number? A: With the old phone number available, it takes just a few minutes. Without the old number, review takes 1-7 business days.

Q: Will changing my phone number affect Google Authenticator? A: No. Phone number changes and Google Authenticator are independent security settings that don't affect each other.

Q: Can I trade normally while changing my phone number? A: Yes, trading continues normally, but withdrawals may be restricted for 24 hours.

Q: Does the new phone number need to be registered under the same name as the KYC verification? A: It's recommended. While Binance may not strictly require the phone number's registered name to match the account name, using your own phone number is better for future security verifications.
