How to Change Your Linked Phone Number on Binance

After changing your phone number, you must remember to change the linked phone number on Binance as well. Otherwise, you won't be able to receive verification codes when doing security verification in the future, and in severe cases, it may cause your account to become unusable. This article teaches you how to change your linked phone number on the Binance official website. You can also operate on the Binance official APP with similar steps. For Apple phone APP installation methods, see the iOS installation guide.

Why You Need to Change Your Linked Phone Number Promptly

Failing to update Binance promptly after changing your phone number will bring the following problems:

Cannot perform security verification: Many operations (login, withdrawal, modifying settings) require a phone SMS verification code.
Cannot recover password: If you forget your password and use your phone number to reset it, the old number cannot receive the verification code.
Old number used by someone else: Operators will reassign canceled phone numbers to others. If the new owner uses your old number to try logging in or recovering the password, it will create security risks.
Affects trading: Certain trade confirmations require phone verification; if the phone number is wrong, you cannot operate.

So, as soon as you change your phone number, you should go to Binance to change the binding immediately.

Scenario 1: The Old Phone Number is Still Available

If your old phone number is still in use (can still receive SMS), the changing process is very simple.

Operation Steps

Step 1: Enter security settings

Web version:

Log into Binance.
Click the avatar in the top right corner.
Select "Security".

APP version:

Open the APP and log in.
Click the avatar in the top left corner.
Select "Security".

Step 2: Find the phone verification option

In the security settings page, find the "Phone Number Verification" or "SMS Verification" option. You will see the currently bound phone number (some digits will be hidden). Click the "Change" button next to it.

Step 3: Verify identity

The system will require you to perform security verification:

Send a verification code to the old phone number → enter the verification code received by the old phone.
If email verification is enabled → enter the verification code received by email.
If Google Authenticator is enabled → enter the current Google verification code.

This is multi-factor verification, and you may need to enter multiple verification codes simultaneously.

Step 4: Enter the new phone number

After passing the verification, the system will ask you to enter the new phone number. Select the correct country code, and then enter the new phone number.

Step 5: Verify the new phone number

The system sends a verification code to your new phone number; enter the received verification code to confirm.

Step 6: Change completed

After passing the verification, the phone number is successfully changed. All future SMS verification codes will be sent to the new phone number.

Scenario 2: The Old Phone Number is No Longer Available

This situation is trickier because Binance needs to confirm that you are the one operating, and if the old phone number cannot receive the verification code, conventional verification won't work. But there are still ways to handle it.

Method 1: Substitute with Other Verification Methods

If your account is bound to both an email and Google Authenticator, you can bypass phone verification in some cases:

Enter security settings → Change phone number.
When the system asks for the old phone verification code, check if there is an "Unavailable" or "Security verification unavailable" option.
After clicking, the system may ask you to substitute it with an email verification code + Google verification code.
After completing the substitute verification, enter the new phone number and verify it.

Method 2: Process via Online Customer Service

If Method 1 is not feasible:

Log into your Binance account.
Go to the Help Center.
Select "Online Support".
Explain that you need to change your phone number and the old number is no longer available.
Customer service will guide you to submit identity verification materials.

Method 3: Submit a Ticket

Submit a security-related ticket in the Help Center.
Select the issue type as "Change phone number".
Describe the situation in detail.
Provide the following materials as required:
- Photos of the ID document used for KYC verification.
- A selfie holding the document.
- Email information used at account registration.
- Screenshots of recent transaction records (to prove you are the account owner).
Submit and wait for review.

Manual Processing Time

Changing the binding via customer service or a ticket usually takes:

Fast: 1-3 working days.
Slow: 5-7 working days.
Longer if supplementary materials are needed.

So, to emphasize again — you must first change the binding on Binance before changing your phone number.

Precautions After Changing Your Phone Number

Temporary Security Restrictions

Similar to resetting a password, changing your phone number may trigger some temporary security restrictions:

Withdrawals may be suspended for 24 hours.
Certain sensitive operations may require extra verification.

These restrictions will automatically be lifted after a certain period.

Check Other Associated Services

After changing your phone number, besides Binance, also check other important services registered with the old phone number (banks, other exchanges, social media, etc.) to ensure they are all updated.

Confirm the New Phone Number Can Receive Verification Codes

After the change is completed, it is recommended to immediately perform an operation that requires a phone verification code (like logging out and logging back in) to confirm that the new phone number can receive Binance's verification codes normally.

Preventive Measures Against Losing Your Phone Number

Bind an Email Simultaneously

Ensure your Binance account is bound to an email at the same time. This way, even if something goes wrong with your phone number, you still have the email as a backup verification method.

Enable Google Authenticator

Google Authenticator does not rely on a phone number, so even if you change your number, it won't be affected. It is strongly recommended to enable it.

Record Account Information

Record your Binance account-related information in a safe place:

Registered email.
Bound phone number.
Google Authenticator backup key.
Registration time and other information.

This information will be used when you need to recover your account or contact customer service.

Handle in Advance

If you know you are about to change your phone number (e.g., planning to port your number to a new carrier or cancel the old number), complete the change operation on Binance in advance.

Handling Special Situations

Phone Number Reclaimed by the Operator

If your old phone number was reclaimed by the operator due to unpaid bills, etc., and has been assigned to someone else:

Contact Binance customer service immediately to explain the situation.
Do not wait until the new owner tries to log into your account to act.
Provide identity proof materials to change the binding.

Changed to a Local Phone Number Overseas

If you use a local phone number after going abroad:

Binance supports binding phone numbers from different countries.
When changing, select the country code corresponding to the new phone number.
Note that there may be delays in receiving international SMS.

The Same New Phone Number Was Previously Bound to Another Binance Account

One phone number can only be bound to one Binance account. If your new phone number was previously bound by someone else (although the probability is very small), you need to contact Binance customer service to resolve this conflict.

Frequently Asked Questions

How long does it take to change the linked phone number?

If the old phone number is still available, the entire change process only takes 5-10 minutes. If the old phone number is unavailable and requires a manual process, it usually takes 1-7 working days.

Will changing my phone number affect my assets and trading?

Changing the phone number itself will not affect your assets. However, there may be a 24-hour withdrawal restriction after the change, which is a security protection mechanism. Other functions like spot trading are usually not affected.

Can I bind a virtual number or a Google Voice number?

Not recommended. The stability of virtual numbers is not good enough, which may affect the reception of verification codes. Moreover, if the virtual number service has issues, you may not be able to perform security verification. It is recommended to use a phone number with a physical SIM card.

Do I need to redo KYC after changing my phone number?

No. Changing your phone number and KYC verification are independent; changing your phone number does not affect your real-name verification status.

I haven't bound a phone number, can I just add one?

Yes. If you registered with an email and haven't bound a phone number yet, find "Phone Number Verification" in the security settings, click "Enable" or "Bind", and follow the prompts. This process is simpler than changing a number because you don't need to verify an old phone number.
