How to change phone number on Binance

If you’ve changed your SIM card, switched numbers, or simply want to update the contact details on your Binance account, you’ll be glad to know the process is usually straightforward. Your phone number is an important part of account security—used for verification codes and recovery—so it’s worth updating as soon as you can.

Below is a clear, step-by-step guide, plus the main pros and cons to consider before you make changes.

Before you start: what to know

Changing your phone number on Binance generally involves verifying your identity and confirming the new number. Depending on your region and account status, the exact screens you see may vary slightly, but the overall flow remains similar.

A few quick checks can save time:

Make sure you can receive SMS on the new number right away.
Confirm your current number is still active (if the process requires SMS verification).
Have access to your email as well, since some steps may use it for confirmation or recovery.
Avoid delays—some verification codes expire quickly.

Step-by-step guide (Binance app)

1) Open Binance and go to account settings

Launch the Binance app
Tap Profile (or the menu icon)
Go to Security (sometimes found under Account → Security)

2) Find “Phone number” or the option to update it

Look for an option such as:

Phone number
Phone
Security settings → Change phone number

Tap the relevant option to begin.

3) Enter your new phone number

You’ll typically be asked to:

Choose your country/region code
Enter the new phone number

Double-check for typos. A single wrong digit can force you to restart the verification step.

4) Verify using a code (SMS)

Binance will usually send a verification code to your new number (and in some cases also to your existing number).

Enter the code in the app
Confirm when the verification succeeds

5) Complete identity checks (if prompted)

For security reasons, Binance may ask you to verify your identity. This could include:

Confirmation of basic account information
Additional verification steps

If you already completed verification before, it may be faster—but don’t be surprised if Binance asks again when sensitive details change.

6) Confirm the update

Once verification is successful, you should see a confirmation that your phone number has been updated. Keep an eye on the screen—some versions show a “completed” message, while others return you to the security page showing the new number.

Step-by-step guide (Binance website)

If you prefer using a computer:

1) Log in to your Binance account

Go to the Binance website
Sign in using your usual credentials

2) Navigate to security settings

Open Profile or Account
Choose Security
Find Phone number or Change phone number

3) Enter the new number and confirm

Add your new phone number with the correct country code
Complete the SMS verification prompts

4) Finish any identity checks

If the system requests additional verification, follow the on-screen instructions until it completes.

5) Verify the final status

Return to your security settings and confirm the new phone number is displayed correctly.

Guide: common problems and how to fix them

“I can’t receive the SMS code”

This is one of the most common issues. Try:

Checking signal reception and mobile data
Turning airplane mode off/on
Making sure your new number can receive SMS (not blocked by carrier settings)
Waiting a minute and requesting a new code (if available)
Avoiding VPNs or network changes during verification (if it seems to affect delivery)

If you still can’t get the code, Binance support may ask you to verify your identity through a different method.

“My old number is no longer active”

Depending on the account setup, you may still be able to change it, but verification becomes more important. If you can’t receive codes on your old number:

Use the recovery flow provided by Binance (if available)
Be prepared for identity verification requirements
Ensure your email and other security methods are accessible

“The phone number is already in use”

Binance may block numbers used on other accounts. In that case:

Use a different number, or
If you believe the number belongs to your account, contact support for clarification

“Verification keeps failing”

If codes don’t work even when entered correctly:

Confirm you entered the correct digits
Don’t repeatedly submit codes too quickly (it can trigger rate limits)
Try again after a short pause

Pros and cons of updating your phone number

Pros

Improved account recovery: If you ever need to regain access, having the correct phone number can help.
Stronger security: Binance uses phone verification for sensitive actions, withdrawals (depending on settings), and login confirmations.
Less hassle with 2FA/verification codes: You won’t miss SMS codes because they’re going to an old number.
Better reliability for notifications: Transaction-related security steps are often tied to contact verification.

Cons

You may need extra verification: Changing phone numbers can trigger identity checks, which takes time.
Risk if you don’t have access to the new number: If you can’t receive the SMS, the change can’t be completed.
Account downtime for security actions: While the update is in progress, certain security-related steps may be temporarily affected.
Potential delays with support: If something goes wrong (especially without access to the old number), you may need to contact support.

Conclusion

Changing your phone number on Binance is an important security task and, in most cases, it can be done quickly through the app or website. The key is having access to the new number for SMS verification and completing any identity checks Binance requests.

If you run into issues—like missing SMS codes or an inactive old number—focus on verification steps and consider reaching out to Binance support when needed. Keeping your contact details up to date helps ensure your account stays protected and easier to recover.
