Many people find they can't receive Binance verification codes after moving abroad for study or work, or after switching carriers. This is a common issue, and this article covers the specific solutions. If you don't have a Binance account yet, consider using a long-term stable phone number when you register on Binance.
Why Can't You Receive Codes After Changing Countries?
1. Phone Number Deactivated
Your original phone number may have been suspended or deactivated after moving abroad if international roaming wasn't enabled.
2. International SMS Blocked
Some overseas carriers block verification SMS messages from foreign sources.
3. Country Code Mismatch
Binance may send verification codes to a country code that doesn't match your current phone number's country.
Solutions
Method 1: Keep Your Original Number Active
If your original phone number hasn't been cancelled, the simplest approach is to keep it active:
- Enable international roaming (contact your original carrier)
- Use an eSIM-capable phone to keep both numbers simultaneously
- Have family at home help with top-ups to keep the number active
Method 2: Change Your Phone Number on Binance
If the original number is no longer usable, you'll need to update your bound phone number:
- Log into the Binance app (you must be able to log in through other means, like email + Google Authenticator)
- Go to "Security," then "Phone Verification"
- Select "Change Phone Number"
- Verify your identity using alternative methods (email code, Google Authenticator)
- Enter your new phone number with the correct country code
- Verify the new phone number
Prerequisite: You need at least one other working verification method (email or Google Authenticator).
Method 3: Contact Support When You Can't Log In
If you can't log in at all (phone unavailable, email issues too), you'll need Binance support for manual processing:
- Find the "Live Support" entry on the Binance login page
- Or send an email to Binance's support address
- You'll need to provide:
- Registration email
- ID document photos
- Selfie holding your ID
- Account information (such as recent transactions)
- Wait for support to review and process
Security Restrictions After Changing Phone Number
After changing your phone number, Binance applies temporary security restrictions:
- No withdrawals for 24-48 hours
- Some features may be temporarily limited
- All logged-in devices may need re-verification
These restrictions prevent malicious phone number changes for asset theft.
Preventive Measures
1. Bind Google Authenticator
Google Authenticator doesn't depend on a phone number and works regardless of country changes. This is the most important backup verification method.
2. Bind an Email
Ensure your bound email is stable and accessible (Gmail recommended), unaffected by phone number changes.
3. Enable All Three Verification Methods
Phone, email, and Google Authenticator — enable all three so any single failure has a backup.
4. Prepare Before Traveling Abroad
If you plan to go abroad:
- Confirm international roaming is enabled
- Confirm Google Authenticator is backed up
- Remember your email password
- Download the latest Binance app version
5. Register with a Stable Phone Number
Use a phone number you won't change frequently. If you switch numbers often, email registration is more reliable.
eSIM Solutions
If your phone supports eSIM, consider:
- Keep your original physical SIM card (maintain your home number)
- Use eSIM for the local carrier
- This way both numbers work simultaneously
Summary
The best solution for not receiving Binance codes after changing your phone number's country is to update your bound phone number in account security settings. To prevent this situation, always enable Google Authenticator as backup, and confirm all verification methods work before traveling abroad.
