Why +86 Phone Numbers May Not Receive Binance Verification Codes
Not receiving SMS verification codes when registering for Binance with a mainland China +86 phone number is a problem that troubles many users. To understand this issue, you need to first understand the SMS verification code delivery mechanism.
As an overseas platform, Binance needs to send SMS verification codes to mainland China phone numbers through international SMS channels. Problems can occur at multiple points in this process:
Carrier blocking. China's three major carriers (China Mobile, China Unicom, China Telecom) have filtering mechanisms for international SMS. Some international messages may be classified as marketing or spam by the carrier and blocked, never reaching your phone.
Phone security software blocking. If your phone has security apps like 360 or Tencent Phone Manager installed, these may flag SMS from unknown numbers as spam and automatically block them. Verification codes can sometimes be caught in this net.
SMS channel congestion. During peak registration periods, Binance's SMS delivery channels may become congested, causing verification code delivery delays. In these cases, the code isn't missing—just late.
Phone number status issues. If your number was newly activated (less than a month), recently ported between carriers, or is a virtual operator number (beginning with 170, 171), you may experience difficulties receiving international SMS.
Network environment effects. Some users report that when using certain network tools, phone signal may be affected, which in turn affects SMS reception.
Immediate Solutions to Try
If you're registering for Binance but can't receive verification codes, try these methods one by one:
Method 1: Wait a bit. Sometimes the verification code is just delayed. After tapping send, wait patiently for 3-5 minutes. Don't repeatedly tap "Resend" during this time—frequent requests may actually trigger system rate limits.
Method 2: Check SMS blocking. Open your phone's messaging app and look for a "Blocked Messages" or "Spam" folder. Some phone brands (like Xiaomi and Huawei) automatically sort unknown number messages into spam. If you have third-party security software installed, check its blocking logs too.
Method 3: Resend the verification code. Wait at least 60 seconds (most platforms have a resend cooldown), then tap "Resend." Sometimes the second attempt routes through a different SMS channel and may succeed.
Method 4: Use voice verification. Some Binance versions support voice verification. If SMS codes aren't arriving, check if the page has a "Switch to Voice Verification" or "Voice Verification" option. Voice verification calls your phone and a robotic voice reads out the verification code digits.
Method 5: Switch to email registration. If SMS codes simply won't arrive, the simplest alternative is to register with email instead. Email verification code delivery rates are typically much higher than SMS. After registration, you can still link your phone number in account security settings.
Solutions for Carrier Blocking
If you suspect the carrier is blocking messages, try these approaches:
Call your carrier's customer service. China Mobile 10086, China Unicom 10010, China Telecom 10000. Tell them you're not receiving SMS verification codes from an overseas platform and ask them to check if your number has international SMS blocking enabled. Some numbers have "International SMS Blocking" enabled by default and need to be manually disabled.
Send an SMS command. Some carriers allow enabling or disabling international SMS via specific text commands. For example, China Mobile users can try sending "KTGJDX" to 10086 to enable international SMS service (specific commands may vary by region—confirm with customer service first).
Try a different phone number. If you have multiple phone numbers, try registering with another one. Different carriers and number ranges may use different SMS channels—switching numbers might solve the problem.
Long-Term Solutions for Stable Code Reception
Registration is just the first step—subsequent logins and operations also frequently require SMS verification codes. For long-term stable reception of Binance verification codes, prepare as follows:
Link an email as backup. Even if you registered with a phone number, it's strongly recommended to link an email in your account security settings. If your phone number can't receive codes, you still have email as a backup verification method.
Enable Google Authenticator. Google Authenticator is a time-based one-time password (TOTP) tool that doesn't depend on SMS or internet connectivity—just open the app to see the current code. Once enabled, many operations can use Google Authenticator instead of SMS, greatly reducing SMS dependency.
Keep your phone number active. Don't let the phone number registered with Binance go unused long enough for the carrier to reclaim it. Send at least one text or make one call per month to keep the number active.
Don't frequently change phone numbers. Binance's security system records your phone number information. Frequently changing numbers is not only cumbersome (each change requires security verification) but may also trigger security risk controls.
Alternative Verification Methods When Codes Don't Arrive
Beyond SMS verification, Binance supports multiple verification methods:
Email verification codes. A parallel option to SMS. Where verification is needed, you can usually select "Send Email Verification Code."
Google Authenticator. As mentioned above, once set up it serves as a verification method. It auto-refreshes every 30 seconds and is very convenient.
Binance Authenticator. Binance also has its own authenticator feature (Binance Authenticator), integrated into the Binance app, working similarly to Google Authenticator.
Security key. If you have a hardware security key like YubiKey, you can link it to Binance. This is the highest-security verification method.
It's recommended to enable at least two verification methods so you have alternatives when one doesn't work. For mainland China users, the most recommended combination is: email verification + Google Authenticator. Both methods don't depend on China's SMS channels and offer better stability.
In summary, while +86 phone numbers not receiving Binance verification codes is a common issue, there are plenty of solutions. Short-term, you can resolve it by checking blocking settings or switching to email registration; long-term, setting up multiple verification methods reduces reliance on SMS.
