How to Fix Binance SMS Verification Code Not Received

2026/4/5 22 min

When logging in or withdrawing from Binance, you are often required to send an SMS verification code. However, clicking "Send" but not receiving the SMS is very common among users in certain regions. It’s not that Binance isn't sending it; rather, domestic carriers have very strict interception rules for overseas commercial SMS. Since policy tightening in 2021, mobile, Unicom, and telecom operators have independent SMS filtering rules, where even number blacklists/whitelists and merchant signature filings can affect delivery rates. This article breaks down the typical reasons why SMS isn't received and provides a backup plan of "switching to email if SMS fails." After reading this, you shouldn't panic when encountering this issue. For urgent logins, try switching to email verification on the Binance official site desktop version, or use the Binance official APP push notifications to bypass the SMS step. iPhone users who haven't installed the app can check the iOS installation tutorial first. Let’s go through the troubleshooting steps.

One Minute to Determine if the SMS was Actually Sent

The Binance backend places your SMS in a queue immediately after you click "Send." Under normal circumstances, numbers should receive it within 30 seconds, with occasional delays up to 2-3 minutes. If it exceeds 5 minutes, troubleshooting is required.

Step 1: Check the Sending Record on Binance

Enter the "Security" center of your account (you need to log in via email or 2FA first).
Select "Notification History" or "SMS Logs" on the left.
Check the status of the most recent SMS sending.

If the status shows "Sent Successfully" but you didn't receive it, it means the SMS was sent from Binance's side, but carrier interception or an issue with the receiving end occurred. If the status shows "Sending Failed" or "Invalid Number," then the issue lies with the number itself.

Step 2: Test if the Mobile Number Can Receive Overseas SMS

Test by sending an SMS verification code to your own number using a banking APP; if received, the number is normal. Then find a friend overseas to send an international SMS; if received, the overseas channel is clear. If you can receive both but still not the one from Binance, then Binance's SMS is being specifically intercepted.

Typical Cases of Carrier Interception

Interception Patterns for China Mobile Users

China Mobile has the strictest filtering for overseas commercial SMS, especially after 2022. Interception characteristics:

Keywords related to cryptocurrency (including Binance, BTC, USDT) trigger filtering.
SMS sending frequency exceeds the daily limit (usually 3 overseas commercial SMS per number per day).
The number has had suspicious activity recently (marked as a scam risk number).

Solution: Call the customer service hotline and apply for the "Overseas Commercial SMS Reception" whitelist. Tell the representative, "I need to receive verification code SMS from Binance," and they will open the relevant interception on the backend. It usually takes effect within 24 hours.

Situation for Unicom and Telecom Users

Unicom is relatively lenient but also has interceptions. Telecom has a separate "International Roaming SMS Switch"; numbers without roaming enabled cannot receive overseas SMS, which is off by default for ordinary domestic numbers.

Telecom user solution: Call the hotline and apply for "International SMS Reception," explaining that you need to receive overseas verification codes. It takes effect immediately after the representative enables it.

Unicom users can perform the same operation via their respective hotline.

Additional Restrictions for Virtual Operator Number Segments

Virtual operator numbers starting with 170, 171, 172, 165, and 167 have the lowest delivery rates for overseas SMS due to leasing from the major carriers and stricter regulation. Many segments simply cannot receive overseas SMS. It is recommended to switch to a real-name registered number for Binance.

Troubleshooting Incorrect Number Binding

Incorrect Area Code Selection is a High-Frequency Issue

Sometimes the country area code before the mobile number is selected incorrectly during registration. Domestic numbers must select +86. If you accidentally selected +60 (Malaysia) or +1 (USA), the SMS is sent to a number in another country, and your phone will never receive it.

How to judge: Log in to Binance (if still possible) and check the area code displayed for the bound mobile number in your personal profile. If it's not +86, it's bound incorrectly and needs to be modified.

Mobile Number has been Transferred or Suspended

Old users sometimes change their numbers. If the number used to register on Binance is a previous one that is no longer in use or has been recycled by the carrier, the SMS will be sent but cannot reach you.

Bound Mobile Number and Login Mobile Number are Inconsistent

Rare but existent: User A's account is bound to a secondary mobile number B. When A logs in, the SMS is sent to phone B, but the user forgot about B, leading to the impression that it's not being received.

Alternative Solutions When SMS Fails

Binance allows users to switch verification methods during login. If SMS doesn't work, you can log in just as well with email.

Switch to Email Verification During Login

After entering your password, you reach the 2FA page.
Click "Having trouble?" or "Switch verification method" at the bottom of the page.
Select "Send email verification code."
Binance will send an email with a 6-digit code to your registered email address.
It should arrive within 5 minutes; enter it to log in.

This process is a standard alternative supported by Binance and works for the vast majority of login scenarios.

Switch to Google Authenticator

If 2FA is enabled for the account, you can pass directly using the 6-digit code from Google Authenticator after entering your password, completely bypassing the SMS step. 2FA is the most stable and is strongly recommended to be bound.

Ultimate Solution if Email is Also Not Received

If the email also doesn't arrive (often due to unstable domestic access to Gmail), go through the customer support appeal process. Prepare:

The email used for registration (must be accessible).
Account UID (found in registration emails).
Both sides of your ID card.
A selfie holding your ID card.
The time and city of your last successful login.

Submit a ticket, and customer service will process it within 24-72 hours.

Preventive Measures: Removing SMS from the Critical Path

SMS verification is the most unstable link. It is recommended for long-term users to configure as follows:

Use email + 2FA for login, and do not rely on SMS.
2FA must be enabled (Google Authenticator or Authy).
SMS should only be a backup verification, not the primary channel.
Choose stable and accessible providers like Gmail, Outlook, or Proton for your registration email.

With this configuration, even if your mobile number cannot receive SMS on a given day, it won't affect your normal login.

Waiting Rules for Delayed SMS

Sometimes the SMS isn't missing; it's just slow. Typical delays:

Delay Time	Possible Reason	Action
1-3 minutes	Carrier queuing	Wait normally
5-10 minutes	Cross-gateway delay	Continue waiting
10-30 minutes	Released after interception	May arrive or be lost
Over 30 minutes	Likely lost	Switch to email verification

The resend interval must be ≥60 seconds. Clicking too fast will be flagged by the system as a risk, with a maximum of 5 sends per number within 24 hours; exceeding this will lock the number for the day.

FAQ

Q1: I received an SMS just now, why can't I receive it when I click send again?

A: Binance has a throttling protection of 5 times per 24 hours for SMS. Resending too many times in one day will lead to rate limiting. In this case, wait 24 hours for it to lift automatically, or switch to email verification.

Q2: I haven't changed my mobile number, why did I suddenly stop receiving Binance SMS?

A: Carriers have updated their interception rules in the last two years. Numbers that could receive SMS before might not be able to now. Call your carrier to enable the whitelist for overseas commercial SMS.

Q3: Is it easier to receive Binance SMS with an overseas number?

A: Delivery rates for numbers from the US, Singapore, Hong Kong, etc., are very high, with delays not exceeding 30 seconds. If you have an international mobile number, priority should be given to binding it.

Q4: Can I change the bound mobile number?

A: Yes. Security Center → Mobile Number Management → Change. You will need the old mobile number to receive a verification code. If the old number is no longer usable, go through the customer support appeal unbinding process, which requires ID verification.

Q5: Will not receiving SMS affect withdrawals?

A: Yes. By default, withdrawals require triple verification: SMS + Email + 2FA. If the SMS doesn't arrive, you cannot complete the withdrawal. Solution: Turn off SMS verification in the Security Center and keep only Email + 2FA, which is functionally equivalent and more stable.

Q6: How many times can I send an SMS in one day?

A: The official Binance limit is 5 times within 24 hours, with an interval of 60 seconds each. Exceeding this triggers risk control, and the SMS channel will be unavailable for that day, though other verification methods are unaffected.

Summary

The root cause of SMS not being received is the increasingly strict interception of overseas SMS by domestic carriers; it is not the fault of Binance or your number. When encountering this, remember three steps: first, call carrier customer service to apply for an overseas commercial SMS whitelist; second, switch to email verification during login; and third, set 2FA as the primary verification for long-term configuration, with SMS as a backup. Once configured, whether the SMS works or not will not affect your normal use, and both logins and withdrawals can be completed smoothly. Don't struggle with SMS; switching channels is the fastest way to resolve it.
