Many people encounter the following issue when registering for Telegram: they cannot receive the verification code after entering their phone number (especially +86 numbers). They have tried various methods such as switching networks, restarting their phones, and waiting for a few minutes, but none have worked.

This problem is particularly common in 2025, possibly due to issues with SMS channels or "false positives" in Telegram's security mechanisms.

We believe you have searched for many solutions online, and the most common advice is to "try multiple times" or "switch to a clean network," but these are not effective and fail to explain the specific reasons. Only by identifying the root cause can we resolve the issue targeted.

This article will focus on the reasons why +86 phone numbers cannot receive verification codes and the corresponding solutions, hoping to help you.

Reasons Why +86 Phone Numbers Can't Receive Telegram Verification Codes

When registering or logging in to Telegram with a +86 phone number in China, the failure to receive verification codes usually falls into the following categories:

1. Abnormal Network Environment

This is a relatively common reason. Telegram is very sensitive to IP addresses and network environments. Frequent network switching or unstable proxy nodes may trigger the platform's risk control, resulting in no verification code being sent.

Common Scenarios:

• Unstable proxy network, disconnections, or timeouts

• Frequent automatic switching of proxy nodes in different regions

• Significant discrepancy between the current IP and historical login records for the same account

2. Phone Number Marked as High-Risk

If your phone number has been used abnormally, Telegram may restrict the sending of verification codes.

Common Scenarios:

• Using a virtual number or non-real-name registered number

• Frequently registering multiple accounts with the same phone number

• Multiple login failures or incorrect verification code entries within a short period

3. Frequent Verification Code Requests

Telegram imposes certain restrictions on frequent verification code requests. If you:

• Click "Send Verification Code" multiple times

• Enter the verification code incorrectly multiple times

• Repeatedly attempt to log in using different proxies

The system will enter a cooldown period, and verification code delivery will stop, which may last from 1 to 24 hours.

4. Congestion or Temporary Restrictions on Carrier SMS Channels

SMS carriers occasionally throttle or block international SMS messages, especially during peak hours or when multiple verification code requests are made within a short period.

Common Scenarios:

• Multiple verification code requests from the same phone number within a short period

• Delays caused by fluctuations in international SMS channels

• Congestion on SMS channels during peak hours

Solutions for Not Receiving Telegram Verification Codes

Only by understanding the main reasons why +86 phone numbers cannot receive Telegram verification codes can we provide targeted solutions.

Solution 1: Prevent Interception by Phone System or Apps

Sometimes the verification code has actually been sent but is intercepted by the phone's system or security software. Optimizing device and app settings can effectively resolve reception issues.

Specific Steps:

1. Check for SMS Interception

• Check your phone's spam SMS folder and block list to ensure the message was not intercepted

• Temporarily disable SMS interception or security software restrictions on Telegram

2. System Settings Optimization

• Android users: Ensure SMS permissions are enabled for Telegram

• iPhone users: Enable reception of SMS from unknown senders

• Maintain stable phone signal to avoid SMS loss due to poor connectivity

3. Telegram Optimization

Ensure Telegram is updated to the latest version to avoid bugs in older versions that may prevent verification code reception.

Solution 2: Optimize Network Environment

An unstable network environment or frequent IP switching can easily trigger Telegram's risk control, leading to delayed or failed verification code delivery. Optimizing network settings can significantly improve success rates.

Specific Steps:

1. Choose a Stable, High-Quality Network

• Use a stable Wi-Fi or 4G/5G network and avoid frequent network switching

• Avoid frequent switching between data sources

2. Configure Proxy Services

• Use a reliable VPN or proxy service to avoid unstable nodes

• Ensure UDP protocol support (some TCP-only tools may affect Telegram connectivity)

3. Optimize Network Routes

• Try routes from different countries, prioritizing Asian nodes like Hong Kong, Japan, or Singapore

• Avoid peak usage times; networks are typically more stable in the morning or late at night

4. Network Settings and Cache

• Use "Global Mode" to ensure all Telegram traffic passes through the proxy

• Clear device cache and restart the network before attempting to receive the verification code again

Solution 3: Use Isolated Browser Environments for Multiple Accounts or Proxy Services

When managing multiple accounts or frequently using proxy services, Telegram assesses account security based on device, IP, browser fingerprint, and other factors. Logging into multiple accounts on the same device or browser can easily trigger the platform's risk control mechanisms, resulting in delayed or failed verification code delivery.

To resolve this issue, each account requires an independent, secure, and stable login environment. This is why many users choose MostLogin Fingerprint Browser, which allows configuring independent IPs, generating unique browser fingerprints, and creating isolated cache and local environments for each account.

With MostLogin's powerful anti-detection capabilities, Telegram recognizes the environment as a trusted device, reducing the likelihood of triggering security mechanisms and providing reliable support for verification code reception in multi-account or proxy environments.

Specific Steps:

1. Create Isolated Environments

• Use MostLogin to create independent browser environments, unique fingerprints, IPs, time zones, and plugin configurations for each account to ensure no cross-interference between accounts.

• Name each browser environment for easier multi-account management.

• Avoid logging into multiple Telegram accounts on the same IP or environment; ensure each account operates independently.

2. Configure Proxy IPs

• Select stable nodes, such as those in Hong Kong, Japan, or Singapore, to ensure smooth connectivity.

• Assign independent IP addresses to each account to reduce multi-account correlation and minimize risk control triggers.

• Test if the IP can access the official Telegram website normally.

3. Maintain Network Stability

• Always use the same isolated environment when logging into an account; avoid switching devices or browsers arbitrarily.

• Avoid clearing cache or modifying browser fingerprint configurations to ensure Telegram recognizes the device as trusted.

4. Verify Login Status

• Log in to Telegram again in the isolated environment.

• Request the verification code and check if it is received normally.

• If reception fails, switch to a new proxy node or create a new isolated environment and try again promptly.

5. Secure Multi-Account Management

• Maintain separate records for each account environment, including IP, login time, and node settings.

• Regularly clean up unused or failed environments to improve management efficiency.

Solution 4: Ensure Accurate Device Time and Time Zone

Abnormal system time or time zone settings may also prevent verification code delivery.

Specific Steps:

1. Check System Time

Ensure the device's date and time match the actual time.

2. Align with Proxy Settings

When using a proxy, ensure the system time zone matches the region of the proxy node.

Summary

While the issue of +86 phone numbers failing to receive Telegram verification codes is common, it can be resolved by identifying the root cause. Different scenarios require different solutions. We hope this article helps you quickly register for a Telegram account.
