Why Can't I Get a Telegram Verification Code in 2025? Common Causes and Solutions Analyzed

In 2025, more and more users are encountering the same problem: Telegram cannot receive verification codes. Some people wait for a long time, and there is still no text message on their mobile phone; others try multiple times and still can't log in. Faced with this situation, users tend to be anxious because the verification code is the first step to enter Telegram. If you do not receive the code, you will not be able to complete the registration or access your existing account.

In fact, this phenomenon is becoming more common in 2025, and it is not necessarily due to a broken phone or a Telegram failure. The failure to receive the verification code is usually related to factors such as operator restrictions, network environment, and Telegram's security risk control. To help you find the cause faster and reduce unnecessary attempts, we will analyze the problem based on the latest information and provide clear, actionable solutions.

What is the Telegram Verification Code and Why is it So Important?

Telegram's verification code is a simple string of numbers sent to your phone to confirm that "this account is operated by you." This code is critical for protecting your chat history and personal data. For example, if a user loses their phone, the system sends a verification code to the mobile number, blocking unauthorized access.

Telegram uses verification codes to ensure that your mobile number is real and valid. The system also determines whether the account is secure based on the verification code. If your account is logged in multiple times on different devices, or if the operation seems unusual, the system may be stricter. The verification code is a key step for Telegram to determine your identity; once this step goes wrong, you may encounter the situation where Telegram does not receive the verification code.

Common Reasons for "Telegram Not Receiving Verification Code" in 2025

1. Mobile Carrier or Number Factors

In 2025, the most common reason for not receiving the code is related to the mobile operator or the number itself.

• Operator Filtering: Some operators automatically filter international text messages and block the verification code from Telegram as spam SMS.
• Network Congestion: Weak signal areas or peak SMS channel usage can cause the verification code to be delayed for a few minutes or longer.
• Virtual/VoIP Numbers: Telegram's security requirements are stricter in 2025. Virtual numbers, VoIP numbers, or numbers from code-receiving platforms are easily flagged as risky, leading to undeliverable text messages [1].

2. Network Environment or Device Issues

Another common reason is related to the network or device environment.

• Unstable Network: When the network is unstable, such as on public WiFi or in places with weak signals, Telegram may not properly trigger the verification code to be sent.
• Device Blocking: Outdated Telegram app versions, disabled SMS permissions, or the phone's system mistakenly putting the verification code into the spam folder can all prevent you from seeing the code.

3. Telegram Security Risk Control

Telegram's security system has increased risk control in 2025, which is a major reason for delayed or restricted codes.

• Frequent Resend Attempts: Clicking "Resend Verification Code" multiple times in a short period will cause the system to enter a protected mode and pause code sending.
• Multi-Device/Region Switching: Logging in from different devices or vastly different regions (e.g., China in the morning and overseas in the afternoon) in a short period will trigger the system to judge it as an abnormal operation, temporarily restricting the verification code [2].

How to Solve "Telegram Cannot Receive Verification Code" in 2025

Try Using a Different and More Stable Mobile Number

If you repeatedly encounter the issue, try changing your mobile phone number to one provided by a regular operator that supports international SMS. Real cases show that switching from a virtual or temporary number to a real physical SIM card significantly improves the success rate of receiving the verification code.

Use Telephone Voice Verification as an Alternative

When the text message is delayed or blocked, you can choose the "Voice call to receive verification code" method. Telegram offers voice verification codes as a backup solution for SMS. Select the "Call me" option, answer the call, listen to the digital code, and enter it to log in immediately.

Log in to the Telegram Web Version

The web version of Telegram often has a more stable network connection and may offer additional authentication methods, such as voice verification codes or "send to logged-in device." If you can't receive text messages on your mobile phone, switching to the web version can often bypass risk control and improve the success rate.

How to Avoid the "Telegram Cannot Receive Verification Code" Problem Again

Create an Independent Browsing Environment with Nstbrowser

For users who frequently log in to multiple accounts or encounter risk control issues due to an unstable environment, using a clean, independent browser environment is essential.

Nstbrowser is an anti-detect browser that is ideal for this scenario. It can automatically generate independent fingerprints and isolated browser environments for each account, making your operations appear more natural and credible to Telegram, and reducing the delay or failure to receive verification codes due to environmental abnormalities.

Nstbrowser allows users to create multiple independent browsing environments with one click, each with a unique browser fingerprint (including resolution, time zone, language, system information, etc.). This means that each Telegram account runs on a separate "virtual device" that the system recognizes as a different device. This way, even if you operate multiple accounts on the same computer, Telegram's security detection will not be triggered because the device characteristics are the same. For users who often encounter "Telegram cannot receive verification codes," this method can significantly improve the success rate of receiving verification codes and login stability.

This feature is part of Nstbrowser's Multi-Login solution, which is highly recommended for users managing multiple accounts on platforms like Telegram, Facebook, or Instagram [3].

Avoid Frequent Logins and Multi-Device Switching

Many reasons why Telegram cannot receive verification codes are not system failures, but risk control caused by users' own login habits. Try to use a stable device and avoid logging out and logging back in frequently. Additionally, keep the network environment stable and avoid frequently switching between WiFi, mobile data, or using unfamiliar proxies in a short period of time. Too frequent network changes can also cause the system to mistakenly believe the account is at risk, delaying the sending of the verification code.

Frequently Asked Questions (FAQs)

1. Why do many people not receive verification codes on Telegram in 2025?

Stricter platform risk control, enhanced filtering of international SMS by operators, and increased use of virtual numbers lead to delays or non-delivery. Network restrictions in some regions can also cause Telegram verification services to be unstable.

2. What should I check first if I can't get a verification code on Telegram?

Check your mobile phone signal, ensure your bill is not in arrears, check if SMS interception is turned on, and verify that the country code (e.g., +1, +86) is filled in correctly.

3. Can logging in to the Telegram web version solve the problem?

Yes, very likely. The web version's network is usually more stable and also offers additional authentication methods, such as voice verification codes or "send to logged-in device."

4. Why is it easier for Telegram to not receive verification codes when using a virtual number?

Telegram has very strict risk control over virtual numbers, which are often used by multiple people and flagged as high-risk. It is recommended to use a real mobile phone number from a regular operator.

5. How can Nstbrowser help with Telegram verification issues?

Nstbrowser creates an independent browsing environment with a unique digital fingerprint for each account. This isolation prevents Telegram's risk control system from linking your accounts or flagging your device as suspicious due to frequent logins or multi-account activity, significantly improving the success rate of receiving verification codes.
