In 2025, more and more users are encountering the same problem: Telegram cannot receive verification codes. Some people have waited for a long time, and there is still no text message on their mobile phone; Some people try multiple times and still can't log in. Faced with this situation, users tend to be anxious because the captcha is the first step to enter Telegram. If you do not receive the verification code, you will not be able to complete the registration and enter the original account.
In fact, this phenomenon will be more common in 2025, not necessarily because the phone is broken, nor is it necessarily because of Telegram failure. The failure to receive the verification code is usually related to factors such as operator restrictions, network environment, and security risk control. In order to help you find the cause faster and reduce unnecessary attempts, we will take you to analyze the problem based on the latest information and real cases, and provide clear and actionable solutions.
Telegram's CAPTCHA is a simple string of numbers. It will be sent to your phone to confirm that "this account is operated by you". CAPTCHAs protect your chat history and personal data. For example, a user loses his phone and someone wants to log in to Telegram with his number. However, the system sends a verification code to the mobile phone, and without entering the verification code, you cannot enter the account. This step blocks the risk. Therefore, when Telegram cannot receive the verification code, it often means that the system cannot complete this step of confirmation.
Telegram uses verification codes to ensure that your mobile number is real and valid. Only a valid number can be successfully registered or logged in. The system will also determine 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. For example, if a user changes his device to log in multiple times in a short period of time, Telegram will delay sending a verification code to protect the account from being stolen. Therefore, the captcha is a key step for Telegram to determine whether you are who you are or not. Once this step goes wrong, you may encounter a situation where Telegram does not receive the verification code.
In 2025, many users will encounter Telegram not receiving verification codes, and the most common reason is the operator or the mobile phone number itself. Some operators will automatically filter international text messages and block the verification code from Telegram as spam SMS. Users can't receive anything on their mobile phones, but in fact, the verification code has long been blocked by the system. There are also users whose signal is weak in their area, or the SMS channel is at its peak, and the verification code will be delayed for a few minutes or even longer.
In addition, if you are using a virtual number, VoIP number, or code receiving platform number, the probability of the verification code not being sent will be higher. Security requirements are stricter in 2025, and such numbers are very easy to be flagged as risky numbers by Telegram, resulting in text messages being undeliverable. Some users register multiple Telegram accounts with one number in a short period of time, which will also trigger the system's risk control. If the system determines that there is an abnormality in this number, it will stop sending the verification code. This is how many "telegram can't receive verification code" situations happen.
Another common reason is related to the network or device. When the network is unstable, such as in public WiFi or places with weak signals, Telegram may not properly trigger the verification code to be sent. someone tried to log in on the café's public network, but the verification code never came; It is quite common to receive text messages immediately after switching to mobile data when you get home.
The device itself may also block the verification code. Some users have outdated versions of Telegram App that are not compatible with the system, causing the verification code to fail to trigger normally. There are also some mobile phones that have turned off SMS permissions, or the system has mistakenly put the verification code into the spam SMS folder, making users mistakenly think that the text message has not been sent. Corrupted app cache can also cause abnormal display, making people think that "Telegram did not receive the verification code", but in fact the text message has already been delivered.
Telegram's security system will increase risk control in 2025, which is also an important reason why many people do not receive verification codes. If you click "Resend Verification Code" multiple times in a short period of time, the system will automatically enter protected mode and pause the verification code sending. Some users frequently log in to the same account on different devices in a day, and the system believes that there is a risk of theft, and the verification code is directly delayed.
Logging in from different regions in a short period of time will also trigger risk control. For example, if an account logs in in China in the morning and is logged in overseas in the afternoon, the system will judge it as an abnormal operation. At this time, the verification code will be temporarily restricted, resulting in the situation of "Telegram cannot receive the verification code". Telegram's security model prioritizes account security, so if the system feels it's risky, the verification code will likely not be delivered immediately.
If you repeatedly encounter the situation of "Telegram cannot receive verification code", you can try to change your mobile phone number. It is best to use a mobile phone number provided by a regular operator that supports international SMS. For example, user Xiao Li registered with a virtual account of a domestic operator, and after repeatedly failing to receive the verification code, he received the verification code within 5 minutes after changing to a real physical card.
When the text message has not arrived, you can choose the "Voice call to receive verification code" method. Many users find that when text messages are blocked or delayed, they receive a voice prompt code over the phone – they can log in immediately. For example, if a user cannot receive SMS in an environment with a weak WiFi signal, switch to voice verification and immediately connect and enter the received digital code. According to the information, Telegram offers voice verification codes as a backup solution for SMS. This step is simple, first register/log in to the Telegram interface, select the "Call me" option, answer the call and listen to the number, and then enter it.
For some new users, Telegram may support "email sign-up" as an auxiliary method in some regions. However, a reminder: while you may have completed the initial registration via email, you still need to link your mobile phone number to your account. Also, this is not a method supported by all regions. The information points out that Telegram only sends verification codes by SMS or voice by default, and the email is mainly used for "two-step verification" recovery. Therefore, if you frequently encounter the problem of "Telegram cannot receive verification codes" in 2025, you can consider: register your email address first, and then bind your mobile phone number as an alternate verification path.
If you want to reduce the situation of Telegram not receiving verification codes in 2025, the most important point is to keep your account information stable. You need to make sure that your mobile number is always valid and doesn't let the number go down or be in arrears for a long time. Many users find that they cannot receive the verification code at all when logging in because of changing their numbers or deactivating their old numbers. At the same time, also update the Telegram App regularly. Older versions may have compatibility issues, resulting in verification codes not being sent smoothly or verification failures. These problems often disappear after an update. Also, try not to use virtual numbers or coded numbers. Real cases show that some users registered for Telegram with a code number and could receive a verification code at first, but after a few weeks, the system directly marked the number as a risk number, and they never received any login text messages again. This is very common in 2025, so the main account must use the mobile phone number of the regular operator.
Many reasons why Telegram cannot receive verification codes are not system failures, but risk control caused by users' own login habits. For example, a user logs in to the same account on three devices: mobile phone, tablet and computer in one day. When I tried to log in again that night, I couldn't receive the verification code at all, because the system judged it to be "abnormal behavior". To avoid this, you can try to use a stable device and don't log out and log back in frequently. In addition, keep the network environment stable and avoid frequently switching 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 that the account is at risk, delaying the sending of the verification code.
When encountering "Telegram cannot receive the verification code", many users will choose to try to log in to the web version of Telegram, because the network connection of the web version is more stable and the probability of successful delivery of the verification code is higher. However, if you have logged in to multiple accounts on your device or your browser fingerprint is unstable, Telegram's risk control system may still intercept the verification code.
This is where it is important to use a cleaner, more independent browser environment. DICloak Browser is a tool suitable for this scenario, which can automatically generate independent fingerprints and independent browser environments for each account, making the operations recognized by Telegram more natural and credible, and reducing the delay or failure to receive verification codes due to environmental abnormalities.
Create an independent browsing environment with fingerprints
DICloak 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.
Multi-account management
For users who manage multiple Telegram, Facebook, Instagram, or TikTok accounts, DICloak can avoid confusion between multiple accounts and make your web login experience smoother.
In 2025, stricter platform risk control, enhanced filtering of international SMS by operators, and increased use of virtual numbers will lead to delays or non-delivery of verification codes. Network restrictions in some regions (such as Chinese mainland) can also cause Telegram verification services to be unstable, and these factors combine to make "Telegram not receiving verification codes" more common.
You can first check the mobile phone signal, whether the bill is in arrears, whether SMS interception is turned on, and then check whether the area code is filled in correctly. Many people fill in the wrong area codes such as +1, +86, +60, resulting in the verification code being sent to the wrong country. If you have frequently requested verification codes, you may also be temporarily restricted by the system.
Very likely. The web version of the network is usually more stable and also offers 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 break through risk control and improve the success rate.
In 2025, Telegram will have very strict risk control over virtual numbers and code receiving platform numbers, which are often used by multiple people, and the system will directly refuse to send verification codes. Therefore, even if the network is normal, you may still have the situation of "Telegram cannot receive the verification code", it is recommended to change the real mobile phone number.
You can try to use voice verification, log in to the web version, clean up the old device, and if not, you can contact the Telegram support team and provide the mobile phone number, region and screenshots of the error. Using an independent browsing environment (such as an anti-association browser) can also reduce the risk control of CAPTCHAs caused by abnormal environments.
