Whether you're signing up for the first time or trying to log back in, Telegram's verification code is essential for accessing your account. But what if the code never arrives? If you're wondering why Telegram is not sending the verification code, you're not alone. This article explains the possible causes and walks you through practical, effective solutions, so you can regain access to your account quickly and securely.

Why Are You Not Getting Telegram Verification Code?

Telegram sends a one-time password (OTP) via SMS or call to verify your identity. If that message doesn’t reach you, the problem might lie in any of the following areas:

1. Wrong Phone Number

This is the most likely reason why the Telegram SMS doesn’t arrive. It sounds simple, but a typo (like an incorrect country code) in your number can completely block verification. 

2. Unstable Internet Connection

Even though the code comes via SMS, Telegram sometimes uses in-app delivery methods requiring internet, especially if you're already signed in on another device.

3. Geo-Blocking Issues

Certain countries or regions may block the Telegram server or restrict code delivery services. This is common in countries with strict digital surveillance or censorship.

Pro Tip

If you're in a restricted region or facing issues receiving the verification code, using a VPN — like UFO VPN — can help.
Connect to a stable server (such as a Russian VPN server) to bypass blocks and verify your account smoothly.

4. Denied SMS Sending by Carrier and Filter

Some mobile operators block SMS from certain short-codes or international services. In addition, you may have enabled SMS filtering settings on your device, which might also result in Telegram not sending the SMS code.

5. Too Many Code Requests

It’s understandable to try many code attempts when encountering the problem of the Telegram code not reaching your device. However, requesting the code multiple times within a short window may temporarily block further attempts.

6. Device or App Issues

Outdated apps, bugs, or device-specific issues can interfere with SMS reception.

7. Virtual Number Not Accepted

Telegram may reject virtual or VoIP numbers from services like Google Voice or TextNow.

Fix 3. Diagnose Your Network Connection

If you're relying on Wi-Fi or mobile data for Telegram access, ensure your connection is stable. For example, you can move closer to the router or switch between Wi-Fi and mobile data to see if it works. Alternatively, you can also switch to a different network provider.

Fix 4. Restart Your Device

A simple reboot can refresh your network and app settings, which will resolve potential temporary software or network issues. Then, you can try to reconnect to the network and request the verification code again.

Fix 5. Reset SMS Filtering

Some filtering features may block important messages like SMS codes. For instance, iPhones may block unknown senders if you have enabled this feature. You can go to Settings > Messages > Unknown & Spam and disable filters.

Fix 7. Use the Call Me Option

If SMS doesn’t work, Telegram offers a voice call to deliver the code. Tap the Call Me option and wait for Telegram’s call to your phone. Listen to the call carefully and note down the provided SMS code.

Use the Call Me option to get the SMS code.

Fix 8. Waiting Before Requesting Again

Sometimes, it takes time for Telegram to send SMS to you. Be patient and wait for a while. Avoid spamming the "resend code" button because it may be spotted as a fraudulent activity. Rest 5-10 minutes before reattempting to check if you’ve gained any delayed verification message from Telegram.

Fix 9. Check the Updates

An outdated app can interfere with message delivery. You can go to your app store and check if there are any updates available for Telegram. Also, if your phone’s operating system is ready to update, do it. You can try getting the verification code again after updating.

Fix 10. Reinstall Telegram

For a more direct approach, uninstalling and reinstalling the app can resolve some configuration or permission issues.

Fix 11. Try Telegram X

Telegram X is an official alternative app developed by the Telegram team. It offers improved speed and performance, and may work better on certain devices where the standard Telegram app has bugs or glitches. Switching to Telegram X has helped some users receive verification codes more reliably.

FAQs

1. Can I use a virtual number for Telegram verification?

Telegram typically does not support virtual numbers (VoIP services) like Google Voice or TextNow for verification purposes. These numbers are often blocked to prevent spam or fraudulent accounts. If you're not receiving your code, try using a real SIM card number or switch your IP address using a VPN to see if that helps.

2. How long does it take to receive a Telegram code?

Telegram codes usually arrive within a few seconds to 1 minute. However, depending on your network quality, country restrictions, or server load, it may take longer. If you haven’t received the code within 2–3 minutes, you should try resending it or switching to a different network.
