Why Telegram Requires Phone Verification
Telegram, as a mainstream instant messaging application worldwide, requires users to verify their phone numbers during registration or login. This mechanism is primarily based on the following considerations:
- Account Security: Phone verification ensures the authenticity of account ownership and prevents malicious registrations and bot accounts
- Prevent Abuse: Limits bulk registration behavior and maintains platform ecosystem
- Account Recovery: Phone number serves as an important identity verification basis when accounts are locked or need to re-login
- Two-Factor Authentication: Works with passwords to provide higher-level account protection
Telegram Verification Code Types
Telegram mainly provides two types of verification code receiving methods:
SMS Verification Code
The most common verification method, Telegram sends a 5-digit verification code to the user's phone number. Verification codes usually arrive within 1-2 minutes and are valid for 10 minutes.
Voice Verification Code
When SMS verification codes don't arrive after a long time, Telegram provides a voice call option. The system automatically calls the user's phone number and announces the verification code digits via voice.
Telegram Verification Process

Common Verification Code Issues
What to Do If Verification Code Doesn't Arrive?
- Check if the phone number is entered correctly (including the correct international code)
- Confirm that the mobile network signal is normal
- Wait at least 2-3 minutes, as verification codes may be delayed
- Check if SMS blocking is enabled on your phone
- Try using the voice verification code option
How to Handle Expired Verification Code?
If the verification code expires, you can click the "Resend" button in the Telegram app, and the system will send a new verification code. Avoid frequent requests as this may trigger rate limiting.
Will Original Account Data Be Lost After Changing Number?
No. Telegram's change number feature automatically migrates all chat history, contacts, groups, and channels to the new number, ensuring data integrity.
Can Virtual Numbers Be Used for Registration?
Telegram allows registration with virtual numbers, but note that:
- Virtual numbers must be able to receive SMS or voice verification codes
- Virtual numbers from some regions may be restricted by Telegram
- Using virtual numbers may affect certain features (such as People Nearby)
Security Usage Recommendations

Regularly check and clear device logins that are no longer in use:
