Generally, No (for legitimate services): Telegram's verification system primarily checks if a number can receive an SMS or voice call. As long as the virtual number service reliably delivers the verification code, Telegram usually cannot distinguish it from a traditional mobile number.
Recycled Numbers & "Burned" Numbers: The main issue arises with free or very cheap virtual numbers that are frequently recycled. If a number has been used previously to register a Telegram account (even by a different user) and that account wasn't properly deleted, or if the number is associated with a lot of spam activity, Telegram might temporarily block or flag it, preventing new registrations.
IP Address: While the virtual number hides your telegram number database phone ID, your IP address is still visible to Telegram. For maximum anonymity, combining a virtual number with a VPN is recommended.
Reliability of SMS Delivery: Some free or less reputable virtual number services might not reliably deliver SMS verification codes, making registration difficult.
Number Permanence: Temporary virtual numbers might expire after a certain period, potentially leading to loss of access to your Telegram account if you don't change the number or keep the virtual number active.
Account Suspension: While rare for legitimate virtual numbers, if a virtual number is associated with a lot of spam or abuse history, Telegram might suspend the account.
Cost: Paid virtual numbers require a subscription or per-use fee.
