As of my last update in May 2025, there isn't a legitimate "Telegram phone number finder bot" that can simply reveal someone's phone number if they have chosen to keep it private.
Here's why such bots generally don't exist or are ineffective:
Telegram's Privacy Settings: Telegram places a strong emphasis on user privacy. Users have granular control over who can see their phone number through their privacy settings. They can choose to make it visible to "Everybody," "My Contacts," or "Nobody."
Bot API Limitations: The Telegram Bot API, which thailand telegram mobile phone number list developers use to create bots, does not provide a function to retrieve a user's phone number if it's hidden in their privacy settings. Bots can typically only access information that a user explicitly shares with them or what is publicly available.
Ethical and Legal Concerns: Creating or using a bot to bypass privacy settings and obtain someone's phone number without their consent raises significant ethical and potentially legal issues.
What you might find, and why you should be cautious:
Bots that require interaction: Some bots might ask users to share their contact information directly. This is different from a bot that can automatically find a hidden number.
Third-party tools or services: You might encounter third-party tools or services that claim to find Telegram phone numbers. These are often unreliable, could be scams, and might violate Telegram's terms of service and user privacy. Using them could also expose you to security risks.
"OSINT" or Information Gathering Tools: There are OSINT (Open Source Intelligence) techniques and tools that might help find publicly available information associated with a Telegram account. In some cases, if a user has publicly shared their phone number elsewhere online and used the same username or other identifiable information on Telegram, these tools might find a connection. However, this is not the same as a bot directly revealing a hidden number within Telegram. The "Telegram Phone Number Checker" tool mentioned in the search results on GitHub requires you to already have the phone number and checks if it's associated with a Telegram account, potentially revealing the username and name if the privacy settings allow. It does not find hidden numbers.
