Some notable examples include:
Bellingcat's Whatsapp Phone Number Checker: -line tool (also accessible via Google Colab) allows users to check if a phone number is associated with a Whatsapp account.

It's important to note that this tool respects privacy settings and does not reveal hidden phone numbers.
wilcode/Whatsapp -phone-number-checker (Apify Actor): Offered on the Apify platform, this tool likely serves a similar purpose to Bellingcat's, allowing users to check phone number registration belarus whatsapp number data on Whatsapp via the Apify API. Its functionality is also expected to be bound by Whatsapp 's privacy settings.
unnohwn/Whatsapp -checker (GitHub): This Python tool, available on GitHub, aims to check Whatsapp accounts using phone numbers or usernames. It can verify account existence, download profile pictures, and provide user information in JSON format, leveraging the Telethon API.
Key Considerations and Limitations:
Privacy First: Whatsapp 's fundamental commitment to user privacy means that tools cannot generally bypass users' privacy settings to reveal information they have chosen to keep private, such as their phone number.
Verification vs. Information Retrieval: Most "account checkers" focus on verifying the existence of an account associated with a phone number or retrieving publicly available data, rather than uncovering private information.
API Requirements: Tools like Bellingcat's and unnohwn/Whatsapp -checker often require users to obtain their own Whatsapp API ID and API Hash, necessitating a basic understanding of the Whatsapp developer platform.
