Prevention of Data Correlation:
Your phone number is a common data point used by various services. If exposed across multiple platforms, it can be used to link your activities, identities, and personal data from disparate sources, creating a more comprehensive (and potentially exploitable) profile of you.
Control Over Digital Footprint:
Protecting your phone number minimizes telegram number database the digital breadcrumbs you leave behind, allowing you greater control over who can connect your online presence to your real identity.
Telegram's "Privacy by Design" principles are evident in its approach to phone numbers:
Granular Visibility Settings: As a core feature, Telegram allows users to explicitly control who can see their phone number ("Everybody," "My Contacts," or "Nobody") and who can find them by their number ("Everybody," "My Contacts," or "Nobody"). This gives users direct power over this crucial piece of data.
Usernames as a Primary Contact Method: By allowing users to set a unique @username, Telegram effectively decouples online interaction from the phone number. You can share your username widely without ever exposing your underlying phone number.
Fragment (+888) Anonymous Numbers: Telegram's introduction of blockchain-based anonymous numbers from Fragment provides a way to register and use Telegram without any link to a traditional, personally identifiable phone number. This offers the highest level of phone number privacy from the outset.
Prioritization of In-App Code Delivery: When logging into a new device, Telegram prioritizes sending the verification code to your active Telegram sessions on other devices, rather than immediately resorting to SMS. This enhances security by keeping the code within the encrypted Telegram ecosystem and reducing reliance on less secure SMS channels.
