“Who can see my phone number?”
Tip: Always choose “Nobody.” This ensures your phone number is never displayed on your public Telegram profile, regardless of who is viewing it.
“Who can find me by my number?”
Tip: After setting “Who can see my phone number?” to “Nobody,” choose “My Contacts.” This means only people whose numbers are saved in your phone’s address book (and who also use Telegram) can find your profile by searching for your number. If you want maximum isolation, you can choose “Nobody” here as well, but then you’ll only be discoverable via your username or group membership.
2. Embrace and Utilize Usernames
Usernames are Telegram’s premier privacy feature.
Tip: Create a unique and memorable @username.
Usage: For all interactions with people you don’t know personally, in public groups, or for professional networking, share your username telegram number database instead of your phone number. This allows others to find and message you without ever seeing your private number.
Control whether Telegram accesses your phone’s address book.
“Sync Contacts” Toggle:
Tip: If maximum privacy is mobile numbers and business growth your goal and you prefer to add everyone manually, toggle this OFF. This prevents clean email your phone’s entire address book from being uploaded to Telegram’s servers.
