Registration: Yes, you must use a phone number to register for a Telegram account. It’s your primary identifier for the service.
Initial Discovery: When you first join Telegram, if people have your phone number in their phone’s contact list and they also use Telegram, they will see you appear in their Telegram contacts.
Telegram’s Privacy Settings are Key:
Telegram provides granular control over who can see your phone number. You can find these settings by going to:
Settings > Privacy and Security > Phone telegram number database Number
Everybody: If you select this, anyone on Telegram will be able to see your phone number if they look at your profile or if they get added to a group with you.
Within this section you’ll usually have three main options:
My Contacts: Only people who explore pay-per-click (ppc) advertising are already in your phone’s address book (and who also use Telegram) will be able to see your phone number on Telegram. People outside your contacts won’t.
Nobody: This is the most private belgium numbers option. If you select “Nobody,” no one, not even your contacts, will be able to see your phone number through Telegram.
