Telegram user ID vs phone number technical.
Telegram's identity system intricately weaves together phone numbers and User IDs to provide both unique identification and flexible user interaction. While the phone number is the foundational anchor for every account, the User ID serves as the true internal, unchanging identifier.
Here's the interplay between phone numbers and User IDs in Telegram:
Primary Registration Method: Every Telegram account is initially created and verified using a unique phone number (personal or an anonymous +888 number from Fragment). This number is the primary public-facing identifier that you use to log in and that others might use to find you (depending on your privacy settings).
Security and Authentication: The phone telegram number database number is crucial for receiving login codes, performing Two-Step Verification (2FA), and for account recovery. It's the "key" to proving ownership of your account.
Contact Discovery: When you enable "Sync Contacts," Telegram uses the phone numbers in your device's address book to identify which of your existing contacts are already on the platform.
