Telegram Username FAQ
Can I check Telegram usernames in bulk?
Yes. Upload a username list or use the REST API, select the required result tier, and download a result row for every submitted username.
Which Telegram username task should I select?
Use tg_username for registration and avatar, tg_username_activity for activity and membership signals.
Are all profile fields present for every username?
No. Optional values depend on the available result for that username and can be empty. They are supporting signals, not verified personal facts.
Does the check contact Telegram users?
No. Processing is passive: it does not message the account or require private-account login.
