FAQ

Telegram Number Check API FAQ

Answers about limits, privacy, and bot-risk signals.

Rate limits?

Default API plans support up to 10K numbers per bulk request. Higher sustained throughput is available for enterprise accounts.

Privacy?

The API is designed for verification and list hygiene workflows. It does not send a visible Telegram message to the checked user.

Bot detection?

Bot detection is returned as a risk signal, not an absolute label. Pair it with account age, duplicate patterns, activity, and your own review rules.

Is this a Telegram API number check and Telegram phone lookup API?

Yes. This API serves as a Telegram API number check endpoint and a Telegram phone lookup API. Pass any E.164 number and receive registration, account age, and bot-risk signals in real time.
