How to Check Telegram Activity: Offline Time and Active Days

Telegram Activity Check returns signals associated with the check time. It does not prove real-time presence, message reading, or willingness to reply.

What this task actually answers

Telegram Activity Check returns signals associated with the check time. It does not prove real-time presence, message reading, or willingness to reply. Define the business question first and select the smallest service that answers it.

Prepare phone numbers before upload

Start with a list that has a documented source and permitted purpose. Verify country codes, deduplicate, remove spaces, brackets, hyphens, names, and notes, then save one phone number per line in TXT. Excel and CSV are not accepted upload formats.

Use the TXT-to-Excel workflow

Submit a small sample to the selected Telegram (TG) task. Record the service, input row count, operator, and check date. Export Excel when processing finishes, preserve the raw result, and match it back to the CRM by original number or internal ID.

Interpret output fields correctly

Telegram Registration Check returns the phone number and registration status. Activity Check may add User ID, username, offline time, active days, name, VIP, and frozen-status fields. Profile or full-format tasks have separate outputs.

The check most teams miss

Store offline time and active days with the check date. Use the same definition across batches and keep unavailable values unknown.

What the result cannot prove

Registration or activity signals do not prove identity, marketing consent, purchase intent, or a fixed conversion outcome. Pictures, nicknames, age, and gender must not be expanded into unsupported sensitive inferences.

Delivery and review checklist

Keep the source TXT and exported Excel. Reconcile input and output rows, exceptions, and missing values. Record provenance, purpose, check date, access, and deletion timing. Review the current fields on the Telegram (TG) service page.
