Q&A
FAQ
Yes. Telegram does let users hide "last seen". For these accounts, GeekNums switches to indirect evaluation: it analyzes username activity, profile (bio/avatar/nickname) update frequency and public group/channel participation to infer real activity. Even if the user hides their status completely, public behavior data shows whether they use Telegram heavily or have abandoned it.
Results can be exported as TXT/CSV/Excel and imported directly into Telegram bulk tools, TG bots or channel management systems. Whether accounts get banned depends on your sending strategy, not on filtering. To reduce risk: ① prioritize "valid and highly active" data; ② limit sending frequency (no more than 50 per day for new accounts, 200 for established ones); ③ avoid sensitive words and obvious ad copy; ④ use intervals and random delays.
Numbers from every country and region are supported, with no country restrictions, and up to 1 million per upload. Telegram users are concentrated in Russia, Southeast Asia, the Middle East, Latin America and Europe, where accuracy and data coverage are the most complete.
Yes. If a number is linked to an @username (e.g. @example_user), you can search that username on Telegram to send a DM or invite them to a channel/group without knowing their phone number. This is a key advantage of Telegram marketing over WhatsApp: precise username-based outreach that also protects privacy.
