Q&A
FAQ
Yes. Although some Viber users hide last seen, GeekNums evaluates multiple indirect signals: avatar update frequency, status changes, nickname history and participation in public Viber Communities. Without an exact Last Seen, profile activity and behavior signals still reliably tell whether a user is "recently active" or "long abandoned".
Absolutely. Results export as CSV with fields preconfigured for the Viber Business Messages API (number, country code, activity tier, gender, age range tags), ready to import into Viber's official business platform or third-party Viber marketing tools. Start your first outreach with "valid + highly active" data, and use a gentle "greeting + value" approach for moderately active users to avoid reports.
We focus on core Viber markets: Russia, Ukraine, Belarus, Bulgaria, Greece, Iraq, Saudi Arabia, Israel, the Philippines, Vietnam and more. Russia, Ukraine, Iraq, Saudi Arabia and the Philippines have the highest Viber penetration, with the most complete accuracy (≥98%) and activity data. Registration rates vary by country, so test a small sample first before planning large-scale filtering.
