FAQ
GeekNums checks numbers on many common messaging, social and business platforms, including WhatsApp, Telegram, Viber, LINE and Zalo. Check methods and returned information vary by platform, and results follow each platform's mechanism. Platform support is continuously updated; see the current GeekNums platform list for details.
A single GeekNums task supports up to 1 million records, so you can upload large batches without splitting files. Processing time varies with volume; for example, 1 million Telegram records take about 20 minutes, depending on the platform, task queue and network conditions. You'll be notified when the task finishes and can view the results in your task history.
GeekNums returns number status based on each platform's actual check results and minimizes errors caused by number formats or duplicate data. Since platforms expose different information and mechanisms, the result types vary by platform. Results returned by the system are authoritative.
Speed differs by platform because access mechanisms, response times and check methods vary. GeekNums processes tasks based on each platform's conditions and advances bulk tasks in real time. After you upload data, tasks run automatically, so you don't need to stay on the page.
GeekNums checks international numbers worldwide from any country or region. To make sure the region is identified correctly, upload numbers in full international format, such as +447911123456. The system recognizes 220+ country and region codes.
No. Once a bulk task is created, the system processes it in the background, so you can leave the page or keep working. Large tasks continue processing and you'll be notified when they finish.
Yes. New users get $5 in free credits on sign-up, no credit card required. You can also verify a single WhatsApp or Telegram number for free on the homepage without logging in.
