Everything you need to know about MUMU Filter's phone number screening service.
Upload your phone number list in TXT format, and our system checks each number against WhatsApp's registration database. Results show which numbers are registered, actively used, or banned — and can include profile details for deeper segmentation.
Our platform supports phone number detection across 60+ social platforms — including Line, Zalo, Viber, Facebook Messenger, Instagram, and more. You can check numbers against one or multiple platforms depending on your needs.
We support TXT file format. Upload your phone numbers in a single column and our system automatically processes all entries. Results can also be exported in TXT format.
Our detection accuracy exceeds 99.5% for most major platforms. We query live platform databases in real-time for current and reliable results. Accuracy may vary slightly by platform and region.
Beyond just checking registration, active status detection determines whether an account is actively being used by analyzing recent online activity, last seen timestamps, and engagement patterns. This helps you target users who are truly reachable.
Create a free account at login.mumuapi.com, upload your phone number list, select the platforms to check, and receive your results in minutes. No technical expertise required — our platform is designed for marketers and business teams.
We support phone numbers from over 200 countries and territories worldwide, covering 60+ social and messaging platforms. Our system automatically detects and normalizes international phone formats.
Our AI profile analysis examines profile photos to estimate age, gender, and region. This helps you build richer audience segments for more targeted outreach and personalized messaging campaigns.
