NumberChecker
Bulk verify phone, WhatsApp, RCS, iOS, and emails.
Upload CSV contact lists to verify phone number status, WhatsApp activity, WhatsApp age and gender, RCS, iOS, Gmail, Yahoo, and Outlook signals at scale.
Hi Product Hunt,
I built NumberChecker.cloud to help marketers, agencies, and data teams clean contact lists before spending money on campaigns.
It supports bulk CSV checks for phone number status, WhatsApp availability, WhatsApp age and gender signals, RCS, iOS status, carrier/network lookup, and Gmail/Yahoo/Outlook email verification.
The goal is simple: remove bad, inactive, or unsuitable contacts before outreach so teams can reduce wasted spend and improve campaign quality.
I’d love feedback from anyone working with large contact lists, WhatsApp campaigns, SMS, email outreach, or lead generation.
