Hey Product Hunt!
I’m Hamid, the maker of NumberChecker.cloud.
I originally built this because working with large contact lists was frustrating. Before running a campaign, you often don’t know how many numbers are actually active, which ones use WhatsApp, whether an email is active, or which communication channel is worth using.
So I built one platform where you can upload a list and run different checks in bulk — including:
• WhatsApp number status
• Phone number activity
• WhatsApp age & gender signals
• RCS availability
• iOS status
• Gmail, Yahoo & Outlook verification
• REST API for automated workflows
One thing I cared about a lot was keeping it simple: upload → choose the check → download the results.
There are no subscriptions either. Credits are pay-as-you-go.
I’ve mostly built NumberChecker.cloud myself, so launching it publicly is a pretty big moment for me 😄
I’d genuinely love feedback from the Product Hunt community — especially on the product, onboarding, pricing and anything that feels confusing or could be improved.
Thanks for checking it out!
