Validation uses Google's libphonenumber metadata — the same library powering Android dialers and WhatsApp itself. Numbers detected as MOBILE or FIXED_LINE_OR_MOBILE are most likely to have a WhatsApp account. All processing happens in your browser — nothing is uploaded.
Powered by libphonenumber — the same metadata Google and WhatsApp use. Detects fake length, wrong prefix and impossible numbers.
Flags MOBILE and FIXED_LINE_OR_MOBILE numbers so you only message lines likely to have WhatsApp.
One-click export for Wati, AiSensy, 360dialog or the Meta Cloud API — all in proper E.164 format.
