LeadAI
HLR Lookup: Free Mobile Number Information Online
Get mobile number information online — carrier, country or region, number type, and validity status — before every SMS or WhatsApp campaign. 100% free, no registration.
Why this product exists.
Half your SMS or WhatsApp list is disconnected, invalid, or wrong carrier — and you only find out after you've paid to send.
High invalid-number rates flag your sender ID, throttle delivery, and tank reply rates across the whole campaign.
Existing HLR tools want a signup, a credit card, and a per-lookup fee before you've even tested one number.
GDPR, no GPS tracking, no PII storage — most lookup tools are sketchy about all three.
What LeadAI delivers.
Validate one number or paste a whole list. Get carrier, country, region, number type and validity in seconds.
See whether a number is actually WhatsApp-active before you spend on a WhatsApp campaign.
Optimized global lookup engine returns metadata in ~0.1s — ideal for high-demand regions like Pakistan, Algeria, Indonesia.
Strict no-log policy. No stored numbers, no third-party data sales, no GPS tracking. GDPR-compliant out of the box.
From chaos to clarity.
