About
ZelNum is a web-based verification and data-cleansing platform for businesses, sales teams, marketers, and developers. It helps users verify WhatsApp, Telegram, and phone numbers, check carrier and line-type information, and enrich contact records with country and phone data. Users can run individual checks, upload CSV or TXT files for bulk processing, or connect through the API for automated workflows. With more than 40 verification checks available, ZelNum helps teams clean contact lists, improve data quality, qualify leads, prepare outreach campaigns, and review potential risks. Free manual tools are available, while paid checks use transparent pay-as-you-go pricing with no subscription required. ZelNum provides verification signals, not identity proof, and should be used only with authorized data.
