About

We are the experts for phone number lookups to determine phone line type. Do you need to know if phone numbers are mobile, landline, toll-free, VOIP, or fake/invalid? We cover all line types and all U.S phone companies. Run a phone number search above to see our uncanny accuracy. You can automate phone validator lookups with the phone validator API. Join the many app developers and marketing agencies who already use the API to keep their project phone numbers validated in real time. Our batch processing makes updating your phone lists easy. To run a phone number batch, just upload your CSV file and we'll do the work and email your file back.

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.
