About ZelNum

ZelNum is a bulk phone and email verification platform with 58 check tools in one workflow. It checks WhatsApp and Telegram registration, carrier and line-type data, email deliverability, and flags VoIP and disposable contacts — built for marketers, CRM teams, and anyone whose outreach depends on clean contact data. Start with free tools for single lookups, then scale with bulk CSV uploads (up to 2M rows per file) or the API for automation. Results come back in clear buckets — valid, invalid, unknown — so you know exactly what you paid for. Pricing starts at $0.5 per 10K lookups.
