About
ZelNum is a phone number and messaging app checker for teams that need to validate WhatsApp, Telegram, LINE and Zalo accounts, clean contact lists, and enrich phone records with carrier data. It runs 39 different checks in real time against live network data rather than cached results, returning practical status fields like registration status, active status, carrier, line type, country, and VoIP risk signals.
You can check single numbers through the web interface, upload CSV or TXT files for bulk verification of thousands of records, or integrate the API into your CRM, fraud prevention workflow, or compliance review process. The platform segments results into clean, inactive, and risk-review categories so you know which records are safe to use.
ZelNum charges per check or per 10,000 rows with no subscription, no monthly fees, and no minimum commitment. You buy prepaid credits once and spend them whenever you need verification work, with rates starting at $0.50 per WhatsApp check and $1.50 per Telegram check.
Every check runs live at query time against the network's current answer, never from a cached database. The platform covers 39 different verification signals across multiple messaging apps and phone validation in one workflow, with global coverage across international carrier networks and messaging platforms.
- Problem
- Contact lists degrade over time as phone numbers are recycled, accounts become inactive, or users switch platforms. Teams risk wasting resources on invalid numbers or sending messages to inactive accounts.
- Solution
- ZelNum validates phone numbers and messaging app accounts in real time, returning registration status, active status, and risk signals so you can clean lists before they reach your CRM or fraud queue.
