# ZelNum

Canonical: https://www.softwareadvice.ie/software/661601/ZelNum-formerly-BulkChecker

> ZelNum helps teams make better decisions with phone and messaging data before that data reaches a CRM or campaign. Its core tools, WhatsApp Number Checker and Telegram Number Checker, verify whether phone numbers are registered on the corresponding platforms and, where available, return activity or profile signals. Teams can also validate phone status, look up carrier and line-type information, and run additional number or email checks across supported social, messaging, and crypto services. Users can perform individual lookups, upload CSV or TXT files for bulk processing, or connect through the API for automated batch workflows. Results can be segmented and exported for list cleaning, lead qualification, outreach preparation, and risk review. Free manual tools are available, while paid checks use pay-as-you-go pricing with no subscription requirement. ZelNum provides verification signals, not identity proof; use authorized data only.
