Overview
What is the number scanner?
Know who is on WhatsApp first.
The number scanner answers one question: does this phone number have WhatsApp? You give it a list of numbers—from a CSV, spreadsheet, or paste—and it checks each one. The result: a cleaned list of numbers that are on WhatsApp. Use it before campaigns to avoid sending to invalid numbers and improve delivery.
Bulk-check which numbers have WhatsApp. Upload a list and scan instantly like a campaign. Same device infrastructure, different purpose. Results show valid vs invalid. Export valid only.
The dashboard shows each number with status: Has WhatsApp or No WhatsApp. Valid rate displayed. Upload CSV or paste. Scan All to run. Export Valid to download the cleaned list.
Upload CSV or paste
Provide a list of phone numbers. Upload a file or paste directly. Same format as contact import—numbers with country code.
Bulk verification
Check thousands of numbers at once. Run it like a campaign—same device infrastructure, different purpose. Scan instantly.
Valid vs invalid
Results show which numbers have WhatsApp and which do not. Has WhatsApp or No WhatsApp. Valid rate displayed (e.g. 60%).
Export valid only
Export the cleaned list. Remove invalid numbers before sending campaigns. Reduce failed sends and improve delivery metrics.
How bulk number verification works
Upload a CSV or paste a list of phone numbers. The scanner checks each one against WhatsApp and returns which have accounts. Run it like a campaign—same device infrastructure, different purpose.
Why verify before sending: sending to invalid numbers wastes credits and can trigger rate limits. Pre-scan your list to remove non-WhatsApp numbers and improve campaign success rates.
