The workflow
From phone list to useful results
Upload your list
Choose your CSV or Excel file as it is and pick the phone column from a preview. No need to trim it to one column first.
Choose your check
Check line type and fake numbers, or fake numbers only, and choose which countries to check. You’ll see your exact total, including any volume discount, before you pay.
Pay and download
Pay by card or invoice. We email you a download link when your results are ready. Most lists finish in under 30 minutes.
Clean up your list before your next campaign
Working with purchased leads, an old CRM export or a call-center list? Find the fake and invalid numbers, and see which are cell phones, landlines or VoIP, before your team spends time dialing.
Your results have one row for every row you uploaded, in the same order, so you can paste them right beside your list. See how to prepare your file and use the results.
Want to check new leads as they come in instead? See phone validation for leads.
Results describe the number, not the person. They don’t confirm who owns it, whether a call or text will get through, or whether you have permission to contact someone.
