The workflow

From phone list to useful results

  1. 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.

  2. Choose your countries

    Choose which countries to check. You’ll see your exact total, including any volume discount, before you pay.

  3. Pay and download

    Pay by card or invoice. We email you a download link when your results are ready. Most lists finish in a few 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.

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.

1 Includes current carrier and porting data where available, to identify numbers whose line type or carrier has changed (such as landline to cell). Porting data is not available for Canadian numbers.

2 Most lists finish in minutes; 100,000 records finish in under 10 minutes.

PORTED NUMBERS: Ported numbers are phone numbers that have been switched between phone companies (so the holder keeps the same number) or numbers that have been switched from one line type (like landline) to another (like cell).

TCPA and Do Not Call: a line type result is not consent to call or text, and we don't provide Do Not Call scrubbing or legal advice. Ask your attorney whether your calls and messages comply with the TCPA, Do Not Call rules and state telemarketing laws.
