Real numbers onlyBy asking your customer to provide a phone number — and then validating the legitimacy of that number — you can minimize fraud while ensuring that you have a way to contact that customer in the future.
The right channelValidating information enables you to distinguish mobile from landline numbers — ensuring that you don’t try to send text messages to landlines if reaching out via SMS.
Clean databaseBy periodically validating the numbers in your customer database, you can be sure that customer numbers are still reachable, reducing delivery errors when running SMS or voice-based marketing campaigns.

How phone number validation works
1. Identify a phone number to validate
Your app can ask users to enter a phone number during registration or you can identify existing numbers in your customer database.
2. Query Vonage APIs Number Insight
Your application passes the phone number to Number Insight API for analysis.
3. Gather insight
Vonage APIs Number Insight queries multiple information sources to validate and gather information about the number.
4. Act on validated information
Vonage APIs Number Insight returns information on the phone number to your application so you can remove unreachable numbers and identify valid numbers as mobile or landline.
