How do I know if a number is VoIP?
For US and Canada numbers, look up the carrier at Phone Validator API to Check Numbers & Look Up Carriers. If it’s a mobile carrier e.g. Cellco Partnership a.k.a. Verizon Wireless, the number is mobile, not VoIP. For a traditional landline carrier e.g. AT&T, it’s a landline, not VoIP. For a cable company e.g. Comcast, it’s VoIP but not ‘nomadic’ (it is associated with a physical address). That leaves the CLECs, Bandwidth.com, Level3, etc.
How can I check if a phone number is real?
If you need to check if a phone number is real right now, use the Real Phone Validation.
If you’re here, you understand that people give out fake phone numbers all the time. And, customers give fake phone numbers to businesses all the time.
People want to get free stuff. But, they don’t want to get marketing calls. So, they use a fake phone number on the lead form. This happens more often than you might think.
Real Phone Validation API allows users to identify disconnected and invalid numbers.
