About Phone Validator
Phone Number Validation for Better Contact Data
Phone Validator helps businesses, apps, and marketing agencies understand the numbers in their contact lists. Check line type, service provider, and number origin before deciding how to reach someone.
What a lookup tells you
Results identify the current line type, including cell phone, landline, VoIP, toll-free, or invalid/fake. They also include the current service provider and a city and state based on the number's area code and prefix.
Coverage includes phone numbers in the United States, Canada, and more than 250 countries. Canadian number details have a portability limitation, explained below.
