Global Phone Verification validates that a phone number is callable and identifies its type: landline; VoIP; or mobile; offers carrier details, and then determines the country of origin.
The Premium Phone Verification feature determines whether a mobile number is live and connected. This is an ideal service to keep your mobile database clean and updated, and helps reduce wasting money on SMS text that will never reach due to wrong or invalid numbers. Ideal for call centers, list owners, and websites that collect mobile numbers in real-time. Premium Phone supports 25 countries, including Canada, Germany, United Kingdom, Mexico, Spain, India, Japan, Korea, and more.
