Ensure You Have Valid, Callable Domestic and International Phone Numbers

With only a phone number and/or a country entered, Melissa Global Phone can determine whether the phone number is valid for the region and identify the country of origin from the international access code. The solution also easily verifies phone number types (US/CA Only) such as landline, VoIP, or mobile, as well as carrier. We even establish the most common language in use for the area.

  • Verify and correct numbers at point of entry to ensure only accurate information enters your database
  • Ensure phone numbers are live before you call to save time and resources
  • Identify the dominant language in the number's region to establish better customer relationships by improving communication

How Phone Verification Works

Phone Verification - Premium Phone Verification - United Kingdom

Premium Phone Verification

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 texting services that will never reach due to wrong or invalid numbers. Ideal for call centres, list owners, and websites that collect mobile numbers in real-time. Premium Phone supports 25 countries, including the U.S., Canada, Germany, United Kingdom, Mexico, Spain, India, Japan, Korea, and more.

CallerID Data

CallerID taps into real-time carrier data to return the name of the person or business associated with the number at activation. The feature helps you provide more personalised and relevant messages to customers for greater marketing effectiveness.
