Phone Standardization


A validated list of international phone numbers is essential when you need to connect with your customers. With Global-Z’s Phone Number Validation solution you can validate and standardize your phone numbers internationally. Our phone number services will parse, validate and format your phone numbers accurately based on country-specific rules. Our solutions will help you:

  • Improve matching
  • Improve the productivity of your telemarketing campaigns
  • Identify inaccurate phone numbers
  • Improve your ability to analyze phone data down to a specific geographic area
  • Increase ROI

How it Works

Our phone standardization/validation solution tests your phone numbers against international phone datasets that we license. By utilizing these datasets we are able to append geographic, carrier and additional information to your international phone numbers.

The additional validation information is provided as a score, which provides the following insight into your international phone numbers:

  • Valid vs. Invalid
  • Whether the phone number was parsed successfully
  • Identify if the phone numbers are located in the country as identified
  • Determine the carrier type of the number, cell, fax, land-line, etc. (Supported countries for this service are listed below)
