  • It determines the line type of phone number, such as mobile, landline, Voice over Internet Protocol (VoIP), or toll-free. This helps understand the type of the number and its intended use.
  • The phone validator checks the phone number against carrier databases to determine the service provider associated with the number. This can also help in determining if the number is active and in use.
  • Some tools also identify the location information associated with a phone number. This typically includes country, region, and city. This data can help verify if the number is correct for the specified location.
  • Some tools also support bulk phone number validation.
