Companies can utilize a phone number verification and SMS service to verify the number of their customers and other users. It can help reduce the possibility of fraud and make sure that messages are delivered to their intended recipient. The service is based on SMSing a code that the user must enter in the online or application questionnaire. This verifies that the user is in possession of the mobile phone that is associated with the number provided and can stop fake accounts and illegal activity. Twilio is a common provider of SMS and phone number verification.
