Mobile Number Verification Online

For companies deploying SMS sending campaigns or reservation websites, Mobile number verification online is essential to keep inactive numbers off of their lists and ensure that they are only communicating with real customers. This is especially true for businesses that need to verify the identity of a user, such as when using 2-factor authentication. In such cases, a one-time pin code is sent to the user’s phone number via SMS or RCS (or even over chat apps like WhatsApp or Viber). By requiring the user to enter this OTP, the business can be sure that they are communicating with a genuine user and their device is in their possession.
