"Texts from the Health Insurance Corporation indicate 'Confirmed Calling Number'"

To prevent text fraud, the National Health Insurance Service requested that text messages sent by the corporation be marked with a "confirmed calling number" indicating that the Internet Promotion Agency authenticated the sender.

In addition, in the case of authenticated messages sent by the Health Insurance Corporation, they are received one after another on the screen where the information from the corporation is displayed.

The corporation said it introduced the "RCS Text Service" in August to prevent the public from mistaking the texts sent by the corporation for fraud and missing important information.

However, the service is only available for Android-based smartphones, and other operating system users were asked to be careful not to press the Internet address in the impersonation text.
