Starting next month, information on registered sex offenders will also be available through the Ministry of the Interior and Safety's "National Secretary" service.


On September 9, the Ministry of Gender Equality and Family announced that it will begin providing sex offender information in collaboration with the Ministry of the Interior and Safety's "National Secretary" service to enable the public to access this information more quickly and conveniently.

Currently, notifications about registered sex offenders are sent annually to roughly 6.5 million households headed by adults responsible for the protection of children and adolescents under the age of 19 in the areas where sex offenders reside.


This notification service began by mail in 2011 and expanded to mobile delivery in 2020. Now, notifications about sex offenders can be accessed through electronic documents via KakaoTalk or Naver.


However, there have been ongoing cases where notification messages are mistaken for spam or phishing and are therefore not opened. As of last year, the open rate was less than half, at 49%. In response, since September of last year, the Ministry of Gender Equality and Family decided to add the widely recognized and trusted "National Secretary" service—used by 18.2 million registered members—as a new notification channel.


Kim Sungcheol, Director of Safety and Human Rights Policy at the Ministry of Gender Equality and Family, said, "We expect that by adding a popular and highly trusted channel, we can increase the delivery rate of information on sex offenders and strengthen the safety net for households protecting children and adolescents."



Meanwhile, the mobile notification service for registered sex offender information was recognized as an excellent case in the "Public Safety Enhancement" category at the "2026 Kakao Public Innovation Awards" held the previous day.
