Personal data of 17,164 residents was leaked during a residence registration verification survey in Wonjong 1-dong, Bucheon. Resident registration numbers and mobile phone numbers were leaked in connection with requests from neighborhood heads (tongjang) who said face-to-face surveys were difficult, and Bucheon City became aware of it six days after the leak and belatedly retrieved the data.
