On December 1st, it was learned from the Ministry of Industry and Information Technology that the Internet account service under the "One Certificate Tongcheck" inquiry name has newly accessed 9 Internet apps, such as Toutiao, Ctrip, Pinduoduo, Eleme, iQiyi, Xiaohongshu, Dazhong Dianping, Beike House Search and Chain Home, and the available scope of Internet accounts associated with mobile phone numbers under users' own names has been expanded to 25.

It is reported that the Ministry of Industry and Information Technology has previously launched the "one-card check" service in response to some users' problems such as difficulty in inquiring and unbinding the Internet account associated with their telephone numbers. Through the government Wechat "Gongxin Weibao" of the Ministry of Industry and Information Technology, users can click the "Service" button, and select "One Certificate Check" in "Government Service" to inquire about the number of Internet accounts associated with their mobile phone numbers. The query results will be sent to the user's mobile phone in the form of SMS. If the user has any objection to the queried mobile phone card number or Internet account result, he can contact the corresponding telecom enterprise or Internet enterprise, query the detailed information, and carry out operations such as cancellation and unbinding according to the relevant strategies.
