Recently, some netizens left a message to the Ministry of Industry and Information Technology to suggest whether to consider the itinerary displayed by the communication itinerary code to be accurate to the county level.In this regard, the Ministry of Industry and Information Technology is again replyingEmphasizedue to the limitation of technical principles, it cannot be accurate to the county level.

According to the “Minister’s Mailbox” page of the official website of the Ministry of Industry and Information Technology, the netizen left a message saying, “The itinerary code is currently only displayed for prefecture-level cities, which brings inconvenience to the precision of prevention and control work in prefecture-level cities and is not conducive to people’s travel. It is strongly required that the three major operators be The base stations are grouped by districts and counties, and the CAICT will display the itinerary code to the county level.”

In this regard, the Ministry of Industry and Information Technology replied 3 days later, “During the prevention and control of the new crown pneumonia epidemic, our Ministry organized relevant units to launch the ‘communication travel card’ public welfare service to provide free mobile phone users of China Telecom, China Mobile and China Unicom. The 14-day itinerary inquiry service is one of the auxiliary tools for people to travel during the epidemic.

The ‘communication itinerary card’ analyzes the signaling data and bill data of the mobile phone, so the premise of generating the itinerary data is that the user generates these signaling and bill data in the process of using the mobile phone. The query coverage of the card: domestic can be accurate to prefectures and cities, foreign countries can be accurate to the country (region), temporarily unable to be accurate to the district and county level of various cities (including municipalities directly under the Central Government).

The Ministry of Industry and Information Technology emphasized, “On the communication big data itinerary card query page, we have stated: ‘* Indicates that there are currently medium-risk or high-risk areas in the city, and does not mean that the user has actually visited these medium and high-risk areas.’ When using the communication itinerary card While proving your personal itinerary, you can also prove your personal itinerary by using other reasonable means such as train tickets. For specific requirements, please follow the regulations of the local epidemic prevention and control management department.”

A netizen wrote on the People’s Daily Online message board in January this year, “Recent epidemics have occurred frequently, and green codes are required everywhere. ButIt can only identify the city level, not the district, let alone the specific street. It has created a hotbed for grassroots epidemic prevention. Especially in municipalities directly under the Central Government like Beijing, all Beijing itinerary cards have stars in all areas with medium risk. I hope it can be more accurate to facilitate work, life and normal travel. “

In this regard, the Ministry of Industry and Information Technology also stated in its reply at the time, “Limited by the technical principle, the current coverage of the communication itinerary card query can be accurate to prefectures and cities in China (staying for more than 4 hours), and accurate to countries (regions) abroad, temporarily. It is impossible to be accurate to the districts of various cities (including municipalities directly under the Central Government).”

According to public information, the “Communication Big Data Itinerary Card” was launched in February 2020. It is a public welfare itinerary inquiry service jointly launched by the three basic telecom companies, China Academy of Information and Communications Technology, China Telecom, China Mobile and China Unicom, under the guidance of the Ministry of Industry and Information Technology. Provide users with proof of the countries (regions) they have visited in the past 14 days and the domestic city they have stayed for more than 4 hours.
