Core Viewpoint - The Ministry of Industry and Information Technology (MIIT) has initiated a pilot program for number protection services to reduce the risk of personal information leakage, particularly in sectors like express delivery, food delivery, and ride-hailing [1][15]. Summary by Sections Number Protection Service - Number protection service involves assigning temporary numbers (referred to as "intermediate numbers" or "privacy numbers") to users, allowing them to communicate without revealing their real phone numbers [2][3]. Application in Various Services - In ride-hailing, drivers and passengers communicate through a temporary number assigned by the platform, keeping their actual phone numbers hidden [4]. - In e-commerce, platforms generate a temporary number to conceal the actual phone number of the recipient during order fulfillment and delivery [5]. - For food delivery, a temporary number is created to hide the consumer's phone number from merchants and delivery personnel [6]. Challenges Encountered - Initial implementations faced issues such as inconsistent formats for intermediate numbers, leading to user confusion about whether they were receiving calls from a temporary or actual number [7]. - Some companies misused the service by using real phone numbers as intermediate numbers for marketing calls or even fraudulent activities [8]. Introduction of 700 Numbers - The MIIT has designated the 700 number as a dedicated code for number protection services, which is distinct in length and format, making it easier for users to identify [9][10]. - The 700 number system is designed to meet the future demand for billions of code resources in sectors like express delivery and ride-hailing [11]. User Experience and Communication - Users can opt-in for number protection services when using internet platforms, and calls made using the 700 number will not reveal the user's actual number [12][13]. - The communication process remains unaffected, as both parties will see the intermediate number during calls and messages [13]. Pilot Program Timeline - The pilot program consists of three phases: a three-month preparation phase, a three-month transition phase, and a two-year formal pilot phase, after which the 700 number will be fully utilized for number protection services [14]. - The 700 number is prohibited from being used for commercial marketing calls or messages, with strict management and monitoring by the MIIT to prevent misuse [14]. Conclusion - The introduction of the 700 number is expected to enhance user experience by providing convenient services while better protecting personal phone number information and reducing the risk of information leakage [15].
