The Ministry of Industry and Information Technology approved ten firms to pilot
number-protection services and allocated 700-prefix dedicated numbering
resources. The service, commissioned by platforms such as food-delivery and
ride-hailing apps, assigns temporary 15-digit numbers beginning with 700 to
users in place of their real mobile numbers to reduce number-leakage risk. When
users opt in at order placement, contact between users and delivery riders or
ride-hailing drivers is routed via the 15-digit 700 numbers; neither party’s
real mobile number is displayed.
