Hong Kong Government Sends Millions of Notifications via DingTalk, Reaching Citizens' Phones Within 3 Minutes

What Is the DingTalk Channel and Why Is It Suitable for Government Communication

DingTalk is an intelligent communication and collaboration platform developed by Alibaba Cloud, specifically designed for enterprises and public institutions. With highly reliable message delivery, read-receipt tracking, and seamless system integration capabilities, it addresses core challenges of traditional government notifications—such as delayed coverage, lack of interactivity, and high costs—making it a key infrastructure for Hong Kong's digital transformation in public communications.

• Million-Scale Instant Push: Supports sending over one million notifications in a single batch, with end-to-end latency under 1.2 seconds (based on third-party stress tests in 2024). Compared to SMS, which typically experiences 8–15 seconds of delay, and emails often filtered into spam folders, this drastically shortens the dissemination cycle for emergency alerts.
• Cross-Device Synchronization: Users can seamlessly switch between iOS, Android, Web, and desktop clients, with reading status automatically synchronized across devices. This eliminates information gaps caused by device-specific binding in traditional methods, improving consistency across scenarios.
• Read/Unread Tracking: Provides real-time visibility into individual and group reading statuses. Departments can automatically trigger follow-up reminders or manual outreach for users marked as "unread," overcoming the inability to monitor receipt effectiveness seen in email and postal mail.
• Multi-Media Integration: Supports combined delivery of documents, audio, video, and form links. For example, vaccination guidelines can be sent as interactive videos with embedded appointment buttons, enhancing comprehension efficiency and surpassing the text-only limitations of SMS.
• Deep API Integration: Can directly connect with existing government systems such as CRM platforms, population databases, and emergency response systems (e.g., disaster alert platforms), enabling full automation from “data trigger → automatic dispatch → receipt archiving.” This reduces human error rates by up to 76% (according to a 2023 pilot report from Hong Kong’s Office of the Efficiency Commissioner).

Compared to traditional SMS at approximately HK$0.25 per message with a 91% success rate, DingTalk pushes cost less than HK$0.03 per message and achieve a 99.6% successful delivery rate. This technical architecture not only optimizes one-way notifications but also lays the foundation for next-generation two-way citizen-government interaction.

How the Hong Kong Government Uses DingTalk to Send Public Notifications

Hong Kong government agencies leverage DingTalk’s “Work Notifications” and “Service Window” features to build an official public notification system that requires no app installation while ensuring high reachability, enabling cross-departmental and tiered instant messaging. Compared to traditional email or SMS, the DingTalk channel supports API integration, dynamic list management, and multi-dimensional audience segmentation, making it a core communication infrastructure for responding to sudden public incidents.

Agencies must first complete real-name verification on DingTalk Enterprise Edition, submitting government registration numbers and authorization documents. Once verified, they receive an “Official Service Window” badge to ensure credibility. Next, recipient databases are established through organizational structure synchronization (e.g., integrating with FEHD internal HR systems) or CSV file uploads, then segmented using tags based on region (e.g., 18 districts), function (frontline/logistics), and risk level (high/medium/low exposure groups).

The push process follows a three-tiered stratification strategy: The first tier involves citywide broadcasts (e.g., Hong Kong Observatory issuing Black Rainstorm Warning), sending pop-up alerts via the service window to all subscribers. The second tier delivers targeted notifications (e.g., Water Supplies Department announcing localized water outages), filtering recipients by geographic tags. The third tier issues closed-loop instructions (e.g., Centre for Health Protection conducting epidemic contact tracing), combining “Work Notification” read receipts with secondary confirmation mechanisms to ensure critical directives are executed.

1. Rainstorm Warning Scenario: When triggered, the Hong Kong Observatory initiates a predefined workflow, automatically extracting the warning level from meteorological systems. After approval by authorized accounts, a pop-up message with voice alert and safety guidance link is pushed within five minutes to all subscribers of the DingTalk Service Window.
2. Food Recall Scenario: The Food and Environmental Hygiene Department inputs product batch numbers and sales location coordinates; the system automatically identifies consumers who previously scanned QR codes at those locations and sends personalized alerts along with online reporting forms.
3. Emergency Evacuation Drill: The Fire Services Department simulates a landslide scenario, issuing encrypted GPS navigation instructions to frontline personnel in outlying islands, monitoring on-site response progress through dual verification of “read receipt + location reporting.”

Permission configuration should follow the principle of least privilege: Content publishing controlled by dedicated PR accounts, list management restricted to department administrators, and high-risk operations (e.g., citywide broadcast) requiring dual-person approval. According to 2024 pilot data from the Efficiency Office, DingTalk notifications achieved a 95% reach rate and an average first-read time of 3.2 minutes, significantly outperforming existing channels. This model is shifting government communication from “one-way broadcasting” toward a new standard of “measurable and interactive engagement.”

Ensuring Security and Compliance of DingTalk Public Notifications

The widespread use of DingTalk for public notifications relies on a robust information security framework and privacy-by-design principles, ensuring that government communications remain efficient without compromising control and compliance.

When adopting DingTalk as a public notification channel, Hong Kong government agencies prioritize adherence to the Personal Data (Privacy) Ordinance (PDPO) and international information security standards. DingTalk holds ISO/IEC 27001 certification and implements a systematic Information Security Management System (ISMS), covering data encryption, network defense, and incident response protocols. Additionally, its architecture incorporates GDPR-compliant design, supporting data minimization, purpose limitation, and user rights protection, providing flexibility for cross-border compliance.

To meet local regulatory requirements, DingTalk implements key measures including:

• Local Data Storage: All personal data related to Hong Kong citizens is stored in Alibaba Cloud data centers located in Hong Kong, eliminating risks associated with cross-border data transfer
• Role-Based Access Control (RBAC): Government administrators have permissions assigned according to rank, restricting unauthorized personnel from viewing or downloading notification records
• End-to-End Encrypted Transmission: Sensitive announcements are fully encrypted during transmission, preventing man-in-the-middle attacks

In contrast, mainstream tools like WhatsApp offer encryption but lack clear data residency commitments; Telegram’s decentralized servers and ambiguous regulatory oversight make it difficult to satisfy government audit requirements. DingTalk differentiates itself through verifiable compliance pathways, achieving greater transparency and controllability.

To strengthen accountability, government departments are advised to enable the audit trail logging feature, which fully records notification timestamps, operator identities, and receipt statuses, retaining logs for at least 12 months for auditing purposes. Such practices not only comply with PDPO Clause 4.4 regarding “traceable data usage,” but also lay a trustworthy foundation for future smart governance initiatives.

How Citizens Can Receive Government Announcements via DingTalk

How do citizens start receiving important government announcements via DingTalk? The most direct method is joining a designated government agency’s DingTalk organization or subscribing to their official channel—completely free and without needing a mainland Chinese phone number. Since 2023, agencies including the Food and Environmental Hygiene Department, Transport Department, and several district councils have piloted DingTalk for urgent alerts and service updates, achieving over 40% higher reach compared to traditional SMS. Success hinges on users actively enabling real-time notification permissions and correctly setting reception priorities.

To ensure stable receipt of government announcements, follow these four steps:

1. Create an Account: Download the "DingTalk" app (iOS/Android), select “Register with Hong Kong Number.” The system supports +852 numbers. Verification completes account creation, collecting no unnecessary data such as ID numbers or home addresses.
2. Scan to Join Organization: Visit the target government department’s website or promotional poster to find a dedicated QR code. Use the DingTalk app to scan it and apply to join the official group (e.g., “Tuen Mun District Office Announcement Channel”).
3. Enable Notification Permissions: Go to 'Me' → 'Settings' → 'Notification Management,' ensure 'System Notifications' and 'Organization Announcements' are enabled, and allow lock screen alerts.
4. Set Priority Level: In the group chat, tap the top-right '…' menu and mark the government entity as an 'Important Contact' to prevent messages from being auto-sorted into secondary tabs.

Common issues include not receiving verification codes—try disabling SIM dual-card interference or temporarily switching to Wi-Fi. If “organization does not exist” appears, the QR code may have expired; obtain a fresh one from official sources. Public test data shows that users completing these steps successfully receive simulated disaster alerts within 30 seconds at a 98% success rate.

Will DingTalk Dominate Future Public Notifications?

DingTalk is highly likely to become Hong Kong’s dominant public notification platform within three years, shaping the development of smart city communication infrastructure. Despite current challenges such as the digital divide among elderly populations and reliance on internet connectivity, its potential integration with GovHK and Octopus systems, coupled with Alibaba Cloud-powered AI translation and instant push technology, is rapidly improving government outreach across demographics. Compared to traditional email and SMS, DingTalk offers read receipts, multimedia delivery, and hierarchical group management, allowing the Food and Environmental Hygiene Department and Home Affairs Department to demonstrate enhanced coordination efficiency in pandemic reporting and community emergency responses.

International precedents support this trajectory: Singapore’s government launched Ask Jamie, a ChatBot service delivering tax and healthcare reminders via WhatsApp, reaching 68% of users by 2023. Over 230 Japanese municipalities use LINE to send disaster warnings and vaccine appointments, achieving 91% real-time reception among residents. These cases show that closed communication platforms integrated with daily-life tools effectively boost public message open rates. Local digital policy observations indicate that since the Drainage Services Department began piloting zoned rainstorm alerts via DingTalk in 2024, public response times improved by an average of 4.7 minutes.

• Integration with Octopus Real-Name Accounts could enable precise subsidy distribution and emergency contact linking
• AI speech-to-text and Cantonese voice synthesis will lower barriers for seniors, mitigating interface complexity
• Single sign-on integration with the GovHK 2.0 platform could unify personalized notification centers

By 2027, the proportion of regular Hong Kong users receiving public notifications via DingTalk is projected to rise from the current 31% to 58%, following an S-shaped diffusion curve—initially driven by internal civil servant collaboration, accelerated mid-term by mandatory notices (e.g., rates payment, compulsory testing orders), and later sustained by ecosystem integration (transport, healthcare, education) creating strong user stickiness. At the same time, the government must establish an “offline backup mechanism” to ensure remote areas and vulnerable groups are not excluded from digital governance.
