Technical Framework
Our platform is built as a cloud native API first system designed for enterprise scale operations. Core components include number provisioning routing and telecommunication interconnects message composition and telemetry for observability. The architecture is designed to minimize data exposure while maximizing OTP deliverability and privacy.
Number Provisioning and Routing
Numbers are provisioned from carrier grade pools that are curated for quality with geographic distribution to optimize deliverability. For verification messages the system uses dedicated OTP channels with configurable TTL values. The routing engine selects optimal paths based on carrier latency historical deliverability and regulatory compliance. In addition we support China local or international routing depending on your regulatory needs and customer base.
API and Integration
Developers interact with our service via RESTful APIs and Webhooks. Typical flows include:
- OTP generation: POST /v1/otp/send with phone number locale and purpose. The request returns a transaction ID and a status.
- Delivery tracking: Webhook callbacks or GET endpoints to confirm delivery success pending or failure with detailed status codes and timestamps.
- Verification validation: POST /v1/otp/verify to confirm that a provided code matches the OTP sent.
- Number management: endpoints to acquire rotate or retire number pools with per region controls.
We also provide and maintain documentation sample code and sandbox environments to accelerate integration including examples in common languages and frameworks. The API design emphasizes idempotency security and rate limiting to ensure predictable behavior in high volume environments.
Security Privacy and Data Handling
Security is embedded into every layer TLS 1.2 or higher for in flight data AES 256 encryption at rest and strict access controls. Logs are minimized and can be configured to exclude message content preserving confidentiality while enabling troubleshooting and auditability. Data residency options let you choose where data is stored or processed which is particularly important for sensitive deployments and for meeting regional regulatory requirements.
China-Specific Considerations
China presents unique regulatory and network considerations. Our solution supports compliant routing to major Chinese operators where permissible with options for domestic routing to reduce latency and improve delivery reliability. If your business requires domestic numbers we offer region appropriate provisioning that aligns with telecom governance and data protection standards applicable within China.
Confidential Use of Online Services
Confidentiality is more than a policy its a core architectural principle. We minimize the exposure of message content and subscriber data in logs use ephemeral identifiers for verification transactions and provide controls to prevent data leakage across teams. Enterprises can enforce strict data governance through role based access audit trails and configurable data retention windows. For customers handling sensitive operations financial services healthcare or regulated industries our platform integrates with existing security ecosystems and supports NDA compliant data handling arrangements.
How It Works in Practice
Implementing confidential SMS verification is straightforward when you follow a few well defined steps. The workflow is designed to be translation ready for multi country deployments including the tricky case of mass onboarding in China. Here is a typical lifecycle:
- Account setup Create an enterprise account define data residency preferences and establish API credentials with role based access control.
- Pool selection Choose primary and backup number pools part of the double list based on geography language and compliance needs.
- OTP generation Initiate a verification request via the API specifying the target phone number and the code parameters length TTL and retry policy.
- Message delivery The system routes the OTP through the most suitable pool with fallback logic to the backup pool in case of delays or failures.
- Delivery confirmation Receive real time status via webhook or polling enabling your system to confirm success or trigger retry logic or escalation.
- Verification check If your flow requires server side validation confirm that the provided code matches the OTP sent within its TTL.
- Data governance Apply retention and deletion policies and access controls ensuring that only authorized personnel can view sensitive data.
Double List Redundancy and Reliability
The double list concept is a structured approach to ensure reliability and resiliency. It means maintaining two independent pools of numbers primary and secondary and a routing layer that automatically switches between them in the event of degradation. This redundancy reduces the risk of service outages caused by carrier problems regulatory changes or regional outages. In practice the system can perform live monitoring of pool health perform automatic failover and then notify operators of any changes in routing. For enterprises with large verification volumes the double list model is a fundamental reliability guarantee that keeps your user onboarding flows smooth and uninterrupted.
