Phone Number Verification Service:What is Phone Number Verification Service?

Last Updated:Aug 15, 2023

Phone Number Verification Service provides comprehensive processes, including verification code generation, multi-channel verification code sending, and verification code verification. It integrates security capabilities to effectively defend against attacks of invalid registrations, and provides a convenient, secure, efficient, and easy-to-use one-stop user verification service based on mobile numbers for enterprise applications.

Benefits

Easy development and access

To access the service, just complete the configuration in the console and connect to a simple API.

The service eliminates the development costs of self-managed verification services, for example, verification code generation, storage, and verification. In addition, you do not need to configure routing policies or security protection policies for each regional language. The service allows you to directly call API operations to send verification codes without the need to submit accounts such as SenderID and WhatsApp Business Account (WABA) for filing.

Improved verification success rate

Verification codes can be sent to end users by using multiple channels. For scenarios where verification codes cannot be obtained by using Short Message Service (SMS), you can select a verification method that uses the WhatsApp or voice channel to improve the verification success rate.

The optimal channel orchestration policy is selected for you based on the sending success rates and costs in different countries and regions.

Reduced verification costs

The service proactively defends against the attacks of massive voice or text messages that are sent to specified numbers by using scripts. This reduces verification costs caused by scams and fake registrations.

The service can be charged based on the number of success times or the combination of the channel and the number of verification success times. You can choose a billing method to meet your business requirements.

Description

One-stop access from multiple channels

The service provides one-stop access from multiple channels such as SMS, voice, and WhatsApp by using the unified API. You can flexibly choose a channel to ensure that messages accurately reach users. This increases the verification conversion rate.

  • WhatsApp: One-time password (OTP) information can be delivered by using WhatsApp to ensure a high delivery rate for WhatsApp users and avoid message delivery failures due to blocking by carriers.

  • SMS: Sending verification code information by using text messages is supported by all carriers. It is the most common way to reach users, and is not limited by customer terminals and usage environments.

  • Voice: Text-to-speech (TTS) supports the conversion of verification codes into voice to reach users, with rapid voice answering and fast verification guarantee.

Intelligent security protection

Built-in security protection capabilities such as blocking on risk numbers, landline number verification, and high-risk country blacklists effectively reduce the probability of international scams and frauds, and help customers avoid risks and reduce losses.

  • The service provides built-in number detection, blocking and alerting mechanisms, success rate alerting, and other security capabilities.

  • The service establishes security risk control models and built-in frequency control rules to block the numbers that are risky and that make frequent requests.

Preset templates accelerate service rollout

The filing and review of OTP templates are complete. The templates of multilingual verification messages are provided, and the content can be flexibly configured to comply with local laws and regulations. Multiple countries can be covered by using one API.

  • SMS channel: uses the unified SenderID of Alibaba Cloud to send text messages. You do not need to submit SenderID for filing. This improves access efficiency and sending quality.

  • WhatsApp channel: uses the unified WABA of Alibaba Cloud to send text messages. You do not need to submit information such as WABA for filing.

  • Voice channel: uses the public voice number pool of Alibaba Cloud to make outbound calls. You do not need to submit a specific number for filing.

Common scenarios

Phone Number Verification Service can be applied to scenarios such as registration and authentication of new users, logon authentication, two-factor authentication, password retrieval in the case of an account change, and financial transaction confirmation.
