MNRL

MNRL API Category

Overview

The Mobile Number Revocation List (MNRL) API category provides a secure and efficient way to verify whether mobile numbers have been permanently disconnected. Published monthly by the Telecom Regulatory Authority of India (TRAI), this list serves as a critical resource for organizations to validate mobile numbers before engaging in communications or transactions. By integrating MNRL verification into your systems, you can significantly reduce fraud risks, enhance communication security, and ensure compliance with telecom regulations.

Category Details

APIs in this category: MNRL Check

Key Capabilities

Main Functionality

The MNRL API category enables organizations to query the official TRAI database of permanently disconnected mobile numbers, providing real-time verification to prevent fraud, improve data quality, and ensure communication efficiency.

Mobile Number Verification

Quickly verify if a mobile number has been permanently disconnected by checking against the official TRAI MNRL database, helping prevent fraud and ensuring communication security.

Batch Processing

Process multiple mobile numbers in a single request, allowing for efficient verification of large customer databases and streamlining verification workflows.

Regulatory Compliance

Ensure compliance with TRAI regulations by integrating official MNRL data into your verification processes, reducing the risk of regulatory penalties and improving overall data governance.

Common Use Cases

Financial Services

Telecommunications

E-commerce

Verify mobile numbers during customer onboarding to prevent fraud

Validate contact information before processing high-value transactions

Clean customer databases to remove permanently disconnected numbers

Integration Considerations

Best Practices

Implement caching mechanisms to reduce redundant API calls for frequently checked numbers

Schedule regular batch verifications to keep your customer database updated

Include MNRL verification as part of your customer onboarding workflow

Consider implementing fallback verification methods for edge cases

Important Limitations

The MNRL is updated monthly by TRAI, so there may be a delay between when a number is disconnected and when it appears in the list

The API only verifies if a number is permanently disconnected, not temporarily suspended

Verification is limited to Indian mobile numbers under TRAI's jurisdiction

Rate limits may apply to prevent abuse of the service

How APIs in this Category Work Together

The MNRL category currently contains a single API endpoint (MNRL Check) that serves as the foundation for mobile number verification. This streamlined approach ensures simplicity and efficiency in implementation while providing comprehensive verification capabilities.

Key Integration Patterns:

MNRL Check + Your CRM System: Integrate MNRL verification directly into your customer relationship management system to automatically flag potentially invalid mobile numbers

MNRL Check + Onboarding Workflows: Incorporate verification checks during customer registration to prevent fraud at the entry point

MNRL Check + Batch Processing Systems: Schedule regular database cleanups by processing your entire customer database against the MNRL

The MNRL Check API can be integrated at multiple touchpoints in your business processes. For example, a financial institution might verify a mobile number during account creation, before processing a high-value transaction, and periodically as part of database maintenance—creating a comprehensive verification strategy that minimizes fraud risks throughout the customer lifecycle.

The MNRL API category complements other verification and security-focused API categories in a comprehensive identity and communication validation strategy. By combining MNRL checks with other verification methods, organizations can create robust multi-layered security protocols.

Related Categories include:

KYC Verification: Complements MNRL by providing additional identity verification, creating a more comprehensive customer validation process

OTP Services: Works alongside MNRL to ensure one-time passwords are sent only to valid, active mobile numbers

Fraud Detection: Enhances fraud prevention capabilities by adding mobile number validation as an additional security layer

When implemented together, these categories create a robust verification ecosystem. For example, a financial institution might first check if a customer's mobile number is valid using MNRL, then proceed with OTP verification, and finally complete KYC processes—creating multiple layers of security while ensuring a smooth customer experience for legitimate users.
