VALIDATE BY LRN

The Validate By LRN API provides a simple and efficient method for determining whether the ANI Type received during call setup is consistent with the known carrier and numbering characteristics of the calling telephone number.

Customers submit the calling telephone number (ANI) and the ANI II value received during call setup. The API analyzes the ANI II classification against authoritative telecom intelligence sources, including current routing and numbering information associated with that telephone number.

Rather than returning multiple data elements for customer analysis, the Validate By ANI API performs the comparison and returns a simple validation result, 0 OR 1.

Validation Logic

The service evaluates whether the reported ANI Type is CONSISTENT with the service characteristics indicated by carrier routing and numbering data sources.

The API response contains a single validation code:

• Validation Code 0 – The ANI Type is consistent with the carrier and numbering      information associated with the telephone number.

• Validation Code 1 – The ANI Type cannot be verified or is not consistent with the carrier and numbering information associated with the telephone number.

IMPORTANT  

The VALIDATE BY LRN API does not determine whether a call is fraudulent, spoofed, or malicious. Instead, it provides an independent consistency assessment based on authoritative telecom data sources, enabling customers to incorporate the result into their own routing, authentication, analytics, and risk-management processes.  The consistency assessment is to be used as a risk indicator, not a source of truth.
