## What the LEI Verification API does

LEI Verification validates a Legal Entity Identifier code and returns the registered details of the entity behind it.

The Reserve Bank of India requires an LEI for large-value transactions by non-individual entities. Verifying it at onboarding avoids discovering a missing or lapsed identifier at the moment a payment needs to move.

## Where teams use the LEI Verification API

1.  Verifying corporate counterparties before large-value transactions
    
2.  Meeting RBI LEI requirements in payment flows
    
3.  Confirming entity details in cross-border trade
    
4.  Screening corporate clients during onboarding
    

## Frequently Asked Questions (FAQs)

Which entities need an LEI?

Non-individual entities conducting large-value transactions, under thresholds set by the RBI. Requirements have widened over time, so check the current position.

Do LEIs expire?

They require annual renewal. A lapsed LEI can block transactions, so status matters as much as existence.

Is an LEI the same as a CIN?

No. A CIN is the Indian company registry identifier; an LEI is a global identifier used for financial transactions.
