# Why were an SMS and email sent by CDSL informing about the blocking mechanism for payin of securities?

> You received these notifications because CDSL validates depository transfer instructions with Clearing Corporation (CC) obligation details as per SEBI…

## Short answer

You received these notifications because CDSL validates depository transfer instructions with Clearing Corporation (CC) obligation details as per SEBI guidelines.

## How the validation works

CDSL validates transfer instructions against CC obligations (the shares you must deliver for your sell orders). If the details match, your transaction goes through. If they don't match, CDSL rejects the transfer.

You don't need to take any action. iRage ensures that all CC obligation details match for your securities to transfer successfully, including:

Unique Client Code (UCC)

Trading Member (TM) ID

Clearing Member (CM) ID

Exchange ID

ISIN

Quantity

Settlement details
