# Third Party Validation (TPV)




## **What is TPV?** 



KYC is mandatory while registering on Demat Account to trade in equity and purchase mutual funds.The Know Your Customer (KYC) process helps against money laundering and prevents the financing of terrorist activities. Therefore the transactions can go through for a user only through the verified account.

Attempts from any other account will be rejected by banks ,gateways or PSPs in case of UPI. This process is called Third Party Validation(TPV).

> **Note**
> 1. Currently only UPI and Net Banking support TPV in the industry
> 2. Mandate Recurring Flow doesn’t need any TPV details to be passed. Only while Mandate Registration these details are required.
