Essential KYC Documents and Guidelines for Financial Services

KYC Guidelines

As per RBI guidelines, it is mandatory to complete the KYC (Know Your Customer) process before opening a bank account and operating it. The completion of the KYC safeguards banking and other financial services from being misused for unlawful activities. 

According to this process, customers must provide valid documents required for KYC, such as proof of identity (PAN card, Voter ID, Aadhaar card, or Passport) and proof of address (Rental agreement, Utility bills, or driving license). You also need to provide a recent passport-sized photograph. 

The purpose of the KYC verification process is to ensure the financial system is safe and secure. Proper verification of customers helps banks and other financial institutions protect their systems against fraud and illegal financing. Maintaining transparency from both ends builds trust between the bank and its customers.  

There are two ways to complete KYC.

Physical KYC – For a physical KYC, customers are required to submit hard copies of documents, and verification is conducted in person at the office and residence address. The applicant must show the originals for a successful verification.l 

eKYC – Also known as online KYC registration. In this process, a digital approach is adopted by utilising Aadhaar authentication on a video call with the customer, thus making it quick and paperless.

The KYC process is not just a regulatory formality, but a crucial step that ensures authenticity and safety for both the bank and the customer.

What are the steps for completing the KYC?

 The KYC process undergoes the following key stages:

  1. Customer Identification:
  • The first step of the KYC is the collection of the customer’s details and documents as proof of the identity and residence address of the customer.
  • The data is verified, and the documents are checked to be true copies as per the government records to confirm the identity.
  • A record of the customer details and documents submitted is maintained for future reference.
  • Customer Due Diligence:

Due diligence is conducted to understand the customer’s background and business activities.

Banks and financial institutions conduct verification to confirm the customer’s residence and employment details. 

  • Enhanced Due Diligence:

If a customer is classified as high-risk, a thorough investigation is conducted into the customer’s background.

This may include requesting additional documents and thoroughly analysing your sources of income and financial activities.

  1. Ongoing Monitoring:
  • It is the responsibility of the financial organisation to maintain an ongoing process to revalidate the customer’s KYC documentation.
  • To check on transactions to trace any unusual patterns that may indicate potential illegal activities or fraud.
  • While monitoring, any suspicious activity must be reported to the concerned authority, as it helps prevent fraud and money laundering.

       The difference between e-KYC and physical KYC

  • e-KYC – It is entirely digital. The verification process is done through Aadhaar OTP or biometrics. It’s quick and paperless. 
  • Physical KYC – In this, you need to visit the branch, hand over the photocopies of valid documents, and sign the forms. It is a little slower, but for specific services it’s necessary.

    The initial process of KYC involved a physical collection of KYC documents and a manual verification. With the introduction of the digital KYC processing, the e-KYC process is now being used by most financial organisations.

The manual verification of the KYC documents involved:

  • Collection of self-attested hard copies of documents from the customer.
  • A representative from the verification agency would personally visit to verify the original documents.
  • Files and records were maintained of all the documents.
