One Nation : One KYC

A Ready Blueprint for 'One Nation One KYC' — The Unified Citizen Profile (UCP)

================================================

Respected Smt. Nirmala Sitharamanji,

Namaskar.

I write to you as a 92-year-old citizen and a lifelong observer of India's policy

landscape, with a sense of quiet satisfaction — and some urgency.

Your recent call at the SEBI event for a 'One Nation One KYC' system (covered by the Times of India on 25 April 2026) :

need-of-the-hour-nirmala-sitharaman/articleshow/130522833.cms) 

resonates deeply with a framework I have been advocating since 2020.

 

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

MY EARLIER PROPOSALS — A BRIEF HISTORY

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

▸ SUIIC — Secure Unified Instant Identity Card (2020)

  Proposed a single Aadhaar-anchored digital identity capsule, verifiable offline and

  online.

▸ YUP — Your Unified Profile (2020)

  Blog: https://myblogepage.blogspot.com/2020/01/i-am-one-i-will-become-many.html

  Argued that a citizen's identity should be verified once and reused everywhere —

 for SIM cards, bank accounts, college admissions, and government schemes alike.

▸ UCP — Unified Citizen Profile (2025)

  Blog: https://myblogepage.blogspot.com/2025/10/unique-citizen-profile.html

  A fully detailed framework for a consent-based, Aadhaar-linked digital profile,

 accessible by banks, insurers, mutual funds, FinTechs, and government

 departments via a standardised API.

▸ AVC — Aadhaar Verification Capsule (2025)

  Blog: https://myblogepage.blogspot.com/2025/12/avc-ucp-yup.html

  Proposed leveraging UIDAI's new verification measures to create a portable,

 citizen-controlled identity bundle.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

WHY UCP IS THE ANSWER TO 'ONE NATION ONE KYC'

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

The UCP rests on five pillars that directly address what you have called for:

1. VERIFY ONCE — 

The citizen completes a full biometric KYC once, via Aadhaar OTP + face-match.

 This creates and populates their UCP record in the Central KYC Registry (CKYCR).

2. STORE IN A STANDARD SCHEMA — 

Name, DOB, address, PAN, income, mobile, email — all verified, digitally signed by

 the issuing authority, and held in a structured profile.

3. CONSENT-BASED SHARING — 

Any institution (bank, insurer, FinTech, mutual fund, government portal) calls the

 CKYCR API. The citizen receives a mobile prompt: one tap to approve. No forms.

 No branch visits. No repeated selfies.

4. INSTITUTION RECEIVES A LEGALLY VALID KYC BUNDLE — 

Digitally signed, regulator-compliant. RBI, SEBI, IRDAI, and PFRDA regulated

 entities all draw from the same single source of truth.

5. AUTO-REFRESH — 

When a citizen updates their address (Post Office, municipality), the UCP

 propagates the change to all linked institutions automatically. No re-KYC.

Critically, all the infrastructure required already exists in India: Aadhaar, CKYCR,

 DigiLocker, the Account Aggregator framework, and eSign. The UCP is the

governance and schema layer that ties them together.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

A HUMBLE REQUEST

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

I would respectfully request that the Department of Financial Services and UIDAI

 consider examining the UCP framework as a ready blueprint — not a concept to

 be invented from scratch, but an architecture that has already been thought

 through in detail.

If it would be of any use, I am available for any discussion or submission of a

 detailed technical note.

With respectful regards and best wishes for this important initiative,

Hemen Parekh
