What is Know Your Customer (KYC)

Know Your Customer (KYC) is the process by which cryptocurrency exchanges and other regulated financial service providers verify the identity of their users before allowing them to access financial services. KYC is a cornerstone of global anti-money laundering (AML) regulatory frameworks and is legally required for any Virtual Asset Service Provider (VASP) operating in regulated jurisdictions.

WHY EXCHANGES REQUIRE KYC

Financial regulators worldwide require VASPs to implement KYC to: prevent cryptocurrency from being used for money laundering, terrorism financing, sanctions evasion, and other financial crimes; comply with FATF (Financial Action Task Force) recommendations adopted by 200+ countries; meet local regulatory requirements FIU-IND registration in India, FinCEN registration in the US, FCA registration in the UK. Failure to implement KYC results in regulatory fines, licence revocation, and criminal liability for exchange operators.

WHAT KYC TYPICALLY REQUIRES

Tier 1 (Basic) for limited trading access: Email and phone verification, full legal name, date of birth, country of residence.
Tier 2 (Standard) for normal trading limits: Government-issued photo ID (Aadhaar, passport, driver's licence), selfie with ID (liveness check), proof of address (utility bill, bank statement dated within 3 months).
Tier 3 (Enhanced) for high-volume or institutional users: Source of funds documentation, income verification, enhanced background checks.

THE KYC PROCESS ON MAJOR EXCHANGES

Most exchanges use automated KYC platforms (Jumio, Onfido, Sumsub) that process document verification within minutes. AI-powered facial recognition compares selfies to ID photos. Manual review handles edge cases. Typical processing time: 5 minutes to 24 hours.

KYC AND PRIVACY CONCERNS

KYC creates a permanent record linking your real identity to your cryptocurrency addresses. This data is subject to exchange security practices, potential breaches, government requests, and data retention policies. Users who prioritise financial privacy use KYC-free alternatives decentralised exchanges (no KYC required), peer-to-peer trading platforms, and privacy-focused tools though these carry different risks and regulatory implications.

INDIA-SPECIFIC KYC

Indian exchanges registered with FIU-IND under PMLA must implement full KYC. Aadhaar-based eKYC (digital verification via UIDAI) is accepted on most Indian platforms, enabling near-instant verification.

Terms in addition to the Know Your Customer (KYC)

Blockchain

A blockchain is a subset of a distributed database. The Bitcoin inventors originally prototyped the system in 2008. This modern database is made up of separate blocks that are connected together in a chronological chain. Blockchains may be used to store a wide range of data types. It has mostly been utilized as a public ledger for bitcoin transactions to date. A peer-to-peer network comprised of independent nodes uses a consensus process to ensure the blockchain's security and legitimacy. Each node in the network keeps a public and immutable copy of the data.

2 Factor Authentication (2FA)

2 Factor Authentication is a security measure with two layers. It is used by the majority of cryptocurrency exchanges. To log in, you must provide not only a password, but also a code obtained, for example, from the Google authenticator.

Airdrop

An airdrop is a method of distributing coins. End users can typically obtain coins for free or in exchange for doing a small task, such as subscribing to a newsletter, sending a tweet, or inviting others via a personal affiliate link. Cryptocurrency airdrops — the act of depositing cryptocurrency into public crypto wallets — are utilized as a marketing, liquidity creation, and network bootstrapping technique for many different types of blockchain initiatives.

Altcoin

Altcoin - "alternative coin" - is any kind of digital currency other than Bitcoin. Since the launch of Bitcoin, the world's first digital currency, many altcoins (as well as supporting blockchains) have been created. Altcoin digital currencies share many similarities to Bitcoin, but consistently and have significant differences. There are about 20,000 altcoins, and this number is expected to grow significantly in the coming years. Altcoins often develop Bitcoin features. Ethereum, currently the most widely used blockchain, supports digital contracts and separate applications where Bitcoin does not. Altcoins are also often created to cater to the needs of different users. The Litecoin blockchain, for example, can process payments quarterly for the duration of Bitcoin.

Cold Storage

Cold storage is the way to store cryptocurrency offline. The word refers to the use of offline wallets that are not connected to the internet. Cold storage is the most secure way to keep cryptocurrencies since an offline currency becomes less likely to be hacked and stolen. Paper wallets, printed renditions of private keys, and offline hardware and software wallets are all examples of cold storage.
