TLDR:
Know Your Customer (KYC) refers to the procedures financial institutions and other regulated businesses use to verify customer identities and assess risk profile before establishing business relationships. KYC is a foundational element of AML compliance, sanctions compliance, and counter-terrorist financing programs, with specific obligations defined by regulators across jurisdictions.
Standard KYC Requirements
Typical individual KYC includes: full legal name, date of birth, government-issued photo ID verification (passport, national ID), address verification (utility bill, bank statement), tax identification number, employment and source of funds information, and increasingly biometric verification (selfie comparison to ID photo). For legal entities, KYC extends to: corporate documents (certificate of incorporation, articles, good standing), legal entity identifier (LEI) where applicable, beneficial ownership identification (UBO), directors and officers identification, business purpose and source of funds, and sanctions and adverse media screening on all named parties.
KYC Technology and Platforms
Specialized KYC platforms have transformed customer onboarding: identity verification providers (Onfido, Jumio, Trulioo, Veriff, ID.me), document verification using optical character recognition and AI-based authenticity detection, biometric matching (face match to ID photo), liveness detection (preventing photo or deepfake spoofing), and ongoing screening services. Cost ranges from $1-5 per KYC verification at scale to higher costs for enhanced due diligence. Modern KYC is faster (often completed in 60-120 seconds) and more accurate than traditional manual review.
Friction and User Experience Trade-Offs
KYC introduces meaningful friction in customer onboarding—abandonment rates 20-40% are common in financial services applications. Successful businesses optimize KYC: progressive disclosure (collecting minimum information initially, more for higher transaction tiers), document upload UX (clear instructions, immediate feedback), retry mechanisms for OCR failures, alternative verification paths for users without standard documents, and clear communication about why information is needed. Risk-based KYC (lower friction for lower-risk customers and transaction sizes, higher friction for higher risk) balances compliance and user experience. Turkish KYC obligations under MASAK and BDDK apply to financial services, with specific document and verification requirements that often add Turkish-specific complications for international platforms serving Turkish customers.
