Overview

Know Your Business (KYB) is the process of verifying a business entity's legal existence, structure, ownership, and authorization to conduct payment processing activities. While KYC (Know Your Customer) focuses on individual identity verification, KYB validates the business itself.

Why KYB Matters

For Payment Facilitators:

  • Regulatory Compliance: FinCEN Customer Due Diligence (CDD) Rule requires identifying and verifying beneficial owners
  • Risk Management: Prevents shell companies, fraud schemes, and money laundering operations
  • Sponsor Bank Requirements: Banks mandate comprehensive business verification before enabling payment processing
  • Network Rules: Visa and Mastercard require proper merchant identification and monitoring

For Merchants:

  • Establishes trust and credibility
  • Enables payment processing capabilities
  • Provides access to financial services
  • Protects against identity theft and fraud

Key Difference

KYB verifies the business exists legally and identifies who controls it. KYC verifies individual identities. Both are required for complete merchant onboarding.

Key Terms

Articles of Incorporation/Organization: Legal documents filed with the state to create a corporation or LLC, containing business name, purpose, registered agent, and initial directors/members.

Certificate of Good Standing: Official state document confirming a business is properly registered, current on filings and fees, and authorized to conduct business.

DBA (Doing Business As): Fictitious business name registration allowing a business to operate under a name different from its legal name.

EIN (Employer Identification Number): Federal tax ID issued by the IRS for business entities, similar to an SSN for individuals.

Operating Agreement: Internal LLC document outlining ownership percentages, management structure, and operating procedures (not filed with the state).

Corporate Bylaws: Internal rules governing corporation management and operations (not filed with the state).

Registered Agent: Person or entity designated to receive legal documents and official correspondence on behalf of a business.

Business License: Permit issued by local, state, or federal government authorizing specific business activities (industry-dependent).
