Why are KYB Checks needed in today’s world?

Managers often perform a cursory look-up against common and publicly open data sources such as company registers. In many cases, this type of check may not suffice as businesses face increasingly sophisticated fraud and financial transaction risks, as well regulatory compliance. Therefore, a flexible and more universal Know Your Business tool is required to perform a comprehensive and representative check of a business entity.

How Does Our KYB Process Work?


The Melissa KYB knowledge base is exposed via a single, modern, fast, secure REST API endpoint or as a no code, out of the box service.
The service accepts company data attributes, e.g., names and addresses. The response comes in a JSON format, making it easy to consume by third-party applications such as client or vendor onboarding applications or ERP/CRM products that allow integrations.
Our KYB service provides a structured response and a list of result codes that help the user interpret the result.

Demonstrating Melissa KYB with a Flask-Based Python Web App.


A simple Python web app built with Flask demonstrates the capabilities of the Melissa KYB tool. The app has individual pages for each test company, displaying a business card-like summary of KYB checks with real-time information from the Melissa API.
Input data is stored in a static JSON file, though it could come from other sources in practice. Each company page uses the Melissa API to validate information from the KYB database.
For example, the Austrian company "Test Business AT" is confirmed active with a legal form of GmbH and a high confidence score, indicating it is a legitimate entity.

Frequently Asked Questions

KYB is a process that businesses use to verify and authenticate the identity of their corporate clients or partners. It involves collecting and verifying information to ensure compliance with regulations and to mitigate the risk of fraudulent activities.

KYB is crucial for businesses to establish the legitimacy of their corporate relationships, assess potential risks associated with business partners, comply with regulatory requirements, and maintain a secure and trustworthy business environment.

KYB processes help businesses make informed decisions about their corporate relationships, prevent fraudulent activities, ensure compliance with legal obligations, and safeguard their reputation in the business community.

While there are general principles and guidelines for KYB, specific regulations may vary by country or region. Businesses conducting international transactions may need to adapt their KYB processes to comply with the regulatory frameworks of different jurisdictions.

Challenges in KYB implementation include the need for thorough due diligence, managing the complexity of cross-border transactions, and staying abreast of evolving regulations that impact corporate identity verification.
