Mandatory ID Verification for Company Directors: Technical Breakdown and Developer Insights

Mandatory ID Verification for Company Directors: Technical Breakdown and Developer Insights

Introduction

Starting on November 18, 2025, company directors, trustees, and persons with significant control (PSCs) will be required to provide a 'personal code' when submitting confirmation statements to Companies House. This new regulation aims to enhance transparency and security in corporate governance. For developers, this means integrating with the new identity verification systems and ensuring smooth compliance.

Technical Requirements for Identity Verification

The identity verification process involves two primary routes: the government's free online service and authorized corporate service providers (ACSPs). Both methods require developers to understand the technical specifications and API endpoints to facilitate seamless integration.

Government's Online Identity Verification Service

1. API Integration: Developers must integrate with the Gov.UK One Login service API. This involves setting up OAuth 2.0 authentication to allow users to link their Companies House accounts with their One Login accounts.

1. Document Scanning: The verification process requires scanning documents such as biometric passports, driving licenses, and residence permits. Developers should implement robust document scanning and validation features, ensuring high accuracy and security.

1. Biometric Data Handling: For biometric passports, developers need to handle the scanning of the chip on the passport. This involves using NFC (Near Field Communication) technology to read the data and verify its authenticity.

Authorised Corporate Service Providers (ACSPs)

1. Third-Party API Integration: If a company opts for an ACSP, developers must integrate with the ACSP's API. This often involves handling additional fees and ensuring data security and compliance with data protection laws.

1. User Experience: ACSPs may offer a more user-friendly experience, but developers should still focus on creating a seamless and intuitive process for users.

Practical Tips for Developers

1. API Testing: Thoroughly test the API integration to ensure that all endpoints are functioning correctly. Use mock data and real-world scenarios to identify and fix any issues.

1. Security Measures: Implement strong security measures to protect sensitive user data. This includes using HTTPS, encrypting data at rest, and following best practices for handling biometric data.

1. User Support: Provide clear instructions and support for users. This may include step-by-step guides, FAQs, and a dedicated support line to help users navigate the verification process.

1. Compliance Monitoring: Stay updated with the latest regulations and guidelines from Companies House. Regularly review and update your systems to ensure ongoing compliance.

Hypothetical Impact on Developer Workload

Projections suggest that the new identity verification requirements could increase the developer workload by 15-20% in the initial implementation phase. However, the long-term benefits of enhanced security and compliance are expected to outweigh the short-term challenges.

The Bottom Line

The mandatory ID verification for company directors presents a unique opportunity for developers to enhance their systems and ensure compliance with new regulations. By understanding the technical requirements and implementing robust solutions, developers can help their organizations navigate the transition smoothly and securely.
