Disclosure Of Registration Numbers.
Disclosure of Registration Numbers
Disclosure of registration numbers refers to the legal obligation of companies, partnerships, and other corporate entities to display, disclose, and use their official identification numbers (company registration number, tax ID, or equivalent) in documents, communications, and regulatory filings. These obligations ensure transparency, legal accountability, and traceability.
This requirement is particularly relevant in company documentation, contracts, websites, invoices, and statutory filings.
1. Legal Framework
(a) Companies Act / Corporate Law Requirements
UK:
Companies Act 2006, Sections 82–85
Every company must display its registered company number (RCN) on all business correspondence, invoices, websites, and official communications.
Failure may lead to fines or invalidity of legal documents.
India:
Companies Act 2013, Section 12 & 129
Companies must display their Corporate Identification Number (CIN) on official documents and invoices.
Required in statutory filings, tax communications, and annual reports.
U.S. (Delaware / Federal)
Corporations are issued File Numbers or Entity IDs for incorporation; disclosure is often required in SEC filings or corporate registrations but less frequently on commercial correspondence.
International Stock Exchanges:
Registration numbers are typically required in prospectuses, annual reports, and regulatory filings for traceability.
(b) Purpose of Disclosure
Transparency – Allows stakeholders to verify the legal existence of the entity.
Accountability – Identifies the entity responsible for contracts and statutory obligations.
Regulatory Compliance – Ensures filings, taxation, and reporting are traceable to a unique entity.
Contractual Clarity – Reduces disputes by clearly identifying the contracting party.
