The United Kingdom is one of the world's most important financial centers and home to over 5 million registered companies.

Key Identifiers of a UK Company
The Company Number is the unique identifier assigned to each company by Companies House upon registration. It consists of 8 characters and never changes. It is the primary reference and must appear on all official company documents.
The UTR (Unique Taxpayer Reference) is the company's tax identifier with HMRC. It is not public but can be requested in a commercial relationship.
The VAT number begins with "GB" followed by 9 digits. Verifiable through HMRC's portal or the European VIES system.
