What is Unique identification number (UID)?

A Unique Identification Number (UID) in Switzerland is a standardized, 13-digit number assigned to businesses and organizations to identify them across all administrative and commercial systems. Managed by the Swiss Federal Statistical Office (FSO), the UID streamlines interactions with authorities, partners, and customers.

Key Features of the UID in Switzerland

  1. Purpose
    The UID replaces previous identifiers (such as VAT numbers) to provide a unified system for business identification. It is used for tax filings, commercial register entries, and other official purposes.
  2. Assignment and Structure
    • The UID consists of the prefix “CHE” followed by nine digits (e.g., CHE-123.456.789).
    • It is assigned automatically upon a company’s registration in the Swiss Commercial Register or when engaging in economic activities requiring official interaction.
  3. Usage
    Businesses use their UID for invoicing, contracts, VAT filings, and correspondence with Swiss authorities. It ensures consistency and reduces administrative complexity.

Importance of the UID

The UID simplifies processes for businesses by providing a universal identifier, reducing duplication, and improving data accuracy. In Switzerland’s organized and transparent business environment, the UID supports efficient communication between companies and authorities, enhancing operational efficiency and compliance.
