What Is the Enterprise Identification Number (UID)? All About the UID in Switzerland

The Enterprise Identification Number (UID) is a vital tool for identifying businesses in Switzerland. Introduced to simplify administrative processes, the UID system enables businesses to be easily recognized by public and private authorities. In this article, we explore what the UID represents, how it works, and why it is essential for companies operating in Switzerland.

What Is the UID?

The UID is a unique nine-digit code officially introduced in Switzerland in 2011. Its format follows an international standard: CHE-123.456.789. The UID was designed to replace various identification numbers previously used by different authorities, such as VAT numbers and commercial register codes, with a centralized and more efficient system.

What Is the Purpose of the UID?

The UID was introduced to enhance administrative efficiency and reduce bureaucracy for businesses. With the UID, a company can:

• Identify itself with public authorities: Such as the Commercial Register, the Federal Tax Administration (FTA), or the Swiss Federal Statistical Office (SFSO).
• Facilitate transactions with private parties: By using the UID on invoices, contracts, or other official documents.
• Manage digital correspondence: Many online platforms require the UID to verify a company’s identity.

Who Receives a UID?

The UID is automatically assigned to:

• Businesses registered in the Commercial Register.
• Economic entities not registered (e.g., associations or foundations) but with tax or statistical obligations.
• Sole proprietors, if registered as such.

A key feature of the UID is that it remains unchanged even in the case of corporate changes, such as name or address modifications. This ensures administrative continuity.

How Can You Find a Company’s UID?

A company’s UID can be easily retrieved using the UID Register (UID Register). By entering the company’s name or other details, you can access up-to-date information, including:

• The UID.
• The company’s official name.
• The registered address.

Why Is the UID Important for Businesses?

Using the UID is mandatory in many areas, such as:

• Issuing invoices: For businesses subject to VAT, the UID replaces the old VAT number.
• Official communications: Including tax declarations, statistical documents, or authorization requests.
• Interactions with business partners: Suppliers and clients can use the UID to verify a company’s identity.

The UID also simplifies corporate change processes, as all updates (e.g., address changes or board member modifications) are linked to the same identification number.
