What is a UID?
The UID (Unique Identification Number) is the Swiss business identifier, typically formatted as CHE-XXX.XXX.XXX. It is used to identify legal entities in administrative and commercial contexts.
Key Features
- Standard business identifier across authorities
- Used in official documents and business correspondence
- Helps align records across providers and counterparties
- Distinct from VAT registration status itself
Practical Usage
- Include UID consistently on formal business documents
- Use exact formatting across contracts and invoicing systems
- Keep registry data aligned with UID references
- Confirm VAT status separately where required
Tax and Compliance Implications
Inconsistent UID usage can trigger administrative mismatches and onboarding delays. Accurate company master data supports smoother tax, accounting, and compliance workflows.
