Swiss UID & VAT Number Validator

Check Swiss UID and VAT numbers in bulk against the official UID register of the Swiss Federal Statistical Office (BFS). You get the register status, the VAT status, the legal form and, for companies, the registered name and address. USD 0.004 per number checked (USD 4 per 1,000). EU VIES does not cover Switzerland. This actor does.

Input	Found	Status	VAT status	Name

CHE-123.456.789	no	-	-	- (wrong check digit: free, no register call)

The rows come from a real cloud run of 04.11.2026. The full item is under Output.

Who uses it

• Invoicing and accounting tools: check that a Swiss customer's VAT number is active before you invoice.
• KYB and supplier onboarding: confirm that a Swiss company exists, is active and has the stated legal form.
• CRM clean-up: check your Swiss UIDs once a month and flag deleted entries and ended VAT registrations.

What it does not do

• It does not search by name. You need the number.
• Sole traders and partnerships come back without name and address (personal data, see below).
• The register allows 20 lookups a minute. 1,000 numbers take about an hour.
• Only the commercial register's publications are legally binding.

Input

{ "uids": ["CHE-102.753.938", "CHE-101.654.423 MWST", "102753938"] }

Any common spelling is accepted. Up to 5,000 numbers per run. The register allows 20 lookups a minute. A long list takes longer.

Pricing (pay per event)

Event	Price	When
uid-checked	USD 0.004	one number looked up in the register - found or not found

Free: numbers that fail the check-digit test (no register call), and numbers the register could not be reached for. 1,000 checks cost USD 4.

Personal data

Entries of natural persons - sole proprietorships, general and limited partnerships, simple partnerships, and entries without a legal form - come back with personalDataWithheld: true: existence, status and VAT status only, no name, no address, no IDs. Address lines that may name a person (c/o ...) are not returned for anyone. There is no search by name.

A company named after a person keeps its name, because it is a legal person.
