Checking a Slovenian company's VAT registration
A Slovenian company becomes liable for VAT by registering with the Slovenian Financial Administration. On registration it is assigned a VAT identification number, made up of the prefix SI and eight digits. That number is the only reliable way to confirm a partner really accounts for VAT.
The check runs against VIES (the VAT Information Exchange System) operated by the European Commission. It returns the current registration status across the whole EU, so a foreign supplier is verified exactly the same way.
What you can enter
- Company ID — ten characters. We find the entity in the register and check its VAT number.
- VAT number (ID za DDV) — for example SI12345678. Checked directly in VIES.
- Company name — we return the matches and you pick the right company.
Frequently asked questions
- How do I check whether a company is registered for VAT?
- Enter the company's company ID, VAT number or name in the search above. If the company has a VAT number, we verify it directly against the European Commission's VIES system and show the current result.
- Is there a public list of VAT payers in Slovenia?
- The Slovenian Financial Administration maintains the register of VAT-liable persons and publishes a lookup in its e-services. To check one specific company it is faster to enter its company ID or VAT number — you get an answer immediately, without searching a whole list.
- What is the difference between a company ID and a VAT number?
- The matična številka is the ten-character number the business register assigns to every entity on registration. A VAT number is issued only to a business identified for VAT purposes and takes the form SI plus eight digits. Every registered entity therefore has a matična številka; not every one has a VAT number.
- Why does a partner's VAT number matter?
- If a supplier puts an invalid VAT number on an invoice, it can cause problems when deducting input VAT. Checking it in VIES is a routine part of vetting a new business partner.
