Frequently Asked Questions
Answers to the most important questions about the Slovak VAT ID.
What terms are used for the Slovak VAT ID?
The Slovak VAT identification number is known by several names: VAT ID, IČ DPH, Slovak VAT. Also referred to as VAT number SK or Slovakia VAT ID. All terms refer to the same number registered in the EU VIES system.
What is the difference between VAT ID, tax number (Steuernummer) and MwSt number?
The VAT ID (also known as USt-IdNr., UID, UStID, MwSt-Nummer, VAT Number) is the VAT identification number for the EU single market — with country code (SK) and verifiable via the VIES system. The tax number (Steuernummer) is a purely national identifier issued by the local tax office and has no relevance for cross-border trade. "Umsatzsteuer-Nummer" is often used synonymously but technically means the VAT ID. The terms "MwSt-Nummer" and "Mehrwertsteuer-Nummer" refer to the same number — only the label differs.
What is the format of an Slovak VAT ID?
The Slovak VAT ID consists of the country code SK followed by the national number structure, e.g. SK1234567890. It is issued by the national tax authority (Financial Administration of the Slovak Republic) and registered in the EU VIES system.
When do I need to verify an Slovak VAT ID?
VAT ID verification is required for: intra-community supplies to or from Slovakia, cross-border B2B services, tax-exempt invoicing to Slovak business partners, and as good-faith proof during tax audits. The consultation number from a qualified check is a legally binding record.
