Check Hungary VAT numbers
Validate Hungarian VAT numbers (ANUM) against the EU VIES registry. Hungarian numbers are HU followed by 8 digits. The domestic Adószám is 11 digits (with group code and county code appended); the EU-format ANUM strips those suffixes to 8 digits. Every response includes the company name, registered address, and validity at query time.

Watch out for
- Hungarian ANUM is 8 digits; do not send the full 11-digit domestic Adószám (which adds group code + county code). VIES rejects 11-digit HU numbers.
- Hungary's 27% standard VAT rate is the highest in the EU; double-check invoices from HU suppliers if the rate looks unexpectedly high.
- VAT grouping is permitted in Hungary; individual group members may not appear in VIES under their own ANUM.
Hungarian VAT identifiers
Hungarian VAT numbers are 8 digits prefixed with HU. The full
structure is HU followed by 8 digits where:
- The first 8 digits are the adószám (tax number).
- A domestic-form Hungarian adószám is actually 11 digits in total (8 + 1 VAT-status digit + 2 county code), but only the first 8 are used for the EU-facing form that flows through VIES.
vatverify accepts the EU-form HU\d{8} and routes it through VIES.
The 11-digit domestic form is recognized as input, with the trailing
3 digits stripped before the registry call.
NAV is the tax authority
The Hungarian tax administration is NAV (Nemzeti Adó- és Vámhivatal, National Tax and Customs Administration). NAV maintains the VAT register and pushes updates to VIES on a regular batch cadence.
The 9th digit of the full domestic adószám encodes the entity's VAT status (regular taxpayer, VAT-exempt below threshold, group-member, and a handful of special-status categories). The exact mapping is maintained by NAV; for reconciling Hungarian invoices it is useful to recognize the position rather than to hardcode the codes, since specific category values have been adjusted as Hungarian VAT regimes have changed.
For VIES purposes only the first 8 digits matter.
ÁFA rates: 27%, 18%, 5%, 0%
Hungary runs the highest standard VAT rate in the EU at 27%, with two reduced rates at 18% and 5%, and a 0% rate for a defined set of supplies including newspapers and several specific medical and educational services.
The 18% bracket covers dairy, certain bakery products, and accommodation. The 5% bracket covers basic foodstuffs (some types of meat, milk, eggs), books, newspapers, pharmaceuticals, and new residential properties under defined conditions.
Hungarian rate composition has been adjusted multiple times in recent budget cycles. Hardcoded rate constants will go stale; date-aware lookups against current NAV publications are the safer default.
NAV Online Invoice: mandatory e-invoicing
Hungary operates one of the EU's earliest mandatory e-invoicing regimes, the Online Számla (Online Invoice) platform. Hungarian VAT-registered businesses are required to transmit invoice data to NAV in real time.
The mandate has expanded across thresholds and counterparty types since 2018. For non-Hungarian sellers invoicing Hungarian buyers, the Online Számla obligation typically falls on the Hungarian buyer under self-billed reverse-charge. The seller still needs to validate the buyer's adószám through VIES before zero-rating.
Reverse-charge for several sectors
Hungary applies domestic reverse-charge to scrap metal, mobile phones, integrated circuits, gas, electricity, cereals, oilseeds, and several other categories historically associated with carousel fraud. These rules apply between two Hungarian VAT-registered businesses and are independent of EU intra-Community reverse-charge.
Cross-border with neighbours
Hungary borders Austria, Slovakia, Slovenia, Croatia, Romania (all EU), Ukraine, and Serbia (third countries). Standard EU intra-Community reverse-charge applies to B2B supplies between Hungary and other-EU VAT-registered businesses.
For Ukrainian and Serbian counterparties, third-country export rules apply. Sanctions and trade-agreement rules also affect what is permitted in specific sectors.
Caching against the NAV cycle
NAV pushes registration changes to VIES on a regular batch. Newly-registered Hungarian adószámok are generally visible in VIES within 24 to 48 hours. vatverify's default TTLs (30 days for valid, 24 hours for invalid) line up with this cadence.
