Knowledge base
The code systems behind Hungarian company data, explained. Everything here comes from official sources, and the source is named on every page — we do not guess at the right answer.
The code directories themselves — TEÁOR codes, bank routing codes, postcodes, registry court codes — are Hungarian-language pages; the articles below explain them in English.
How is a Hungarian bank account number structured?
A Hungarian account number is not random: every block has its own job.
TEÁOR'25: what do Hungarian activity codes mean?
All four levels of an activity code live inside the same number — you just need to know where to cut it.
What does a Hungarian company registration number mean?
The first four digits of a registration number tell you where a company was registered and in what form.
How can I verify a Hungarian company's tax number?
Two separate questions: is the number valid, and is there a company behind it? The first can be settled on paper; the second cannot.
What is the KOMA database of debt-free taxpayers?
The most common misunderstanding in Hungarian company data: a place on the KOMA list comes by application, not automatically.
Why are several companies at the same address?
Sharing an address is lawful and common. The question is not how many companies are there, but whether you know what you are looking at.
What does it mean that a company is a VAT-taxable person?
Being a VAT-taxable person is a tax status, not a quality mark. What the registry can tell you is precisely delimited.
How can I check a Hungarian company for free?
A large share of Hungarian company data is public. What matters is which source answers which question — and which question none of them answers.
