Look up a CAEN code
Type the code or the activity. You get the official name, the section and division it belongs to, and — where it applies — what the same code meant in earlier revisions of the nomenclature. No account, no email.
Search by digits or by words, with or without diacritics. The nomenclature is built in, so the answer is instant.
Why the revision matters
CAEN has changed four times: 1998, 2003, 2008 (Rev.2) and 2025 (Rev.3). It is not merely a reordering — the same four-digit code can mean something entirely different. Code 6210 is "custom software development" in the current revision, but was "scheduled air transport" in 2003. Of the codes present in both Rev.2 and Rev.3, 129 carry different names, and 470 Rev.2 codes no longer exist at all in Rev.3.
That is why this tool prints the revision next to every result and warns you when a code means something else elsewhere. A company registered before 2025 still carries an old code in its paperwork, and the balance sheets published by ANAF use the revision of the filing year.
What the levels mean
The section is the capital letter (A, C, K…). The division has two digits, the group three, the class four. The CAEN code in a company's paperwork is the four-digit one — a class.
The main code and the secondary ones
A company declares a single main code — the activity that, in principle, brings in most of the revenue — and may hold any number of authorised secondary codes. The main code is the one that appears first on the company's registration certificate, and the one a partner or a bank usually looks you up by.
Secondary codes are not added “just in case”: each has to be authorised, and some activities need separate approvals before you can invoice under them. If you have started selling something your codes do not cover, the right order is authorisation first, invoice second.
Where you will be asked for it
When opening a bank account and at the periodic reviews banks run, in contracts with larger clients, for insurance, when registering on public procurement platforms, and in almost any financing file. In all of these the declared code is compared against what you actually do — so one that no longer describes your business is a reason for questions, not a formality.
Search by activity, not by code
The nomenclature is written by statisticians, not by entrepreneurs: many classes are called “Other … activities n.e.c.” — not elsewhere classified — and tell you nothing until you have read what the neighbouring classes left out. Searching by the words of the activity almost always works better than guessing a four-digit code.
If what you do seems to fit two classes, that is not a flaw in the nomenclature: one usually describes manufacturing, the other the trade or service attached to it. Pick the one the revenue comes from, not the one that reads better on the certificate.
Where the data comes from
From the nomenclature published by the Romanian Trade Register in the national open data portal. It is built into the app rather than fetched on every search: it changes once in many years, and a tool that depends on someone else for every keystroke is empty exactly on the day that someone else is down.
What we do not do
We do not store what you searched for and we do not ask for your email. Nor do we invent explanations: we print the official name, and that is it. Which permits a given activity requires depends on the law and on the authority that issues them.
