CUI is one of the most important identification elements of a company in Romania. Whether we are talking about commercial companies, sole traders (PFA), or NGOs, this code is essential for the legal and fiscal operation of an entity. The CUI appears on invoices, contracts, official documents, and in direct relations with state institutions, especially the National Agency for Fiscal Administration (ANAF).
Its importance is major because it allows the quick and unique identification of an economic entity in fiscal and administrative systems. Without this code, a company cannot issue legal documents, cannot be registered for tax purposes, and cannot carry out economic activities legally.
In relation to ANAF, the CUI becomes the key through which a company’s tax obligations, declarations, and financial history are monitored. In practice, it is the “fiscal ID card” of any economic entity in Romania.

What does CUI mean?
CUI is the acronym for “Unique Identification Code” and represents a unique number assigned to each legal entity in Romania. This code is used to identify the company in relation to the state, business partners, and in all fiscal documents.
In concrete terms, the CUI is used for the fiscal records of a company and is managed by state institutions, especially the Ministry of Finance and ANAF. Each company has a single CUI, which remains unchanged throughout its existence, regardless of internal changes (such as changing the administrator or registered office).
The CUI appears on all official company documents: invoices, receipts, contracts, tax declarations, and any other document involving economic activity. It is also used for tax reporting and identifying obligations to the state.
It is important to note that this is not just an administrative number, but an essential element in the legal functioning of any business in Romania.
Who receives a CUI and when is it assigned?
The Unique Identification Code is assigned to all legal entities that carry out economic activities or are officially registered in Romania. These include:
- Commercial companies (SRL, SA, etc.)
- Authorised Natural Persons (PFA)
- Individual and Family Enterprises
- Non-Governmental Organisations (NGOs)
- Cooperatives and other legal forms recognised by law
The CUI is assigned at the moment of company registration with the Trade Register or the competent institution, depending on the legal form. For example, for limited liability companies (SRL), the process takes place at the National Trade Register Office, and the data is subsequently transmitted to the Ministry of Finance and ANAF for tax registration.
In the case of sole traders (PFA), the CUI is issued at the moment of business authorisation and tax registration. NGOs receive a CUI upon registration in the register of non-governmental organisations.
The link with the Ministry of Finance is essential, as it manages the national tax database. ANAF uses the CUI to monitor taxes, duties, and reporting obligations of each entity.
In practice, the CUI is issued only once and remains unchanged throughout the entity’s existence, being used as the main identifier in all interactions with the state.
How do you check your CUI in ANAF and the Ministry of Finance?
Checking a CUI is a simple and free process, but extremely important for anyone who wants to collaborate with a company or verify its legality. There are two main official sources: the ANAF website and the Ministry of Finance platform.
The first step is accessing the official portal of the Ministry of Finance, where there is a section dedicated to taxpayer information. There, you can enter the company’s CUI and obtain data such as the company name, tax status, and sometimes even activity history.
On the ANAF website, the verification is mainly focused on the company’s tax status. Here you can find out whether the company is active, fiscally inactive, or has certain restrictions. ANAF does not always provide detailed commercial information, focusing instead on the fiscal side.
The main difference between ANAF and the Ministry of Finance is the level of detail and the purpose of the information. The Ministry of Finance provides a more general overview of the company, while ANAF focuses strictly on tax compliance.
By checking the CUI, you can obtain essential information before signing a contract or starting a collaboration, reducing the risk of fraud or non-payment.
How do you search for a company by CUI?
Searching for a company by CUI is one of the safest methods of verifying the identity of an economic entity in Romania. In practice, the CUI acts as a unique “tax ID”, and entering it into official platforms allows you to quickly identify the correct company, without the risk of confusion.
To search for a company, you can use the official websites of the Ministry of Finance or ANAF, where there are dedicated sections for taxpayer verification. By entering the CUI, you will obtain the company name, its tax status, and other relevant basic data.
It is important to remember that public data includes information such as the name, registered office address, tax status, and sometimes details about VAT registration.
This method is extremely useful for checking business partners. Before signing a contract, many companies check the CUI to ensure the company is active and legally registered.
There is also a direct link with the Trade Register, as the company’s initial data is recorded there and later transmitted to ANAF and the Ministry of Finance for tax records.
What information can you find about companies and taxpayers by CUI?
The CUI gives you access to a range of public information about a company or taxpayer. This data is essential for business transparency and for preventing commercial risks.
The most important information includes:
- Full company name
- Registered office address
- Tax status (active, inactive, suspended)
- CAEN code (main activity domain)Date of incorporation
The CAEN code is particularly important because it shows exactly the field in which the company operates, whether it is trade, services, construction, or IT.
You can also check whether the company is fiscally active or inactive, which is essential before entering into a collaboration. A fiscally inactive company does not have the right to carry out legal economic activities.
The year of incorporation gives you insight into the company’s market experience, which can influence business decisions.
What is the difference between CUI, CIF and VAT code?
Although they are often confused, CUI, CIF, and VAT code have different roles in the Romanian tax system.
CUI (Unique Identification Code) is the main identification number of a company and is assigned at its registration. It is used for all official interactions with the state.
CIF (Fiscal Identification Code) is, in many cases, the same as CUI, but the term is mainly used in tax contexts. In practice, for most companies in Romania, CUI and CIF are identical.
The VAT code is different. It is assigned to companies registered for VAT purposes. A company may have a CUI but not be VAT registered. In this case, it will not have a VAT code.
For example, on an invoice you may see:
- CUI: 12345678
- RO12345678 (VAT code)
The difference is important for accounting and for determining the tax regime of transactions.
Can you check ANAF debts by CUI?
Yes, but only partially and under certain conditions. Checking a company’s debts via CUI is possible only for public and aggregated information.
ANAF publishes lists of taxpayers who have outstanding obligations or who are declared fiscally inactive. This information can be consulted using the CUI, but you will not have access to full details about the exact amounts owed.
It is important to understand that certain tax data is protected by fiscal confidentiality legislation. Therefore, not all debt information is public.
Correct interpretation of this data is essential. A company with debts is not necessarily unreliable, but it may represent a risk in commercial collaborations.
For this reason, checking the CUI should be combined with other analyses before making a business decision.
Common mistakes when checking a company’s CUI
One of the most common mistakes is confusing CUI with a personal identification number (CNP). The CUI belongs to a company, while the CNP belongs to a natural person. The two are not directly related.
Another frequent mistake is using unofficial websites for company verification. These may display incomplete or outdated information, which can lead to wrong decisions.
Many users also misinterpret a company’s tax status. For example, a “fiscally inactive” company is not necessarily dissolved, but simply suspended from a tax perspective.
Another error is incomplete data checking. Many people only look at the name, without verifying the CAEN code, VAT status, or fiscal history.
Conclusion: Why it is important to know what CUI means and how to check it
The CUI is an essential element in the identification and functioning of any company in Romania. It allows access to important fiscal and legal information and is used in all official interactions with the state.
For entrepreneurs and companies, checking the CUI before signing a contract is an essential safety step. It reduces commercial risks and helps avoid collaborations with inactive or unreliable companies.
It is important to always use official sources such as ANAF or the Ministry of Finance for verification, avoiding unauthorised platforms.
Remember: checking the CUI is a simple but extremely important step in any business relationship.
Always check a company by its CUI before signing a contract and save this guide for quick reference.
