Vacation Rental Registration Number: What Really Takes Effect in 2026

A significant amount of misinformation has appeared in Croatia's short-term rental sector regarding the introduction of a mandatory registration number for accommodation units. Many hosts are concerned about incorrect deadlines and unclear instructions.

This guide provides only verified information based on official sources. We will explain exactly what EU Regulation 2024/1028 entails, what the actual deadline for its implementation is, and what hosts in cities like Split, Dubrovnik, and Rovinj can do today to be prepared.

— 01What Is EU Regulation 2024/1028 and Why Is It Important for Croatia?

EU Regulation 2024/1028 is a new legislative framework from the European Union that introduces a unified registration system for short-term accommodation rentals. The goal is to increase transparency, facilitate data and tax collection, and ensure all hosts operate under the same conditions, thereby combating the significant grey market economy.

For Croatia, a country where tourism generates over 20% of the GDP, this regulation is extremely important. By introducing a single register, the state gains precise insight into the number and location of active accommodation units, enabling better spatial planning and more efficient tax collection. Platforms like Booking.com, Airbnb, and VRBO will be legally obligated to verify and display this number on every listing.

The regulation does not introduce new taxes but ensures that existing ones, such as the paušalni porez (flat-rate tax per bed), are collected more effectively. This protects hosts who operate legally and creates a more level playing field in the market.

— 02When Does the Registration Number Actually Take Effect?

The key date for the full implementation of the requirement to have and display a registration number is May 21, 2026. Information about earlier deadlines, such as May 20 of this year, is misinformation. The Ministry of Tourism and Sport (MINT) and expert portals like Cimerfraj have confirmed that hosts have sufficient time to adapt ^[1].

Although the Regulation formally entered into force in May 2024, it gives member states a 24-month period to establish a national digital registration system. Therefore, Croatia must have a functional system by May 21, 2026, through which hosts can request and receive their number.

Once the system is operational, platforms will have an additional, shorter period to adapt their systems to technically verify the validity of the entered numbers. This means the entire ecosystem—from hosts to platforms—will be fully compliant during 2026.

— 03Registration Number, eVisitor ID, and Categorization Decision: What's the Difference?

The registration number is a completely new, unique identifier that each accommodation unit will receive under the EU Regulation. It should not be confused with the rješenje o kategorizaciji (categorization decision), which is an administrative act confirming compliance with requirements, nor with the eVisitor ID, which is used exclusively for registering guests in the national tourist system.

To avoid confusion, it is crucial to understand the purpose of each of these identifiers. The categorization decision proves that your apartment in Trogir or holiday home on Hvar meets the minimum technical conditions and standards prescribed by the Hospitality and Catering Industry Act ^[2]. On the other hand, your eVisitor ID is your user access credential for the guest registration system.

This table clearly shows the key differences:

The new registration number will be publicly visible and will serve as a quick legality check for guests and competent authorities.

— 04Who Issues the Number, How Do You Apply, and What Does It Cost?

The registration number will be issued by a competent national authority, which in Croatia will most likely be integrated into the existing eVisitor system managed by the Ministry of Tourism and Sport. The registration process will be entirely digital and, according to the Regulation, free of charge or subject to a minimal, proportionate fee that covers only administrative costs.

The application process will require entering data that hosts are already familiar with:

• Host Information: Name and surname or company name, OIB (Personal Identification Number).
• Property Information: Exact address, type of accommodation unit (apartment, room, holiday home).
• Capacity: Maximum number of guests the unit can accommodate, in accordance with the categorization decision.
• Categorization Decision Number: As proof that the unit operates legally.

After data entry and verification, the system will automatically generate a unique registration number for each individual accommodation unit. If you own three apartments in the same building in Pula, you will receive three different registration numbers.

— 05Penalties for Non-Compliance and Enforcement: What Awaits Hosts Without a Number?

Hosts who do not display a valid registration number on their listings after May 21, 2026, will face serious consequences. Platforms like Booking.com and Airbnb will be required to remove such listings, and competent authorities (State Inspectorate, Customs Administration) will be able to impose fines.

The Regulation introduces a dual control mechanism:

1. 1 Online Platforms: They will have to establish processes to verify the validity of registration numbers. If a number is incorrect or missing, the platform is obligated to temporarily deactivate or permanently remove the listing.
2. 2 National Authorities: The State Inspectorate (Državni inspektorat) and other competent bodies will conduct random checks and act on reports. Hosts found in violation will be sanctioned.

Although the exact fine amounts for Croatia have not yet been defined and will be prescribed by amendments to domestic laws, they are expected to be in line with the practices of other EU countries, where they range from several hundred to several thousand euros per violation.

— 06What Can You Do NOW to Be Prepared?

Although the deadline for adaptation is May 2026, hosts can already take key steps. The most important thing is to ensure that all existing documentation, such as the rješenje o kategorizaciji and data in eVisitor, is up-to-date and accurate, as this information will be the basis for issuing the new registration number.

Prepare in time with this simple checklist:

• Check Your Documentation: Make sure your categorization decision is valid and that the data on it (e.g., number of beds) matches the actual situation.
• Update eVisitor: Log in to the eVisitor system and verify that all information about your accommodation units is correct—address, capacity, contact details.
• Follow Official Sources: Regularly check the website of the Ministry of Tourism and Sport for official announcements about the establishment of the register.
• Avoid Misinformation: Do not fall for unverified information from forums or offers for "quick registration" services. The entire process will be official and digital.

By organizing your administrative data now, you ensure that the transition to the new system in 2026 will be quick and painless. The introduction of the registration number is a step towards professionalization and market transparency, which ultimately benefits all legal hosts.
