In this article, you will find specific answers to questions about the risks arising from insufficient geo-blocking of gambling services and how to properly restrict access from prohibited jurisdictions. We explain why geographic restrictions alone are not enough and which legal and technical tools you must combine, in line with legislation applicable in 2026, to avoid significant fines.

Quick summary

  • Geo-blocking in gambling is an essential tool for complying with licensing conditions under Czech legislation and national regulations across the EU.
  • Czech operators must prevent access by persons from jurisdictions where they are not authorised to operate.
  • Although geo-blocking may sound like a simple technical matter, in practice it involves complex compliance with AML rules, identity verification, payment methods, and contractual allocation of liability.

What is geo-blocking in the context of gambling?

Geo-blocking is a technical and legal measure that restricts access to gambling services based on the user’s geographic location. In practice, it is a system that uses an IP address, GPS location, or other identifiers to decide whether to allow a user to register or participate in a game. In the gambling industry, this measure is crucial because gambling is not harmonised at EU level and there is no “single European licence”.

If you operate an online casino, sportsbook, or other gambling services, you must respect the principle of territoriality. A licence granted by the Ministry of Finance of the Czech Republic authorises you to operate primarily for players located in the Czech Republic. Without proper geo-blocking, you risk allowing play by persons from a jurisdiction where you do not have permission, which may be classified as illegal operation of gambling services.

Related questions on geo-blocking

1. What happens if geo-blocking does not work properly?
If you allow participation by persons from a jurisdiction where you do not hold a licence, you commit an administrative offence under Czech law. The local regulator may initiate proceedings, impose a fine, and in extreme cases initiate blocking of your website and payments in that territory.

2. Does geo-blocking differ depending on the type of gambling?
In principle, no, but legislative requirements for player registration and verification may differ. While identity verification is very strict for fixed-odds betting, requirements for certain types of lotteries may differ abroad. In the Czech Republic, however, the law requires thorough registration and verification for most online games.

3. Is geo-blocking explicitly stated in the law?
The Czech Gambling Act imposes an obligation on the operator to ensure that persons prohibited by law do not participate in games. Although the term “geo-blocking” is not defined directly in the legislation, it is in practice the only way to meet the requirement not to provide services where the law prohibits it.

EU and Czech Republic legal framework

It is necessary to distinguish between the general EU Geo-blocking Regulation, which prohibits unjustified blocking of customers in the internal market, and gambling regulation. Gambling services are expressly excluded from this regulation, which means an operator may differentiate based on location in order to comply with national laws.

In the Czech Republic, the key legislation is the Czech Gambling Act, with online gambling subject to strict licensing control by the Ministry of Finance of the Czech Republic and supervision by the Czech Customs Administration. All legal gambling services must be connected to the Gambling Information System (AISG), which is used for reporting data to the supervisory authorities.

An operator holding a Czech licence must ensure compliance with Czech law, and if it targets foreign markets, it must obtain a licence in each individual country. If it does not hold a licence in a given country, it must technically prevent access by players from that country, as also confirmed by the Court of Justice of the European Union.

ARROWS advokátní kancelář’s Czech legal team routinely sets operating terms to ensure compliance both with Czech law and with requirements to avoid cross-border interference with other jurisdictions. Effective geo-blocking is the only defence against allegations of illegal operation of gambling services abroad.

Related questions on the legal framework

1. Do I have to follow the rules of every country where my website can be accessed?
Technical accessibility of a website does not automatically mean “operating” in that country, but if you localise the website for a specific country without a licence, you are breaching the law. Geo-blocking is an effective defence to demonstrate that you are not targeting that market.

2. Is GDPR in conflict with geo-blocking?
No, provided that processing location data is necessary to comply with a legal obligation. Under Czech legislation, the operator has a legal duty to verify whether the player meets the conditions to participate, but must comply with the data minimisation principle.

3. What risks does ARROWS advokátní kancelář address?
We represent clients in administrative proceedings before the Ministry of Finance and the Czech Customs Administration, prepare Terms & Conditions, and ensure compliance with Czech AML legislation, which is closely linked to client identification.

Practical challenges of implementing geo-blocking

Operators often face a conflict between technical capabilities and legal requirements, because the law requires certainty while technology offers probability. The first issue is identifying the end user, as an IP address is not a perfect indicator due to VPNs and proxy servers. The Czech Gambling Act therefore requires so-called strong identity verification at registration, for example in-person identification or via BankID.

The second issue is system complexity, because gambling platforms today include mobile applications as well as APIs for third parties. If you block the website but leave the API open for a mobile app, the system has gaps and supervisory authorities will detect these failures.

The third aspect is contractual liability, because many operators use games from external suppliers. It is necessary to ensure contractually that the game supplier will respect your geo-blocking settings and will not offer the game in jurisdictions that you, as the operator, have excluded.

Related questions on implementing geo-blocking  

1. Is it enough to outsource geo-blocking to a third-party provider?
From the regulator’s perspective, the licence holder is always responsible, so if the supplier fails, you pay the fine. That is why it is crucial to have a robust SLA and legal recourse in case of failure.

2. Am I required to inform players that they are being geo-blocked?
From a user experience and transparency perspective, yes, but legally the key point is that you must not allow play. A message such as “The service is not available in your country” is standard.

3. How should the technical solution be structured from a legal perspective?
ARROWS advokátní kancelář works with IT specialists on compliance audits where we define “red lines”. These are jurisdictions and scenarios that the system must block unconditionally.

Risks and penalties for non-compliance with geo-blocking

Breaches of rules on territorial scope and the illegal operation of gambling are sanctioned very harshly, both by Czech authorities and by foreign regulators. For operating a gambling game in breach of a licence or the law, a legal entity may face a fine of up to CZK 50,000,000 under Czech legislation. Although fines in practice tend to be lower, serious and systemic failures can reach millions of Czech crowns.

There is also a risk of being entered on the List of Unauthorised Internet Games if an entity targets players without a licence. This results in mandatory website blocking by internet service providers and payment blocking by banks, based on the List of Unauthorised Internet Games.

Repeated breaches of the rules may lead to proceedings to revoke the basic authorisation, because to obtain and maintain a licence the operator must be of good repute under Czech law. In extreme cases, illegal gambling operations may also be classified as a criminal offence in the Czech Republic.

Player protection and prevention of unauthorised access

Geo-blocking is closely linked to player protection, as Czech legislation places emphasis on protecting vulnerable persons. This includes the obligation to verify whether a player is recorded in the Register of Excluded Persons (RVO). Modern compliance systems must integrate geolocation at login, identity verification, and automated checks against the Register of Excluded Persons. 

It is also essential to detect anomalies, where the system must respond to suspicious location changes—such as a rapid login from another country—by blocking the account. Without these layers, it is not possible to legally operate online gambling in the Czech Republic in 2026, because IP address checks alone are no longer considered sufficient.

Related prevention questions

1. Can I rely only on the player’s declaration of residence?
Definitely not—Czech law requires verification of data from reliable sources such as an identity document, a bank statement, or state registers.

2. What if a Czech player connects while on holiday abroad?
That depends on the legislation of the country where they are located and on your terms and conditions. However, as a precaution, many operators proactively block access from foreign IP addresses.

3. How long should data be retained?
Under the Czech AML Act, 10 years from the end of the business relationship; under the Gambling Act (ZHH), there are specific retention periods for gaming data. 

Technical solution vs. legal obligations

Separating IT development from the legal department is a critical mistake, because a developer typically does not know the detailed nuances of the Czech Gambling Act.

The first step is a legal analysis of the markets, which determines where you want to expand and where you hold a licence. A lawyer defines the technical requirements—for example, prohibiting access for players from Germany—and the IT department then determines the method of blocking.

This is followed by implementation and testing, including penetration tests focused on bypassing geo-blocking using VPNs. The system must also be able to demonstrate its functionality to the regulator in the form of a detailed game plan. ARROWS attorneys in Prague provide the essential link between the world of legal provisions and the world of IT code. We ensure that the technical solution meets regulatory requirements under Czech law and withstands inspections by supervisory authorities.

Cooperation with regulators and licensing authorities

Communication with the Ministry of Finance and the Czech Customs Administration requires expertise. In 2026, most reporting is automated via AISG, but administrative proceedings still take place through oral hearings and written submissions. If you discover a technical error in geo-blocking, it is better—after consulting a lawyer—to report and fix it than to wait for an inspection. Good practice also includes auditability, meaning you must be able to produce all logs of denied access attempts and verifications.

Attorneys from ARROWS advokátní kancelář have extensive experience representing clients in licensing proceedings in the Czech Republic. We will help you prepare documentation for changes to the game plan, notifications of changes in technical equipment, or guide you through the process of obtaining a new licence.

FAQ – Most common legal questions on geo-blocking for online gambling

1. Is my gambling website required to implement geo-blocking even if it has low traffic?
Yes. The Czech Gambling Act does not distinguish by size. The obligations to comply with the territorial scope of the licence and to prevent unauthorised persons from playing apply to every licence holder from day one of operations.

2. Which specific countries must I block?
You must block all countries where you do not hold a licence and whose legislation prohibits the provision of gambling services from abroad.

3. What happens if a player from a blocked country accesses my platform via a VPN?
The regulator assesses whether you have taken “reasonable measures”. If you have a VPN detection system and require strong identity verification, your position is much stronger than if you only have basic IP checks.

4. Is geo-blocking part of GDPR obligations?
Not directly, but it is related. Processing location data for the purpose of complying with a legal obligation is compatible with GDPR; however, you must have your Privacy Policy set up correctly.

5. What penalties do I face for breaching geo-blocking rules?
You face a fine of up to CZK 50,000,000 under the Czech Gambling Act, and potentially a ban on activity. You also risk sanctions in the country you unlawfully entered, in the form of fines imposed by local regulators.

6. Can I outsource geo-blocking entirely to a third party?
Technically yes, but legally you remain responsible as the licence holder under Czech law. The contract with the supplier must be precise and include warranties and contractual penalties, which we can help you with at office@arws.cz.
