Poland’s Finance Ministry gambling register tells you which domains providers must block. Our checks on 12 and 14 November 2026 found different treatment of names under a listed domain: Play also blocked www., while Netia blocked every subdomain we tried. Orange and T-Mobile home lines and Plus mobile lines showed blocks on the exact listed names, but no register block on the tested subdomains.

What is Poland’s gambling register, and who adds domains?
The Finance Minister keeps the public Rejestr domen służących do oferowania gier hazardowych niezgodnie z ustawą at hazard.mf.gov.pl. It covers domains used to offer, advertise or promote unlawful gambling accessible from Poland. Entries are made officially after approval by the minister or a designated tax authority, rather than by internet providers.

Our download on 14 November 2026 contained 59,849 active entries. That is a count of register entries, not gambling businesses or confirmed blocks at every provider.

What is the 48-hour rule, and what is the fine?
Internet access providers must block a listed name in their DNS, the system that turns a domain into a server address, within 48 hours of entry. They must direct connections to the Ministry’s notice and restore access within 48 hours of removal. Failure to meet these duties can bring a fine of up to PLN 250,000.

How can you search or download the register?
Search the exact hostname on the register website, including www. if you use it. For a program, the public XML API supplies current entries and their entry dates. Removed entries are absent from that download; it is not a history of removals.
GET /api/Register: the full current register.GET /api/Register/ModificationDate: the time of the last register change.
Both endpoints are on https://hazard.mf.gov.pl. The Ministry’s technical specification recommends a full download every two hours. Keep dated copies if you need to compare changes, and use the register archive when investigating a removal.

Which names did each Polish provider block?
Our samples showed three patterns: exact-name blocking, added blocking of www., and blocking of other names under the listed domain. “No block observed” means no register block appeared in that sample; the website could still fail or refuse the request.
| Provider and connection | Exact listed name | Unlisted www. | Other unlisted subdomains |
|---|---|---|---|
| Orange, home | Block observed | No block observed | No block observed on random name or m. |
| T-Mobile, home | Block observed | No block observed | No block observed on random name or m. |
| Plus, mobile | Block observed | No block observed | No block observed on random name or m. |
| Play, home and mobile | Block observed | Block observed | No block observed on random name or m. |
| Netia, home | Block observed | Block observed | Every tested random name and m. blocked |
| Orange and T-Mobile, mobile | Too few usable lines to establish how they apply the register | ||

How much did we measure?
On 12 November we compared two domains listed on 6 November with unlisted www. and random subdomains that existed in public DNS. Play blocked the www. versions on 12 of 12 line observations across home and mobile checks. Netia sent all tested www. and random names to the notice server: 12 line observations across five checks, two of which had only one or two lines.
One Orange home check blocked the listed name on three of four lines, so even an observed pattern was not uniform. One Play home listed-name check had only two lines, below the minimum for a block verdict; the other had three of three. On 14 November, a separate m. check under a domain listed on 10 November reached the server on three of three Play home lines and three of three Play mobile lines. Netia blocked it on three of three.
Orange and T-Mobile mobile checks remained inconclusive: too few lines or failed connections. We did not test Vectra or INEA in this comparison. These are dated samples, not a test of the whole register or every subscriber. Results have not been calibrated; a DNS block is reported as “likely” at most.

What does a blocked visitor see?
The blocks observed in our comparison used provider DNS to return the Ministry’s notice-server address. The official notice says access has been blocked because the domain is in the register. However, a visitor using HTTPS may see a connection error instead: an OONI measurement on Plus on 4 November 2026 received the Ministry’s address, then timed out connecting to it over HTTPS.

Can an affiliate’s tracker or landing page be affected?
A hostname can be absent from the register and still fall under a provider’s block on its parent domain. Our Netia observations make that a risk for an affiliate’s tracker or landing page under a listed domain. At Play we observed this for www., but not for the tested random names or m.. This is an inference from the samples, not evidence that every tracker is affected.
For a compliance check, search both your full hostname and its parent names, then test the actual URL. See the broader guide for gambling operators and Poland overview.

What if the listing is wrong, or a block remains after removal?
A domain rights holder can object to the Finance Minister within two months of entry, giving identifying details and reasons for removal. The minister must decide within 14 days of receiving the objection.

For a continuing block, save the removal evidence and time, exact hostname, provider, home or mobile connection, and dated check result. After the 48-hour removal deadline, send that evidence to the affected provider’s support and ask it to investigate. Check parent names too: removal of one name does not establish that every related entry has gone.
