This is the most useful skill on the whole site. Once you can check a licence yourself, you never have to take a casino, or a review site, at its word again. It takes under a minute, it costs nothing, and it works the same way for every Estonian-licensed operator. Below is the full process, followed by a worked example and the mistakes to watch for.

Step 1: Find the licence number
Open the casino site and scroll to the footer. Licensed Estonian operators print their licence details there, usually near the company name and registry code. You are looking for a code in the format HKT###### or HKL######, for example HKT000060 or HKL000373. The same details often appear on the site's Terms, About or Responsible Gaming pages.
While you are there, note two more things: the legal entity name (the company, often ending in OÜ, AS, Ltd or LTD) and the registry code (an eight digit number next to a marker like "Reg No" or "registrikood"). You will use these to confirm the licence belongs to the right company. Write all three down: the licence number, the company name, and the registry code.
Step 2: Open the Estonian register
There are two official routes, and it is worth knowing both because they answer slightly different questions.
- The EMTA operator list. The Tax and Customs Board publishes a public list of licensed gambling operators, organised by category (games of chance online, organisers of toto and others). This shows you the operator, its brands and the domains listed under each licence. Use it to answer: is this company licensed, and is this exact domain listed under it?
- The MTR register of economic activities (mtr.ttja.ee). This is the authoritative record for a given legal entity: its registry code, address, board members, and the exact licence numbers with their type, status and dates. Use it to answer: does this specific HKT/HKL number exist, is it active, and who holds it?
You do not need both every time. For a quick check the operator list is usually enough; when something looks off, the MTR entry is where you confirm the detail.
Step 3: Match the licence to the company
This is the step most people skip, and it is the one that matters. A licence number on its own is not enough, because a number can be real while still belonging to a different company than the one taking your money. Confirm all three of these line up:
- The HKT/HKL number from the footer exists in the register.
- It is held by the same legal entity named in the footer. Check the registry code, not just the name, because names can be similar.
- The licence is active, and the domain you are on is listed under that operator.
If the licence exists but is held by a different company, or the domain is not among those listed, treat that as a red flag and look closer. This is exactly how some brands route players from a licensed domain to an unlicensed one.
A worked example
Take a listing from this directory, HappySpins. Its footer names an Estonian company, Damagi Marketing Solutions Ltd, with the licence numbers HKT000060 and HKL000373 and a registry code. You look the company up in the register: the code matches, the HKT and HKL numbers appear under it, and the licence is active. That is a clean verification. Every casino page in this directory, for example Winnerz, shows the same three facts (legal entity, registry code, licence numbers) with a direct link to the register, so you can repeat the check in seconds rather than trust our summary.
What a clean verification looks like
A straightforward, licensed operator will show you a legal entity, a registry code and HKT/HKL numbers in the footer; those numbers will appear in the register under that same entity; the licence will be active; and your domain will be on the list. When all four are true, the site is licensed in Estonia. When any one fails, you have found something worth understanding before you deposit.
Step 4: Watch for multi-licence brands
Some brands hold an Estonian licence through one company and other licences (Malta, Curacao, Kahnawake, Anjouan) through separate companies, then route players to whichever applies to them by location. The Estonian licence only covers the Estonian company and its domains. If you were sent to a different domain, or a different company is named at checkout, the Estonian licence you verified may not apply to you. Check the licence on the exact domain you are actually playing on. We explain this pattern in detail, with a real example, in how one brand holds several licences.
Common red flags
- No number at all. If a site aimed at Estonian or Finnish players cannot show an HKT/HKL number that matches a named company, it is not operating under an Estonian licence, whatever else it claims.
- Number without a company. A licence code with no legal entity or registry code beside it cannot be matched, which defeats the point of a verifiable licence.
- Mismatch at checkout. The footer names one company but the payment page or account terms name another. That second company is the one you are actually contracting with.
- Wrong domain. The licence is real but the specific domain you are on is not listed under that operator.
Why this matters
The value of an Estonian licence, for a player, is that it is verifiable. You do not have to trust a badge image or a five-star review. You take a number, look it up, and confirm it yourself. That is the whole basis of this directory, and it is the one thing competitors that invent brands and top-lists cannot offer. If you want the background first, read what an EMTA licence is; otherwise, pick any casino here and try the check yourself.
Take the HKT/HKL number from a casino footer and look it up in the register. Our step-by-step guide shows how.
