Casino Licence Numbers Decoded: Dates Hidden in Digits

New casinos rarely disclose their age. However, a licence number may disclose that. While evaluating the 20 casinos on our new casinos list, we used number formats to date two sites that do not disclose their launch dates, and also to catch a third whose digits contradict what the site states. This guide will provide you all the formats we have on our list, from the most verbose to the completely mute.

The information hierarchy

Not all licence numbers include the same detail. From the most to least detail, a casino's licence number may provide you with:

1. A stated issue date you can verify - printed on the site and confirmed at the regulator. The gold standard.
2. A register entry - the regulator's own listing with dates, even when the site says nothing.
3. A date stamp inside the number - the paperwork dates itself, if you know the format.
4. A plain serial - a number that proves nothing by itself and must be looked up.
5. A claim with no number - the bottom of the pile. One casino on our roster claims a licence and prints no number anywhere; its own seal validates as INVALID.

All the points below relate to level two and three details: what the register adds and what the numbers already reveal.

Malta: MGA/B2C/serial/year

When it comes to Malta Gaming Authority numbers, the shape is consistent: MGA/B2C/1079/2025. Three fields are relevant.

The class marker. B2C represents a player-facing licence. B2B represents a service-facing licence. You will find them both on the same page: SpinSkull's footer holds its MGA/B2C/1118/2025, while its sportsbook is run via a supplier holding MGA/B2B/875/2021. A casino showing a B2B number as evidence that it can take your deposit is showing you the wrong paperwork.

The year tag is a vintage, and it is a floor for the brand's age. Beazt's number ends with 2025 and was issued on the 10th of September, 2025. SpinSkull's tag also ends with 2025 and was issued on the 29th of January, 2026. So, in this case, the date of the tag is the vintage and the specific date of printing/issuing is either available on the site or in the register (where Malta publishes them).

The type line is shown beside the number. Malta licences grant the right to offer certain game types: SpinSkull prints both Type 1 (games of chance against the house) and Type 2 (fixed-odds betting). If a Malta-licensed site offers a product that is not covered by the printed types on the site, that should be a red flag before a deposit is made.

Anjouan: the date stamp in ALSI numbers

Of the numbers on our list, Anjouan Gaming Board numbers are the most verbose: ALSI-YYYYMMNNN-FI#. The middle block is a date stamp - year, month, and a sequential number for that month.

We did not guess this; a casino confirmed it in writing. WinSpin's terms state that "the license ALSI-202509006 was issued on 16/09/2025." The "202509" block means September 2025 and once the format is set, the rest of the roster falls into place:

• Bitguruz: ALSI-202505027 reads as May 2025. The site publishes no launch date; the number is the only calendar it carries, and its seal validates live.
• Thrill: ALSI-202506019 reads as June 2025, which agrees with the site's own anniversary page placing the launch in August 2025. Paperwork first, doors open two months later - a coherent story.
• Bombastic: ALSI-202511022 reads as November 2025 - on a site whose browser title claims "Since 2022". The digits and the marketing cannot both be right, and the digits are the ones printed on a licence claim. Its seal, for the record, validates as INVALID.

Another example from WinSpin: footer prints one number (ALSI-202601043) while terms state another (ALSI-202509006). Two numbers on one website is not necessarily an indication of fraudulent activity (licences can be renewed) however, you should take note of this because only one of them can be the active licence. Anjouan runs a seal validator on its own domain and no browsable public registry, so the seal click is the only independent check available.

Nevis: a number that names its owner

The newest format on our roster is also the densest. OreonBet's licence reads LIC-B2C202607C635660001 and every block can be decoded as:

• LIC-B2C - a player-facing licence, same class logic as Malta's marker.
• 202607 - July 2026, the grant vintage. The public register lists an expiry of 12 July 2027, which back-dates a one-year licence to a July 2026 grant. Digits and register agree.
• C63566 - the operator's own company registration number. LEUATAR NET LTD is registered as C63566, and the licence number carries it. The number literally names its owner.
• 0001 - a sequence number.

The Nevis register is a public and filterable table and the strongest lookup experience of any of the regulators on our roster and OreonBet's row is Active. When a format incorporates the operator's registration, verifying takes just a few seconds. The company in the footer and the company in the number must match.

Curacao: the OGL vintage

New-regime Curacao numbers - OGL/2024/589/0556 and kin - only have a space for a year. These numbers date the operator's paperwork associated with the new law. Since each licence belongs to the operator and each domain gets its own certificate, the same number can work for one brand and answer Not Found for its sister. That mechanism, and the three dead cert links we documented, has its own guide: how to check a Curacao licence.

Numbers that tell you nothing - and what to do then

Plain serial numbers are not necessarily bad, as they simply shift the burden to the registrar.

Kahnawake numbers are plain serial numbers. SlotRave has No. 00910. While the serial number is of no consequence, the date of issuance of the number by the registrar, 1 December 2022, is of notable relevance. This date was prior to the creation of the brand, and was the permit date for the operator, and is how we came across a casino representing itself as a newly created entity and operating on 2022 paperwork. SlotRave is thus located in our archive, rather than being listed in ranking.

Tobique numbers are also plain serials. CoinCasino claims No. 0000163. The validator provided by the commission answered that the site is NOT licensed. A serial number along with a failed validation is worse than no claim, as it shows the casino knows what real paperwork looks like.

No number at all is the floor. Claiming an Anjouan licence, Oxibet has no number anywhere on the site and its seal answers INVALID. There is nothing to decipher and nothing to look up. That is your answer.

How to use this in practice

1. Read the stamp. Find the number in the footer or terms and pull the date fields out: the MGA and OGL year tags, the ALSI year-month block, the Nevis grant block.
2. Cross-check the story. Compare the stamp against everything the site claims about itself - a "Since 2022" banner over 2025 paperwork, or an anniversary page that fits the licence month, both tell you something.
3. Then verify. The digits are still just a claim until the regulator answers. Click the seal, open the register, and treat any mismatch between printed number and register answer as the finding it is.

Licence number FAQ

Can you tell when a casino launched from its licence number?

Dating stamped paperwork allows us to set a brand's minimum age. A year and month stamp is present on Anjouan ALSI numbers, year tags come on Malta and Curacao numbers, and on Nevis numbers there is a year-month grant block. As it usually takes several weeks or even months for the site to launch after the licence is granted, consider the stamp as being 'not older than' this date, and check the register for the actual dates.

What does B2C mean in a licence number?

B2C stands for a licence to serve players. B2B stands for a licence to supply other businesses, such as game or sportsbook providers. Both licences appear on Malta and Nevis formats. A casino should have a B2C licence, as a B2B licence on a supplier's webpage does not give any rights to the casino to take players' money.

Is a printed licence number proof a casino is licensed?

No. Printing a number is a claim. A regulator's validator or the register answering is the proof. One of our listed casinos prints a full Anjouan number with the regulator's validator answering NOT Licensed. Another prints a Tobique serial with the same result, and three print Curacao numbers whose certificate links answer Not Found.

Why does one casino show two different licence numbers?

Exactly this was observed on WinSpin: one number in the footer, an older number with an explicit issue date in the terms. Renewals and re-issues happen, and documents lag. This is worth consideration because only one number can be in force, and it can give us an idea about how carefully the site maintains its own legal text.

Play responsibly

Gambling is entertainment with a cost, never a way to make money. Decoding paperwork tells you who is behind a casino and how old it is; it does not change the odds of a single game. Set a ceiling before you deposit anywhere, and treat every bonus as spending, not income.
