What does a licence number prove, and which company stands behind the sign?
21 of the 28 casinos publish a licence number, and those 21 numbers hold only 20 distinct values. The certificate is written on the company, not on the brand.
Who is the licence written on — the company or the sign?
Seven of the 28 publish no number at all: BC.Game, BetPanda.io, Coins.Game, CryptoLeo, Katsubet, Lucky Block and Vave. Of the 21 that do, only 20 are distinct, because King Billy Casino and Woo Casino state exactly the same string, 8048/JAZ2020-013.
That is not an error in the table. Five of the casinos name Dama N.V. as their operator or former operator: 7Bit Casino, Katsubet, King Billy Casino, Winz.io and Woo Casino. One company can run several signs, and a sign is changed more easily than a company.
Two sites with different colours, a different mascot and a different bonus page can therefore share a legal entity, a payment flow and a support routine.
What does a Curaçao certificate actually say?
The Curaçao Gaming Authority runs a certificate portal that is searched by domain, not by brand. A certificate that comes back names the domain, the company operating it, that company's Curaçao registration number, the licence number, the law it rests on — the Landsverordening op de kansspelen, P.B. 2024, no. 157 — and the date the licence was granted along with its current status.
That makes a certificate a different object from a logo in a footer. An image cannot be looked up; a domain can.
Here is what a hit looks like in practice: 7bitcasino.com answers with OGL/2024/1307/0748, company Scores55 Tech B.V., company number 162990, granted 16 July 2024, status Active. Katsubet answers with exactly the same certificate. Two signs, one certificate.
Which five answers can the register give, and how common is each?
A hundred domains from the shared library were put to that portal. Thirty-seven answered Active and six answered Revoked. Three returned the statement that the domain has been removed from the registry, which is an answer of its own and neither of the first two.
Forty-one domains were not in the register at all, and thirteen returned nothing. “Not found” is not the same as “unlicensed” — it means that this domain was not in that register when the question was asked.
Among the 28 here, luckyblock.com received the removal answer, while bc.game and bets.io came back Revoked. These are readings of a register, not verdicts on companies.
Why do five of the numbers look completely different?
The portal issues certificates in the form OGL/year/serial, but five rows in the table give a number in the older Antillephone form: BitSler 8048/JAZ, King Billy Casino 8048/JAZ2020-013, Woo Casino 8048/JAZ2020-013, Winz.io 8048/JAZ2020-13 and Rocketpot 1668/JAZ.
Two of them differ by a single digit. King Billy Casino and Woo Casino write 8048/JAZ2020-013, Winz.io writes 8048/JAZ2020-13 — the same master licence, a different spelling, and a search string that does not match the other.
A number in the older form cannot be looked up in the certificate portal the way an OGL number can. That does not make the number false, but it does make it harder to check, and the difference is the part that matters to a reader.
Where does the number on the site disagree with the number in the register?
7Bit Casino states OGL/2023/174/0082 on its own page with Dama N.V. as operator, while the portal answers for the domain 7bitcasino.com with OGL/2024/1307/0748 and Scores55 Tech B.V. That is two different numbers and two different companies for one domain.
mBit Casino states the same OGL/2024/1307/0748 that 7Bit Casino and Katsubet share, yet the portal returns nothing for mbitcasino.com. Three signs point at one certificate, and only two of the domains answer with it.
BitSler prints 8048/JAZ in its licence line, but the portal answers OGL/2024/930/0387 with Oyine N.V., company number 144430. Vave prints no number at all; on a re-reading of 2 September 2026 the portal answered OGL/2024/1676/0905 with Latcas B.V. Of the two sources, only the register can be looked up, which is why it is the one quoted here when the two disagree. Wild.io is the mirror image: its own pages print the Anjouan number ALSI-202504044-FI2 held by Stack Gaming Ltd, while the Curaçao portal answers OGL/2024/210/0198 with Nonce Gaming B.V., company 161858, active since 14 April 2025. Both records are live at the same time and they belong to two different companies — two licences, not a move from one to the other. Lucky Block is the opposite case: the Curaçao portal reports luckyblock.com as removed from the registry, the Anjouan register holds no entry, and its own legal pages could not be read, so the table carries neither a number nor a holder.
What does the Anjouan register give that Curaçao's does not?
Six of the 28 name Anjouan, and three of them publish the number: 1xBit ALSI-202409027-FI2, Bets.io ALSI-202410047-FI2 and FortuneJack ALSI-202411021-FI1. The other three name the jurisdiction with no number.
The Anjouan public register holds 39 of the library's brands under 34 distinct numbers, and unlike a Curaçao certificate it prints both an issue date and an expiry date. An expiry date is the only field in the whole body of material that says anything about the future.
One number carries five signs: ALSI-202508056-FI2, issued 25 August 2025 and valid to 24 August 2027, is written on Novatrix SRL and covers Oshi Casino, PlayAmo, Slotum, Bitkingz and Winz.io — which on its own licence line prints an old-form Curaçao number instead.
What does Costa Rica on the licence line mean?
One of the 28, BetPanda.io, gives Costa Rica as its licensing country with Star Bright Media S.R.L. as the company. Costa Rica has no gambling authority that issues gambling licences; a company registers like any other company and operates without a specific permit.
The consequence is concrete: there is no gambling register in which to look the domain up. Where Curaçao answers with a certificate and Anjouan with a register entry, Costa Rica answers with a company registration, and a company registration tells you what the company is called, not what it is allowed to do.
Costa Rica also appears as the home of the companies behind two other rows — FortuneJack's PlayWave SRL and Vave's Chestoption S.R.L. — which nevertheless give a different jurisdiction on the licence line. Country of incorporation and country of licence are two fields, not one.
What does the number prove in the end?
A number shows that some company is registered with some authority somewhere, and that the authority holds an entry which can be looked up. It says nothing about which body decides a dispute, what deadline the operator has to pay, or what happens to a balance if the site closes.
It says nothing about Nordic supervision either. None of the 28 is licensed inside the EEA, and that single fact is what decides how a win is taxed — read what applies on the Swedish market and the three verification policy types.
The next step is to compare what really separates the rows: the withdrawal caps and the thirteen published amounts, the full table of the 28 and the read-through casino by casino.
