Why most casinos still show a /JAZ number
Under the system that ran until the 2024 LOK reform, Curaçao did not license online operators one by one. Instead it granted a small number of master licenses to private companies, who in turn issued sub-licenses to the actual casinos and sportsbooks. An operator didn't get its own license number — it operated under its master licensor's number.
That number ends in /JAZ — a reference to the Minister of Justice (Justitie), under whose authority the old offshore-gaming ordinance was administered. Because that model ran for two decades, the overwhelming majority of live Curaçao casinos still display a /JAZ number in their footer, even as the regime moves to the new OGL format.
The four master licensors
There were only four. If a casino cites a /JAZ number, it almost certainly traces back to one of these:
Cyberluck Curaçao N.V.
Curaçao eGaming (CEG)
Antillephone N.V.
one of the most widely cited master numbers
Curaçao Interactive Licensing N.V.
CIL
Gaming Curaçao
GC
A footer that reads "licensed and regulated … under license 1668/JAZ" means the casino held a sub-license under Cyberluck Curaçao N.V. — not that Cyberluck is the casino. Seeing the same number on dozens of unrelated sites is normal: they all sub-licensed from the same master.
How to read a /JAZ number
The format is simpler than the new one — usually just the master license number, the /JAZ suffix, and sometimes a sub-license reference appended (for example 8048/JAZ2020-013). Unlike the new OGL numbers, a /JAZ number on its own tells you which master a site sub-licensed from — but not much about the individual operator's standing.
Key limit: a /JAZ number identifies the master licensor, not a verified record for the specific casino. That is exactly the gap the 2024 reform set out to close by licensing operators directly.
What's replacing them
Since 15 November 2023 the regulator has issued online licenses directly, using the OGL/YYYY/NNN/NNNN format instead of the master/sub-license chain. The old /JAZ master licenses are being wound down as operators move onto direct licenses under the Curaçao Gaming Authority. For a while you will see both formats in the wild — a legacy /JAZ number on older pages, an OGL number on newly licensed ones. Read the new format in the license-number decoder.
Checking a site that still shows /JAZ
A /JAZ number is not a red flag by itself — the model was legitimate for twenty years. But because it points at a master rather than a verified operator record, it proves less than people assume. Treat it as a starting point, not a guarantee, and confirm current standing the same way you would for any license: see how to verify a license, and check whether the operator has moved to a direct OGL license yet.
The authority and its published register are the source of truth for both old and new licenses — cga.cw.
Frequently asked
Is a /JAZ license number a red flag?
Not on its own. The master / sub-license model was legitimate for two decades, so a /JAZ number is normal on older sites. It simply proves less than people assume — it identifies the master licensor, not a verified record for the specific operator.
Why do unrelated casinos show the same /JAZ number?
Because they all sub-licensed from the same master. Seeing 1668/JAZ or 8048/JAZ on dozens of different sites just means each one operated under that master licensor — it does not mean the sites are connected or owned by the same company.
Will /JAZ numbers disappear?
Gradually. Since 15 November 2023 the authority has issued direct OGL licenses, and the old master licenses are being wound down as operators migrate. Expect to see both formats during the transition, and check whether a site has moved to a direct OGL license yet.
