Every UK-licensed online casino displays a licence number, usually in the footer of its website. That string of digits, issued by the Gambling Commission, is not just a formality. It is the primary way a player can verify that a site is authorised to offer real-money gambling in Great Britain.
A licence number also reveals the type of gambling the operator is permitted to run. A single company might hold separate numbers for casino games, betting, and bingo. Players who also browse casinos not on GamStop UK sometimes compare how licence numbers work because those sites operate under different regulators and do not display a Gambling Commission number at all.
Where to Find the Licence Number and How to Check It
The Typical Location on a Casino Website
Scroll to the very bottom of the homepage, and you will usually see a small block of text listing the operator’s company name, its registered address, and the licence number. The number is often preceded by the words “Licensed and regulated by the Gambling Commission” and may be hyperlinked. Clicking it should take you directly to the operator’s entry on the public register.
Some sites place the number inside a dedicated “Responsible Gambling” or “About Us” page instead. If you cannot find it within a few seconds, that is a warning sign. Legitimate operators make the number easy to locate because they know it is a basic trust signal for new customers.
Using the Gambling Commission’s Public Register
The official register is free to search. Enter the licence number or the company name, and you will see the licence status, the types of gambling covered, any sanctions, and the domains the operator is allowed to use. A number that returns no result, or a status marked “suspended” or “revoked,” means the site has no valid permission to trade in the UK.
Always cross-reference the domain name listed on the register with the website you are visiting. A common trick involves copying a legitimate number onto an unlicensed clone site. If the register shows a different URL, the site is fraudulent, even if the design looks authentic.
What the Licence Number Reveals About the Operator
Type of Activity and Operating Licence Categories
A single limited company can hold multiple operating licences, and each has its own reference. The number you see on a slots site corresponds to a “casino” operating licence under the Gambling Act 2005. The same parent company might run a sportsbook under a separate “general betting” licence number.
When you look up a licence, the register breaks down the permissions into categories. For a typical slot site, you would expect to see entries such as “Casino” and sometimes “Bingo.” If you only see a “Pool betting” licence on a site offering roulette, the operator is acting outside its permissions.
Licence Conditions and Compliance History
The register entry also lists any individual conditions the Commission has attached to the licence. These can include extra reporting requirements, restrictions on payment methods, or rules about customer interaction. A licence with several additional conditions often indicates a past compliance failure that the regulator is monitoring closely.
You can also see a timeline of regulatory decisions, such as fines, warnings, or licence suspensions. A clean record over many years suggests a stable operation, while a series of recent sanctions points to ongoing risk.
Licence Numbers Versus Foreign Regulators
How UK Numbers Differ from MGA or Curacao Licences
The Gambling Commission format is a unique identifier tied to a specific legal entity and a defined set of activities. A Malta Gaming Authority licence, for instance, includes a prefix such as MGA/B2C/ followed by a reference number, and it covers multiple product types under one umbrella licence. Curacao-licensed sites often display a single master licence number that belongs to a third-party provider, not the operator itself.
This structural difference affects what you can verify. With a UK number, you check the exact company and domain. With a Curacao master licence, you may only see the name of the licence holder, which could be a B2B company that sub-licences to dozens of unrelated casino brands.
Why a Licence Number Is Only Part of the Picture
A valid UK licence confirms that the operator meets minimum standards for player funds segregation, fairness testing, and anti-money-laundering procedures. It does not guarantee that disputes will be resolved in a player’s favour, nor does it rate the quality of customer support or withdrawal speed.
- A licence number confirms authorisation for specific gambling activities in Great Britain.
- The register shows the approved domain names, so you can spot clone sites.
- Sanctions and individual conditions are listed publicly and reveal compliance history.
- A foreign licence number may reference a different legal entity, making verification harder.
When a Licence Number Raises a Red Flag
Missing, Copied, or Outdated Numbers
A missing licence number is the most obvious red flag, but a copied number can be harder to spot. Fraudsters sometimes paste a real number into the footer of a fake site. When you look it up, the register points to a different domain belonging to a legitimate operator who has no connection to the clone.
An outdated number can also signal trouble. If a company’s licence was revoked six months ago but the number still appears on a live site, the operator is trading illegally. The Commission publishes updates promptly, so any discrepancy is a serious warning.
Multiple Brands Under One Number
Some UK operators run several casino brands under a single operating licence, and this is legal as long as each domain is listed on the register. However, if a brand is not listed under the approved domains, it is not covered by that licence, even if it shares the same owner and displays the same number. Checking the domain list is just as important as verifying the number.
FAQ
Is a licence number the same as a company registration number?
No. The licence number is issued by the Gambling Commission and authorises gambling activities. A company registration number comes from Companies House and simply confirms the business exists as a legal entity.
Can a casino lose its licence number after I have signed up?
Yes. If the Commission suspends or revokes a licence, the operator must stop trading immediately. The regulator typically requires the company to return outstanding customer funds, but the process can take time.
What should I do if the licence number on a site does not match the register?
Do not deposit money. Report the site to the Gambling Commission through its online reporting form. Include the URL and a screenshot of the footer showing the incorrect number.
