How to Find Every Casino Listed Under One UKGC Licence

What Can One UKGC Account Tell You?

A UK Gambling Commission account number identifies a gambling business within the Commission's licensing system.

That business record can contain more than the legal company name.

The Public Register also records information including declared trading names, domain names, licence status and regulatory actions.

This makes the account number one of the most useful starting points for finding casino brands and domains that sit within the same licensed operator environment.

However, the register should be read carefully. A domain appearing within the same record does not automatically mean every brand has the same ownership history, player account system or commercial structure.

Step 1: Find the Casino's UKGC Account Number

For a Great Britain-facing remote casino, start with the licensing statement on the casino website.

UK Gambling Commission licence condition 8.1.1 requires covered remote gambling operators to display:

• a statement that they are licensed and regulated by the Gambling Commission
• their account number
• a link to their current licensed status on the Commission's website

The account number is particularly useful because brand names can change while the licensed business behind them may remain the same.

For example, the visible casino name might be a marketing or trading name rather than the legal company name recorded as the licence holder.

Step 2: Search the UKGC Public Register

Open the UK Gambling Commission's Register of gambling businesses.

The register currently allows searches using:

• business name
• trading name
• domain name
• account number

If you already know the account number, that is normally the cleanest route because it points directly towards the relevant business record rather than depending on brand-name spelling.

You can also start with a domain if the account number is not immediately visible.

Step 3: Check the Domain Names

Once you have identified the correct operator record, look at the declared domain names associated with that business.

This is often the most useful section when researching casino networks or sister sites because multiple consumer-facing domains can sit underneath one operator record.

For each domain, record:

• the exact domain name
• its current UKGC status
• the operator account it belongs to
• whether the brand currently appears to be live

Do not assume that every domain in the record is necessarily a current casino brand. Historical and inactive domains can remain useful for research but should not automatically be presented as current sister sites.

Step 4: Read Active, Inactive and White Label Status

The UKGC business register distinguishes between several domain statuses.

For domain names, the register currently uses:

• Active
• Inactive
• White label

These labels matter because a list of domains without status information can make a casino network look very different from its current reality.

Active

An Active domain is recorded as active within the operator's current register data.

Inactive

An Inactive domain may represent a domain that is no longer being used in the same way, a closed brand or a historical relationship that requires further checking.

White label

A White label domain indicates a different type of relationship and should be classified separately from a straightforward operator-owned brand.

This distinction is one reason A2Z does not publish a simple undifferentiated list of every domain found under an operator account.

Step 5: Check Trading Names

Domains are only one part of the record.

The UKGC also records declared trading names, which can help connect consumer-facing brands with the legal business behind them.

A trading name may be useful where:

• the casino brand name differs from the legal operator name
• several brands operate within the same company
• a brand has changed domains
• historical operator relationships need to be reconstructed

The register identifies trading names as Active or Inactive.

Combining trading names with domain records often gives a more complete picture than looking at either dataset alone.

What the Register Does Not Prove

The UKGC register is a powerful regulatory source, but it should not be asked to answer questions it does not establish by itself.

For example, finding two domains under one operator account does not automatically prove that:

• the brands use the same player login
• they share one wallet or balance
• their bonuses are identical
• they use the same platform
• their ownership history has always been the same
• both domains are currently active consumer brands

The Commission also notes that domain names and trading names are provided by the gambling business itself and that it cannot guarantee the accuracy of information supplied by third parties.

That is why current website checks and additional operator or corporate research may still be necessary.

How A2Z Uses UKGC Records

A2Z uses the operator account as one layer of a broader relationship check.

A typical research path is:

1. Brand — identify the consumer-facing casino.
2. Domain — record its current website address.
3. Operator — identify the legal gambling business.
4. UKGC account — confirm the regulatory record.
5. Domain status — distinguish Active, Inactive and White label entries.
6. Trading names — identify additional declared brand identities.
7. Ownership and platform — research separately where relevant.

This approach helps distinguish a real regulatory connection from a looser relationship based only on shared design, payments or technology.
