Almost every licensed casino displays a licence number somewhere in its footer, but most players scroll straight past it without knowing what the string of characters actually represents or how to use it.
What a Licence Number Identifies
A licence number identifies a specific authorisation granted to a specific legal entity by a specific regulator — it isn’t a brand name, and it isn’t unique to a casino’s public-facing identity. Many casino brands operate under a parent company, and the licence number will typically correspond to that legal entity’s name, not the marketing name shown on the homepage.
How Formats Differ Between Regulators
Different regulators structure their licence numbers differently. A Gibraltar licence number is tied to the specific licence category granted under the Gambling Act 2025, while a UK Gambling Commission number follows its own separate numbering and account-based reference system entirely distinct from Gibraltar’s. A dual-licensed operator will display two separate numbers, from two separate regulators, and both should be checkable independently.
Tracing a Licence Number
To actually verify a number rather than just note it, search the regulator’s own public register using the exact number and the legal entity name shown alongside it, not the casino’s brand name. A number that resolves correctly, matches the entity name, and shows an active status confirms the licence is genuine and current.
What a Mismatch Means
If a licence number returns a different company than the one operating the casino, shows an expired or suspended status, or doesn’t resolve on the register at all, treat that as a serious issue rather than a clerical error.
