UKGC warns casinos as 25% of player complaints tied to ID checks
Regulator tells operators to fix verification failings after players blocked from withdrawals despite passing registration checks.
The UK Gambling Commission has issued a formal warning to online casino operators after finding that more than a quarter of all complaints received by its Contact Centre relate to identity verification failures.
In a blog post published on 12 August 2026, the regulator said it had identified “a number of instances” where licensees were not collecting sufficient information from customers at registration to meet the requirements of Licence Condition 17, which covers identity verification.
As a result, some customers are being asked to provide additional documents when they attempt to withdraw funds, despite having already completed the operator’s sign-up process. The Commission said disputes over identity verification are among the most common complaints referred to alternative dispute resolution providers.
The warning follows analysis of the Commission’s financial risk assessments pilot, carried out between 2024 and 2025, which revealed that failures during customer onboarding were a key reason why some customers could not be matched to credit reference agency records.
Helen Rhodes, Director of Major Policy Projects and Evaluation, and Sarah Webster, Senior Policy Officer, wrote that deficiencies in ID verification practices had “undermined the pilot” and “worsened consumer experience by increasing friction, complaints and regulatory risks.”
The regulator raised specific concerns over operators’ reliance on “fuzzy matching” when using third-party identity verification services. This process can allow information that is similar, but not an exact match, to be accepted during verification, which the Commission warned could lead to customers being incorrectly verified despite discrepancies in their name or address.
Other issues identified included operators accepting incomplete or inaccurate information at registration, such as customers using an initial rather than their full name, a nickname, a middle name instead of their forename, or providing a commercial rather than residential address.
The Commission said these practices created mismatches with records held by external databases, including GAMSTOP, and warned this could undermine the effectiveness of self-exclusion protections.
Licensed operators have been urged to collect complete and accurate information at registration and to address any unresolved identity concerns before customers are permitted to deposit or play, rather than waiting until withdrawal.
What it means for players
If you’ve ever been asked for extra ID documents when trying to withdraw—despite sailing through registration—this is why the regulator has stepped in.
Casinos are supposed to verify your identity properly when you sign up, not spring surprise document requests on you weeks later when you’re trying to cash out. The Commission is now telling operators to tighten up onboarding checks and stop relying on shortcuts that let incomplete or mismatched details slip through.
For players, this should mean fewer withdrawal delays in future, though it may also mean slightly more friction at the registration stage as casinos ask for fuller details upfront. Make sure you provide your full legal name, current residential address, and accurate date of birth when signing up—nicknames, initials, or old addresses can cause verification mismatches that lock you out of GAMSTOP protection or slow down withdrawals later.
If you’re currently stuck in a withdrawal dispute over ID, you can escalate to an alternative dispute resolution service if the casino won’t budge. The UKGC doesn’t handle individual complaints, but ADR providers like IBAS and ECOGRA can step in and mediate.
