Most UK-licensed gambling platforms restrict players to one account per person. This rule applies across all game types, including online casino games, live casino tables, and online slots.
The one-account policy is not arbitrary. It is a regulatory requirement rooted in consumer protection, fairness, and anti-fraud controls established by the UK Gambling Commission. Maintaining a single account allows operators to apply responsible gambling safeguards, promotional limits, and identity checks consistently (UKGC Opening Accounts Guide).
In this article, you’ll learn:
- What the one-account rule means in practice
- Why UK-licensed casinos enforce it
- How duplicate accounts are detected
- Consequences of breaching the rule
- What to do if an account is opened by mistake
This article explains why the one-account rule exists, how duplicate accounts are identified, and what happens if a player unintentionally or deliberately opens more than one account.

What the One-Account Rule Means
The one-account rule means that each individual is permitted to hold only one active account per casino operator. Creating multiple accounts using different email addresses, devices, or payment methods is typically prohibited under casino terms and conditions.
This requirement allows operators to:
- Apply age and identity verification correctly
- Monitor gambling behaviour consistently
- Enforce deposit, loss, and time limits
- Ensure promotional offers are applied fairly
The UK Gambling Commission explicitly states that account creation must be transparent and verifiable, with clear responsibility placed on the individual registering the account (UKGC Opening Accounts Guide).
Important Note: Duplicate accounts are one of several preventable rule breaches covered in our overview of how to avoid violating casino T&Cs.
Why Casinos Enforce a Single-Account Policy
Single-account policies exist primarily to protect consumers and ensure regulatory compliance. Multiple accounts can undermine safeguards designed to reduce gambling-related harm.
Key regulatory reasons include:
- Responsible gambling controls: Multiple accounts could bypass limits or self-exclusion tools.
- Promotional fairness: Welcome offers and free bets are generally limited to one per customer under promotional play restrictions (UKGC Promotional Play Restrictions).
- Fraud prevention: Duplicate accounts increase risks of identity misuse and financial crime.
UKGC consultation responses highlight the importance of consistent limit application and clearer accountability at the individual account level, which is not possible if multiple accounts exist (UKGC LCCP Consultation Response 2023).
How Duplicate Casino Accounts Are Detected
UK-licensed casinos use a combination of manual and automated checks to identify duplicate accounts. These checks are applied regardless of whether a player accesses services via desktop or mobile platforms.
Common detection methods include:
- Matching personal details such as name, date of birth, or address
- Verification of identity documents
- Analysis of device identifiers and IP data
- Cross-checking payment methods
These processes are part of standard compliance controls and are designed to operate proportionately and securely.
What Happens If You Break the One-Account Rule
If a casino identifies more than one account linked to the same individual, actions may include:
- Temporary suspension while the issue is reviewed
- Closure of duplicate accounts
- Removal of promotional benefits obtained through multiple accounts
- Withholding of funds if terms have been breached
Outcomes depend on the circumstances and whether the duplication was accidental or deliberate. UKGC guidance emphasises transparency and fairness in how operators apply their terms, particularly where consumer understanding may be limited (UKGC Opening Accounts Guide).
Players are encouraged to engage with gambling services responsibly and to seek information on safe play resources if unsure about account rules.
Frequently Asked Questions (FAQ)
How do online casinos know if I have multiple accounts?
Casinos compare personal details, identity verification data, payment methods, and technical indicators such as devices or IP addresses to detect duplicate accounts (UKGC Opening Accounts Guide).
Is it illegal to make multiple accounts for free trials?
While not a criminal offence in itself, creating multiple accounts to access promotions typically breaches casino terms and promotional play restrictions (UKGC Promotional Play Restrictions).
What happens if I try to create a second casino account?
The account may be flagged, suspended, or closed. Any promotional benefits may be removed, and further verification may be required.
Are there any special cases for opening multiple accounts?
Generally no. Each individual is limited to one account per operator. In rare cases, customer support may assist if an old account was closed or inaccessible, but this must be resolved directly with the operator.
In Summary
The one-account rule is a core requirement for UK-licensed casinos. It supports responsible gambling controls, promotional fairness, and regulatory oversight. Duplicate accounts undermine these safeguards and may result in account restrictions or closures.
