What Is A 3 CIFAS Marker?
A 3 CIFAS marker is a fraud-risk record connected to application, account, product, transaction, affordability, or fraud investigation records. It is not a normal credit issue. It is a fraud-risk filing on the National Fraud Database and should be reviewed against the CIFAS category used, the records held by 3, and the evidence relied on when the marker was filed.
Research identifies Hutchison 3G UK Limited as the relevant legal entity for 3, trading as 3 / Three UK, company number 03885486, ICO registration Z5513412. Three privacy notice says Three UK and Vodafone Limited merged in June 2025 and are now part of VodafoneThree.
In a 3 case, the marker may relate to:
- The application or onboarding process
- Affordability, income, or supporting information
- Transaction, account, or product records
- Identity or fraud prevention checks
- How the product, account, or facility was obtained or used
The key point is simple. 3 must be able to justify the marker with evidence, not suspicion, assumption, or a general account concern.
