What Is A Nationwide Building Society CIFAS Marker?
A Nationwide Building Society 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 Nationwide Building Society, and the evidence relied on when the marker was filed.
Research identifies Nationwide Building Society as the relevant legal entity for Nationwide Building Society, trading as Nationwide, FCA reference 106078. Nationwide public information gives FCA/PRA registration number 106078 and complaints route; FCA final notice is saved as public source context. Relevant published Ombudsman or regulator material includes: https://www.fca.org.uk/publication/final-notices/nationwide-building-society-2025.pdf.
In a Nationwide Building Society 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. Nationwide Building Society must be able to justify the marker with evidence, not suspicion, assumption, or a general account concern.
