A CIFAS marker does not appear on your credit file. It sits on the separate National Fraud Database, which is why many people only find out about one after a surprise rejection from a bank, lender or mobile provider. This guide shows you how to check both CIFAS and your three main credit files in one go, all for free.
What you are looking for. A marker on CIFAS can block new current accounts, savings accounts, mortgages, credit cards and even some mobile phone contracts. Your credit file, held by Experian, Equifax and TransUnion, may contain separate negative entries such as defaults, late payments or linked addresses that make the problem worse. You need to see all four reports to understand the full picture.
Step 1 — Request your CIFAS subject access request (DSAR). Under UK GDPR you have the right to see what CIFAS holds about you. Visit cifas.org.uk, go to the Individuals section, and complete the online Subject Access Request form. You can also write to CIFAS at their published address if you prefer paper.
Step 2 — Give CIFAS complete identity details. Include every name you have used, your full date of birth, and every address from the last six years. CIFAS matches markers on name, date of birth and address history, so missing an old address is the most common reason a DSAR comes back blank when a marker actually exists.
Step 3 — Upload proof of ID and address. Use a clear passport or driving licence scan, plus a recent bank statement, council tax bill or utility bill dated within the last three months. Keep a copy of your submission and the reference number CIFAS sends back.
Step 4 — Wait up to one calendar month. The 30-day response clock starts once CIFAS has enough information to identify you, not the day you first contact them. If they need more ID, reply quickly to avoid delays.
Step 5 — Read the CIFAS response carefully. If a marker exists, the letter will show the member organisation that filed it, the case type, the load date and how long it will remain. Common types are first-party fraud, misuse of facility, application fraud and victim-of-impersonation protective registration.
Step 6 — Check Experian. Use the free statutory credit report at experian.co.uk. By law you can request one free copy every 30 days. Look for defaults, missed payments, linked addresses and any searches you do not recognise.
Step 7 — Check Equifax. Request your free statutory report through equifax.co.uk or the ClearScore app. Compare it with Experian: not every lender reports to every bureau, so a problem may appear on one file and not the others.
Step 8 — Check TransUnion. Use the free statutory report at transunion.co.uk or the Credit Karma app. Again, look for entries that do not match your records, including old addresses, unknown accounts and hard searches you did not authorise.
Step 9 — Dispute anything that is wrong. Each bureau has an online dispute process. If an entry is inaccurate, request its correction or removal. If a lender refuses, you can escalate to the Financial Ombudsman Service or the Information Commissioner's Office.
Step 10 — Request the bank's evidence. CIFAS only hosts the marker; the bank or lender that filed it owns the decision. Send that organisation a separate DSAR asking for the fraud investigation file, call recordings, internal notes and the evidence used to meet the CIFAS filing standard.
What if CIFAS says no marker exists? A nil response means no marker was matched to the details you supplied. If banks are still refusing you, focus on the three credit files instead. If a marker does exist, the filing standard is strict: the bank must hold evidence that would support a report to the police. Many markers, especially misuse-of-facility cases wrongly labelled as first-party fraud, do not meet that standard.
What not to do while you investigate. Avoid making repeated applications for accounts. Each refusal can be used against you later, and every hard search damages your credit file. Gather the facts first, then act.
