Solving the Fraud Problem: What is First-Party Fraud?

Updated: July 14, 2026 by Chris Ryan 5 min read October 31, 2023

In a series of articles, we talk about different types of fraud and how to best solve for them. This article will explore first-party fraud and how it’s similar to biting into a cookie you think is chocolate chip, only to find that it’s filled with raisins. The raisins in the cookie were hiding in plain sight, indistinguishable from chocolate chips without a closer look, much like first-party fraudsters.

What is first-party fraud?

First-party fraud refers to instances when an individual purposely misrepresents their identity in exchange for goods or services. Borrowers may falsify income, misrepresent employment or exploit credit systems without the intention of repaying. In the financial services industry, it’s often miscategorized as credit loss and written off as bad debt, which masks true fraud exposure and distorts credit-risk forecasting.

Common types of first-party fraud include:

  • Chargeback fraud: Also known as “friendly fraud,” chargeback fraud occurs when an individual knowingly makes a purchase with their credit card and then requests a chargeback from the issuer, claiming they didn’t authorize the purchase.
  • Application fraud: This takes place when an individual uses stolen or manipulated information to apply for a loan, credit card or job. In 2023, the employment sector accounted for 45% of all false document submissions — 70% of those who falsified their resumes still got hired.
  • Fronting: Done to get cheaper rates, this form of insurance fraud happens when a young or inexperienced individual is deliberately listed as a named driver, when they’re actually the main driver of the vehicle.
  • Goods lost in transit fraud (GLIT): This occurs when an individual claims the goods they purchased online did not arrive. To put it simply, the individual is getting a refund for something they actually already received.
  • Bust-out: This occurs when an individual builds what appears to be good credit behavior over time, making small purchases and on-time payments, and then suddenly maxes out their credit lines or abandons repayment entirely. The account looks legitimate until the “bust-out,” making it one of the hardest forms of first-party fraud to detect.
  • Credit washing: This happens when an individual falsely disputes legitimate accounts or debts to have them removed from their credit report. By portraying valid obligations as fraud, the individual can temporarily improve their credit standing or access new credit they wouldn’t qualify for otherwise.

A first-party fraudster can also recruit “money mules” — individuals who are persuaded to use their own information to obtain credit or merchandise on behalf of a larger fraud ring. This type of fraud has become especially prevalent as more consumers are active online.

Money mules constitute up to 0.3% of accounts at U.S. financial institutions, or an estimated $3 billion in fraudulent transfers.

How does it impact my organization?

Firstly, first-party fraud can cause significant losses. According to our latest study, first-party fraud costs $36.7 million annually on average. Nearly one-third of respondents in our annual Identity and Fraud survey reported that first-party fraud had increased stress on their businesses.

An imperfect first-party fraud solution can also strain relationships with good customers and hinder growth. When lenders have to interpret actions and behavior to assess customers, there’s a lot of room for error and losses. Those same losses hinder growth when misclassification inflates credit-risk estimates and masks true fraud exposure.

This type of fraud isn’t a single-time event, and it doesn’t occur at just one point in the customer lifecycle. It occurs when good customers develop fraudulent intent, when new applicants who have positive history with other lenders have recently changed circumstances or when seemingly good applicants have manipulated their identities to mask previous defaults.

Finally, misclassified first-party fraud losses can impact how your organization categorizes and manages risk – and that’s something that touches every department.

Solving the first-party fraud problem

First-party fraud detection requires a shift in how we think about the fraud problem. It starts with the ability to separate first-party fraud and credit risk, since they are often indiscernible at origination. 

To effectively combat first-party fraud, businesses should consider the following actions:

  • Define first-party fraud as its own risk: Don’t blend it into credit loss. Build targeted models that use behavioral, identity and activity signals. Start with first-payment default as a key indicator.
  • Use a longer risk window: A 12-month view helps surface early fraud patterns and supports stronger credit and fraud analysis.
  • Unify fraud, credit and compliance decisions: Coordinated strategies reduce blind spots and improve customer experience.
  • Upgrade your models: Apply machine learning and segment by factors like credit age or product type to better detect bust-outs and early defaults.
  • Combine credit and noncredit data: Use device intelligence, identity velocity and behavioral data to help separate fraud from financial hardship.
  • Benchmark against peers: Regular comparisons help assess exposure, validate performance and refine strategies.

Ask the Expert: Unlocking the ROI of alternative data with Natasha Madan and Julius Heim

A visibility gap lenders can't afford to ignore Alternative data is often associated with thin-file or credit invisible consumers. But its value extends far beyond those segments. Experian's Clarity Services database includes approximately one in five credit-active consumers, including one in four consumers with prime-and-above credit profiles. That means lenders may be missing important signals, not only for emerging borrowers, but also for applicants who appear well qualified using traditional bureau data alone. Consider two consumers with the same credit score. Based on traditional credit data, they may appear equally creditworthy. But when Clarity data is added, one consumer may demonstrate stable repayment behavior while another shows recent defaults on alternative finance products. The credit score hasn't changed, but the decisioning context has. That's where alternative data creates value: helping lenders distinguish between consumers who look similar on paper but represent very different levels of risk and opportunity. In this Ask the Expert session, Experian’s Julius Heim, Vice President of Analytics Product Build, Innovation and Scores, and Natasha Madan, Senior Director, Analytics Consulting, explain how different alternative data assets solve different business challenges and why the greatest return comes from using them together throughout the credit lifecycle. What that visibility gap is really costing lenders Better visibility matters because every lending decision carries consequences. Without alternative data, lenders may approve applicants whose repayment behavior suggests elevated risk but isn't reflected in a traditional credit file. Without cash flow insights, they may decline consumers who appear thin file on bureau data despite demonstrating strong income and responsible financial management. The result is a two-sided cost: avoidable bad debt on one side and missed growth opportunities on the other. But ROI extends beyond approvals alone. It also appears through stronger marketing strategies, improved conversion, reduced friction and more precise risk segmentation throughout the lending lifecycle. "ROI can mean many things ... marketing to the right people, achieving better approval rates, reducing risk, getting less friction and overall profitability."Julius Heim, Vice President of Analytics Product Build, Innovation and Scores Where alternative data creates ROI Improve approval strategies Use additional consumer signals to recover creditworthy applicants while avoiding unnecessary declines. Reduce portfolio risk Identify elevated repayment risk earlier through enhanced visibility beyond traditional bureau data. Improve portfolio performance Increase conversion, reduce friction and strengthen profitability across the credit lifecycle. Different data. Different jobs. Not all alternative data solves the same problem. Clarity Services can help lenders strengthen decisions early in the customer journey. It provides additional visibility during prospecting and acquisition, helping identify potential risk before an application moves through the underwriting process. Cash flow insights can provide value in a different way. When traditional credit information offers part of the picture, consumer-permissioned cash flow data can provide greater insight into income, spending patterns and financial capacity. That makes it especially valuable as a second look during underwriting. Together, these complementary data assets help lenders improve decisioning throughout the credit lifecycle. They can support acquisition, underwriting, account management and collections while building on the trusted foundation of traditional bureau data. Research also continues to demonstrate measurable lift when cash flow insights are combined with traditional credit information. "I recently did a study with a client where we actually saw a 20% lift in KS [Kolmogorov-Smirnov] above and beyond credit bureau data. Again, the bureau data itself was very predictive. But even from the cash flow data, we still got a 20% lift, which is an amazing stat." Julius Heim, Vice President of Analytics Product Build, Innovation and Scores The greatest value comes from using these data sources together for a more holistic consumer view. Start with proof, then build Adopting alternative data doesn't have to begin with a large transformation. A practical first step is a data study. By comparing current decision strategies with enhanced data, lenders can identify where additional visibility creates measurable lift within their own portfolios. This approach allows institutions to validate results before making broader operational changes. Every lender has different workflows, technology environments and business priorities. A flexible implementation strategy helps organizations incorporate new data in ways that support existing processes rather than disrupting them. Three ways to get started Run a data study Benchmark current decision strategies and quantify potential lift. Start simple Begin with targeted data attributes or proven scores before expanding to more advanced use cases. Build with confidence Scale implementation based on measured business outcomes and organizational priorities. This approach allows lenders to validate results, build confidence and expand their strategy over time. Explore alternative data with a trusted partner Every lending decision benefits from better consumer insight. Experian helps lenders combine trusted credit data with alternative data, cash flow insights and advanced analytics to strengthen decisioning, improve portfolio performance and uncover new opportunities for growth. Whether you're evaluating alternative data for the first time or expanding an existing strategy, Experian can help you identify where additional consumer insight can create measurable business value.
