Cracking the Code: How Credit Data and Alternative Data Sources Transform Your Marketing Decisions

As a consumer lender, making effective lending decisions is crucial to your business’s success. With the ever-increasing amount of competition in the lending industry, you need to be able to identify those who can pay back their loans. And weed out those who cannot. Lenders have relied on traditional credit bureaus to assess creditworthiness for decades, but this is no longer sufficient. Here’s when alternative credit data sources become crucial. 

Today, roughly 32 million American adults are considered unscoreable by traditional credit models alone – a population that represents a real lending opportunity for institutions willing to look beyond the bureau.

In this blog, we will explore how credit data and alternative sources can be leveraged for effective consumer lending decisions. Altair Data combines tri-bureau credit data with alternative sources and 1,000+ consumer marketing attributes to give lenders a complete picture of who qualifies and who’s actually ready to act. 

The Role of Credit Data for Lenders

Credit data is an important factor in assessing creditworthiness. The credit bureau collects credit information and creates a credit report for each consumer. This report provides a detailed history of credit accounts, credit limits, payment histories, and any delinquencies or defaults. However, traditional credit bureaus do not consider the full picture of a consumer’s financial situation. 

What are Alternative Credit Data Sources?

Alternative credit data refers to non-traditional information used to evaluate creditworthiness – including rent payments, utility bills, telecom accounts, employment history, and cash flow data. It’s especially useful for consumers with limited or no conventional credit history. For lenders, it reduces risk blind spots and helps supplement credit information to identify good lending candidates. 

Utility payment history is an alternative credit data source that can be leveraged well. By analyzing a consumer’s utility payment history, companies can assess creditworthiness. Those who consistently pay their bills on time demonstrate responsibility and reliability. Rental data is worth paying attention to for the same reason. Paying rent on time, month after month, is a real indicator of financial reliability. The caveat is that being on top of bills doesn’t tell you whether someone has breathing room in their budget. That’s exactly why no single data point should carry the whole decision. 

How Online Financial Behavior Helps 

In conjunction with credit and alternative data, online financial behavior can be another valuable source of data. Companies can analyze a person’s online financial activity to determine their spending habits, regular income, and living expenses. Social media and online shopping habits can reveal a lot about someone’s financial reality. A person who consistently splurges on high-end purchases while carrying existing debt may not be in the best position to take on a new loan – and that context matters when making a sound lending decision. 

Lenders who rely on one data source are working with gaps. 

Credit bureaus tell you about tradelines and payment history but not about rent or utilities. Alternative data fills those gaps but doesn’t tell you about open credit. Behavioral data adds context but can’t stand alone. Using all three together gives lenders a sharper read on a borrower’s actual financial position – and sharper reads translate directly into smarter lending decisions. 

What Are the Benefits of Multiple Data Sources?

1. Enhanced Decision-Making

Multiple data sources provide a wider range of information, leading to more informed decision-making. This can help in crafting more effective acquisition campaigns.

2. Improved Customer Segmentation

By leveraging data from various sources, you can gain deeper insights into customer behavior and preferences, enabling better segmentation and targeting of your marketing efforts.

3. Risk Management

Utilizing multiple data sources reduces the risk of relying heavily on one data stream, which may not always be accurate or comprehensive.

4. Personalized Marketing

With a broader understanding of customer behavior, you can personalize your marketing messages to resonate more with your target audience. Altair Data helps marketers activate trigger campaigns based on solid intent data.

5. Competitive Advantage

Employing a multitude of data sources can give you an edge over competitors who may only be using traditional data points. The more knowledge you have, the better you can strategize and outperform the competition.

6. Increased ROI

Ultimately, the use of multiple data sources can lead to better returns on your marketing investment, as your campaigns are more likely to reach and resonate with the right audience. With Altair Data’s comprehensive solutions, clients can unlock up to 50% more qualified prospects compared to single-bureau data.

Transform Your Strategy Today

Roughly 32 million American adults are unscoreable by traditional credit models alone – a population that’s largely invisible to lenders relying on bureau data in isolation. 

Combining tri-bureau credit data with alternative sources like rent, utility, telecom, employment, and cash flow data brings those consumers into view, sharpens credit decisions, and reduces the blind spots that come with single-source models. For lenders competing for qualified borrowers in a crowded market, that broader view directly affects how many loans get funded and how those loans perform.
