Truthset’s latest analysis reaffirms Experian as the leader in third-party data accuracy. Advertisers and partners can rely on Experian’s validated, AI-powered solutions to reduce waste, improve personalization, and drive measurable marketing outcomes grounded in accuracy.Experian continues to lead in data accuracy according to Truthset’s latest analysis
Advertisers, technology partners, and agencies are all chasing accurate data to power their marketing strategies. But not all data is created equal. Truthset’s latest findings confirm Experian’s leadership in third-party data accuracy, giving brands and agencies confidence in every decision they make.
Accurate data is the foundation for predictive insight, real-time intelligence, and AI-powered personalization. Experian’s AI-driven solutions help marketers move from data to action, delivering more relevant messages with less waste.
Truthset’s independent study found that up to 51% of ad targeting data is inaccurate, with accuracy rates ranging between 32% and 69% across providers. This reinforces the importance of validated, trusted data from partners like Experian.
The data quality challenge
Inaccurate data can lead to:
Wasted ad spend
Without accurate data at the start, marketers can’t reach the right audiences, resulting in wasted impressions.
Privacy and compliance risks
In an increasingly privacy-centric world, advertisers need to be especially mindful of accurate targeting to avoid putting their brand reputation at risk.
Poor campaign performance
Low-quality data skews metrics and attribution models, making it difficult to measure campaign success and optimize spend.
Low-quality data can come in different forms, like inconsistent or outdated information – think demographics (age, gender) and interests (dog versus cat lover), or simply the wrong relationship can be made between data sets. Data records can be incomplete or duplicative, and data segments could be misclassified or inaccurate. For example, a kids’ snack food company may think they’re targeting a 35-year-old man, who lives in the suburbs with his young family, when in fact it’s a 65-year-old woman who moved to the city after her kids went to college. That’s wasted investment.
As data ecosystems grow more complex, that’s where Experian’s AI-powered simplicity comes in. We can clean, enrich, and infer missing signals, helping you act on incomplete or imperfect data with greater confidence.
Building a solid data foundation
Accurate data is essential for personalization and trust. According to eMarketer, more than 75% of internet users worldwide are willing to share their email address, brand interest, and name in exchange for personalized experiences. Without accurate data, marketers won’t be able to provide the level of personalization that consumers desire.
But personalization at scale requires more than just data, it needs intelligence. Experian’s AI-powered capabilities, including predictive models, transform clean, validated data into meaningful engagement strategies that balance performance with privacy. Independent validation from Truthset ensures that Experian’s data remains among the most accurate in the ecosystem.
“As cookies and mobile ad identifiers continue to phase out, consented, durable identifiers (hashed email, postal addresses) are going to serve as the foundation for identity solutions of the future. And the only way to ensure you are transacting on the highest quality identity and demography data is to actively validate the data you rely on with a third party.”
Chip Russo, President at Truthset
Experian’s commitment to data accuracy
Since joining the Truthset Data Collective in 2023, Experian continues to be the industry leader in data accuracy. Truthset’s latest Q2 2025 analysis reaffirms our leadership in data accuracy:
- Experian is the #1 data provider of largest volume of high-accuracy hashed emails (HEMs)
- Experian ranks #1 in accuracy for eight marketing data attributes, including but not limited to Age, Geography, Presence of Children, and Education
- Experian ranks #1 or #2 for 22 of the 24 attributes, and #3 for the two others (out of 12 companies being analyzed)
- Experian consistently has the largest number of HEMs that are 90% or more likely to be accurate
“As a member of the Truthset Data Collective, Experian received top ranks across a variety of categories for its data. The entire digital advertising world runs on data, but focusing on data accuracy is going to drive the next phase of innovation for the industry, enhancing ROI for advertisers, CPMs for publishers, and relevant experiences for consumers.”
Chip Russo, President at Truthset
As Truthset’s recent study highlights, the data matched between hashed emails and postal addresses is crucial, underpinning everything from targeted ads to TV audience measurement. Highly accurate HEMs linked to high-quality demographic data should be the foundation of any marketing plan. Advertisers are able to overcome the complexities of identity resolution by tying online and offline touchpoints together to deliver a consistent message across channels.

Cookies are leaving us, but that doesn’t have to mean performance has to. That’s why Experian is taking the steps needed to future-proof identity in our Graph, including adding Unified ID 2.0 (UID2) from The Trade Desk. Experian currently supports UID2 in our Graph outputs for demand-side platforms (DSPs). UID2 support in our Graph outputs will be available to all approved partners by December 2023. In this blog post, we talk about why cookieless IDs, like UID2, that are coming to market because of cookie deprecation, are important, and how incorporating cookieless IDs into an identity graph can help you prepare for a cookieless future. What are cookieless IDs? Like cookies, cookieless IDs provide you with a comprehensive view of a consumer’s digital activity. Unlike cookies, identity providers produce cookieless IDs, using user-consented data and deterministic and probabilistic data signals (like hashed emails or mobile ad IDs). Cookieless IDs are a newer identifier that allows the advertising industry to maintain our understanding of consumers’ digital actions, helping to ensure we continue to generate smart, data-driven insights, targets, activation strategies, personalized experiences, and measurement and attribution. Why should you incorporate cookieless IDs into an identity graph? Adding cookieless IDs to an identity graph allows for licensees of the graph to: Resolve the universal ID to a consolidated consumer profile and know which other digital IDs tie to the cookieless ID Establish a unified view of the consumer with a privacy-compliant ID Produce data-driven and informed advertising strategies that still drive results, without the use of cookies Experian’s Graph Experian’s Graph is one of the most robust and signal agnostic identity graphs in the market. Experian’s Graph supports most digital IDs, including cookieless IDs, such as ID5, UID2, and Hadron ID. When you license Experian’s Graph, you increase your ability to better understand the different digital IDs that tie to a household or individual. Additionally, with our cookieless ID support, you can continue to understand your consumer and their digital IDs in the cookieless world. Why is it crucial to include UID2 support in Experian's Graph outputs? The Trade Desk is the largest, independent demand-side platform. They’ve created a cookieless ID, UID2, that they hope can power the advertising world to come across the open web. UID2 is an alternative solution to third-party cookies that when utilized in an identity graph, can offer a clearer picture of your consumer, enabling frequency controls and better management, across both digital and connected TV (CTV). Approved DSPs can add UID2s to their Experian Graph, giving them access to one of the more trusted and prominent cookieless IDs in the market today. Additionally, DSPs can use this identifier to decide whether to bid on certain inventory or not, on behalf of their advertiser partner. And, if we hedge our bets, it will only grow in prominence and use. While only available to approved DSPs today for use in the Experian Graph, the forthcoming encrypted UID2 token will provide this capability to the entire ecosystem, which allows us all to speak the same language and operate as efficiently as possible. "We are excited to support UID2, one of the premier IDs to support the future of addressability across the open internet, in the Experian Graph. We continue to see the adoption of UID2 across the demand-side ecosystem, increasing addressability across growing channels like CTV and beyond. I am personally excited to see how this momentum continues to increase over the remainder of 2023 and into 2024."chris feo, svp, sales & partnerships, experian Future-proof your identity strategy with Experian Graph and UID2 We’ve seen the impact that cookies have had on digital advertising and marketing. With the impending third-party cookie deprecation, you will need to adopt alternative cookieless ID solutions such as Unified ID 2.0. Experian is well-positioned to help you navigate this change, offering UID2 support in our Graph outputs for all approved partners by December 2023. Take the right steps now to future-proof your identity strategy and discover lasting success even without cookies.

As we move from 2023 to 2024, we’ll likely see collaboration extending outside businesses, meaning data can be shared with external partnerships in the form of a data ecosystem.

We are excited to announce that we’ve updated our CAPE data with 2020 Census data. This release updates estimates and projections from 2010 and replaces all previous CAPE data attributes. U.S. Census data offers a great opportunity for data enrichment The U.S. Census is conducted every 10 years to determine the number of people living in the U.S. in addition to collecting data on dozens of topics across 130+ surveys and programs. U.S. Census data is already broken out into regional groups and covers 100k+ different geographies: States, counties, places, tribal areas, zip codes, and congressional districts. Block groups are the smallest geographic area for which the Bureau of the Census collects and tabulates data. They are formed by streets, roads, railroads, streams, other bodies of water, and other visible physical and cultural features. What is CAPE? Census Area Projections & Estimates data (CAPE) data from Experian utilizes a proprietary methodology to make the data easy to action on for marketing use cases. Made from U.S Census and Experian consumer data, CAPE data sets are developed at the block group and zip code level and targetable at the household level. CAPE 2020 updates CAPE 2020 uses the 2020 Census data blended with other Experian data to update CAPE’s unique attributes for data enrichment and licensing. Multiple sources are used and data is delivered at a block group level or zip code. Experian provides unique CAPE attributes not available through other sources that provide Census data. These include our Ratio and Percentages attributes, Score Factors/Segments, and Mosaic. CAPE 2020 use cases Our CAPE 2020 data sets enable strategic marketing analysis and decision-making. You can use CAPE 2020 data to understand the differences in the markets you serve as they relate to core demographics, housing attributes, education, income, employment, spending, and more.
