At Least 48% of States Now Use Data Matching Technology to Proactively Find Owners of Unclaimed Property Worth Over $100

Data matching technology has become a critical tool for state treasuries seeking to return unclaimed property to its rightful owners.

Data matching technology has become a critical tool for state treasuries seeking to return unclaimed property to its rightful owners. Rather than waiting for individuals to search for their abandoned funds, states are increasingly using sophisticated data verification systems to proactively match unclaimed property holdings with tax records, business databases, and other government records. This automated approach has proven remarkably effective: Delaware’s MONEY MATCH program alone returned nearly $400,000 to approximately 2,800 taxpayers in 2025 by cross-referencing tax returns with unclaimed property records, demonstrating how passive notification can transform recovery rates.

The shift toward data matching represents a fundamental change in how states approach unclaimed property administration. Instead of relying on citizens to actively search for their own funds—a process that historically resulted in the majority of unclaimed property going unclaimed indefinitely—state treasuries now employ technology to identify likely owners and contact them directly. This proactive methodology has gained momentum across multiple states, with programs like Illinois’s enhanced Money Match system returning $13.2 million to 138,000 residents and Vermont’s MoneyBack program distributing $9.9 million to over 31,000 people in fiscal year 2025.

What Is Data Matching Technology in Unclaimed Property Recovery?

Data matching in the unclaimed property context refers to the process of cross-referencing a state’s holding database with other government records—primarily tax returns, driver’s license applications, and business registration documents—to identify the most likely current owners or their heirs. When a match is found with sufficient confidence, the state’s treasury office contacts the individual directly rather than expecting them to search for funds they likely don’t know they have. This technology eliminates the traditional friction point that prevented unclaimed property owners from recovering their money: the knowledge gap. The system works through sophisticated algorithms that account for name variations, address changes over time, and the fact that many unclaimed property claims date back decades.

When a taxpayer files a return, for example, the state’s unclaimed property management system can automatically scan its holdings for matching names and amounts. If a match meets the threshold for automated contact, the state sends a notification. Pennsylvania, Delaware, Illinois, and Vermont have all implemented variations of this matching approach, each reporting significant success rates in contacting and returning funds to owners. The limitation of automated matching, however, is that it works best for accounts with clear ownership trails; more complex claims involving estates, business accounts, or disputed ownership still require manual review and investigation.

How Automated Data Verification Transforms Recovery Rates

The impact of data matching on recovery rates has been substantial enough to reshape how state treasuries prioritize their resources. Illinois’s enhanced Money Match program demonstrates this impact clearly: by automating the process of identifying likely owners within their tax database, the state moved $13.2 million out of the unclaimed property vault and back to residents without requiring those residents to file a claim or even know the money existed. Vermont’s MoneyBack program achieved similar results with $9.9 million returned to 31,000+ individuals in a single fiscal year, suggesting that the volume of matchable funds is far larger than previously understood.

The efficiency gains are twofold: states spend less per claim on investigation and verification when they can automate the matching process, and citizens receive their money faster. However, a critical limitation exists in the scope of what data matching can accomplish. The technology excels at matching individuals with personal accounts—dormant savings accounts, unclaimed wages, insurance proceeds, utility deposits—but struggles with business accounts, estate claims, and accounts where the deceased owner’s heirs are not yet identified. Additionally, privacy concerns and data security requirements mean that not all state databases can be directly interconnected; many states still rely on periodic data sharing agreements rather than real-time matching systems.

State Success Stories and Current Adoption Patterns

Delaware’s MONEY MATCH program represents one of the most transparent examples of data matching in action. Launched to specifically target unclaimed property held in the state treasury, the program used tax return data to identify residents with matching names, addresses, and account details. The 2025 results—$400,000 returned to 2,800 taxpayers—came from what Delaware describes as passive matching that required no additional action from the property owners themselves. These taxpayers received notification and either accepted the return or made a simple claim; the state handled the verification automatically using existing government records.

Pennsylvania’s Money Match program operates on a similar principle, though the state has been more selective about public reporting of specific results. Vermont’s MoneyBack initiative goes further by combining tax data matching with proactive outreach through direct mail and digital notification, resulting in the recovery and return of funds across multiple fiscal years. The common thread across all these programs is that they treat data matching not as an occasional special project but as an integrated part of their unclaimed property administration infrastructure. The industry standard for unclaimed property management—approximately 43 government programs currently use Kelmar Associates’ KAPS® management system—increasingly incorporates data matching capabilities as a standard feature rather than an optional enhancement.

The National Infrastructure Supporting Automated Matching

Beyond individual state programs, a broader infrastructure supports unclaimed property recovery at the national level. The MissingMoney.com database, sponsored and maintained by the National Association of Unclaimed Property Administrators (NAUPA), aggregates unclaimed property records from all 50 states plus the District of Columbia. While MissingMoney itself is a searchable database that relies on individual initiative, the underlying multistate framework enables states to share data and verify ownership claims across state lines.

This is particularly important because individuals move frequently, and unclaimed property accounts may be held in states where the owner no longer resides. The comparison between individual state data matching and the national MissingMoney infrastructure illustrates an important point: state-level automation delivers faster results for in-state claims, but the national database serves as a backup mechanism for people who move between states or whose unclaimed property was created in a state where they no longer live. For someone who had a dormant account in Delaware but now lives in Colorado, the state-to-state data sharing capabilities and the multistate database become essential. However, the tradeoff is that national databases move slower than automated state systems, and not all states have integrated their data matching systems with the multistate framework in real time.

Limitations and Challenges in Data Matching Implementation

Despite the clear benefits of data matching technology, several practical limitations constrain how broadly these systems can be deployed. The most significant limitation is that matching algorithms work best when the name and address information in the unclaimed property account closely matches current government records. For accounts with outdated or misspelled names, or for individuals who have changed their name through marriage, adoption, or legal process, automated matching fails and the account falls back to the slower manual claim process. Additionally, surviving family members of deceased account holders present a particular challenge—the data matching system cannot easily identify heirs without explicit estate information or a claim filed by the heir themselves. A second critical limitation involves data access and privacy regulations.

Not all state government databases can be legally connected for the purpose of unclaimed property matching. Some states’ tax records, for example, are protected by confidentiality statutes that prevent treasury offices from cross-referencing them with unclaimed property holdings. This means that states with the strictest privacy protections may be unable to deploy the most advanced matching systems, even if they wanted to. The warning here is important: if you have moved frequently, changed your name, or have unclaimed property in a state with strict data access rules, relying solely on automated matching systems to contact you is risky. Periodic manual searches of state treasury websites and the MissingMoney database remain essential for comprehensive coverage.

Real-World Impact: Who Benefits Most from Data Matching Programs

The individuals who benefit most from data matching programs are those who have unclaimed property from personal financial accounts—dormant bank accounts, unclaimed wages from former employers, insurance proceeds, and utility deposits. These accounts typically have clear ownership information and match readily with tax records or driver’s license databases. For example, if you had a savings account at a regional bank that closed, and you didn’t access the account for five years, the bank would transfer the funds to the state’s unclaimed property vault.

If that state uses data matching, and your current tax return matches the name and address on the old savings account, you would receive a notification directly—no searching required. In contrast, complex claims involving estates, business accounts, or situations where ownership is disputed do not benefit from automated data matching. If you are an heir to an uncle’s unclaimed property account from 30 years ago, no matching system will identify you without a specific claim filed by you or an executor. Similarly, if your business had unclaimed property related to employee accounts or insurance proceeds, the matching system may flag the business entity but will not automatically distribute funds without proper authorization and documentation from current business principals.

The Future of Unclaimed Property Technology and Proactive Recovery

The trend toward data matching in unclaimed property administration is likely to continue expanding as states invest in technology infrastructure and privacy regulations evolve. Industry analysts and state treasury associations have increasingly emphasized that proactive recovery—finding owners rather than waiting for owners to search—is the most equitable approach to unclaimed property administration. As more states adopt automated matching systems, the percentage of unclaimed property that remains unclaimed will likely decline, though the total amount of unclaimed property in state vaults will continue to grow due to ongoing account dormancy and account transfers from failed financial institutions.

One forward-looking development is the integration of data matching systems with real-time notification capabilities. Rather than batch processes that match data quarterly or annually, some states are moving toward continuous matching where funds are identified and owners are contacted as soon as a match is confirmed. This reduces the time between account dormancy and owner recovery, and it also reduces the liability and administrative cost for states holding the funds.

Conclusion

Data matching technology has fundamentally improved the unclaimed property recovery process in states that have adopted it, with documented success in Delaware, Illinois, Vermont, Pennsylvania, and other jurisdictions. The technology works best for personal financial accounts with clear ownership records, and it delivers results far faster than traditional methods relying on individual searches. However, no matching system is comprehensive—complex claims, estates, business accounts, and situations involving outdated information still require manual intervention and individual claims filing.

If you have unclaimed property, the most comprehensive approach combines both automated and manual strategies. Start by searching the MissingMoney.com database directly, then check your specific state treasurer’s website to see whether your state offers a data matching program. If your state has an automated program, ensure your tax records and government identification are current so you are more likely to be matched. For complex situations or accounts that may be unclaimed in multiple states, periodic manual searches remain essential, as no automated system yet covers all possible ownership scenarios across all states simultaneously.
