New address-to-district mapping capability enables real-time civic engagement at scale through instant access to federal, state, and local legislative district data

FiscalNote Holdings, Inc. (OTC:NOTE), a global leader in AI-driven policy and regulatory intelligence, today announced the expansion of its PolicyNote API to include address-to-district matching powered by VoterVoice, FiscalNote's leading grassroots advocacy platform. The new endpoint enables developers and advocacy organizations to instantly resolve any U.S. address to its corresponding federal, state, and local legislative districts delivering a best-in-class capability built entirely in-house. Voter Voice matches millions of addresses a year and includes numerous enhancements and refinements from having delivered this service to customers for the past 25 years. Unlike competitors who rely on third-party vendors for district matching and inherit their limitations, FiscalNote owns and maintains its district data infrastructure, ensuring an unmatched level of accuracy that organizations can depend on when it matters most.

With the advocacy season for "fly-ins" to Washington DC and state capitals across the country now underway, organizations are increasingly building custom constituent engagement tools that require precise, real-time knowledge of who represents a given address. Until now, assembling that data required stitching together multiple sources or building proprietary matching infrastructure. The VoterVoice-powered district matching endpoint eliminates that complexity with a single API call.

Bringing the Power of VoterVoice to the PolicyNote API

VoterVoice has long been the backbone of grassroots advocacy for thousands of organizations across the country, powering more than 100 million constituent-to-legislator connections. By integrating VoterVoice's address-to-district matching capability into the PolicyNote API, FiscalNote makes this infrastructure available programmatically for the first time with no dependency on an existing VoterVoice account or active advocacy campaign required.

This integration marks a significant expansion of what the PolicyNote API can do. Organizations have always been able to use the API to track legislation and monitor the policy landscape, now they can act on it too. With district matching built in, developers can build workflows that not only surface relevant policy, but also connect constituents with their legislators. From tracking a bill in committee to mobilizing supporters in the right districts, the full advocacy workflow is now available programmatically in one place. Organizations can also pair the API's district matching capabilities with FiscalNote's Advocate Acquisition Program, which uses targeted digital campaigns to recruit new, verified supporters on a cost-per-acquisition basis — ensuring that when fly-in season arrives, they have the constituents in the right districts to make an impact.

"The VoterVoice API has been an invaluable component of our advocacy toolkit," said Brett Walter, CEO of Climate Action Now. "It has enabled us to build an application that powers real citizen advocacy, allowing people to make their voices heard on the policies and laws that matter to them. As a result, we've been able to build a custom experience that's had a direct impact on our ability to drive meaningful civic engagement."

The district matching endpoint is pure data consumption: submit an address, receive back a structured response containing the corresponding federal, state, and local legislative districts. It integrates seamlessly into existing workflows whether organizations are building fly-in coordination tools, civic engagement apps, contact management systems, or AI-powered advocacy platforms.

The capability is available immediately through the PolicyNote API. Organizations can access district matching data alongside the legislative, regulatory, and stakeholder intelligence already available through the PolicyNote API.

"As advocacy organizations gear up for fly-in season, having accurate, real-time district data is the difference between a constituent reaching their legislator and their message falling through the cracks," said Josh Resnik, CEO and President of FiscalNote. "Bringing VoterVoice's district matching into the PolicyNote API gives our customers a differentiated, developer-friendly capability that directly powers the kind of civic engagement that moves policy."
