Data Methodology

Transparency in how we collect, verify, and maintain the most comprehensive EPA compliance provider database in the United States.

Our Commitment to Data Accuracy

FacilityComplianceUS maintains a database of over 987,000 compliance service providers across all 50 U.S. states and territories. Unlike directories that rely on user submissions, our data originates from official government sources and undergoes continuous verification.

Primary Source

All listings originate from official EPA, DOT, and state licensing databases—never user submissions.

Continuous Sync

Automated weekly synchronization with federal databases ensures data reflects current registration status.

Anomaly Detection

Machine learning identifies data inconsistencies for manual review before publication.
