Problem

Parcel identification in the United States relies on a multitude of local numbering schemes that differ by county and jurisdiction, creating data silos and requiring costly normalization for each new application. This fragmentation hampers interoperability across government, insurance, real‑estate, finance, construction, and emerging AI‑driven geospatial platforms, leading to inaccurate analyses, delayed permitting, and inefficient emergency response.

Solution

Open Parcel Numbers (OPN) establishes a globally unique, persistent identifier for every land parcel in the United States. The OPN standard normalizes parcel data at the source, providing a single, reproducible reference that can be shared across jurisdictions and industries. By publishing parcel updates—splits, joins, transfers—through a lightweight, free interface, OPN ensures that identifiers remain current and trustworthy. The standard aligns with FGDC directives and OGC cadaster initiatives, enabling seamless integration with digital twins, blockchain registries, AI models, and other geospatial systems without the need for repeated data transformation.

Target Audience

Primary customers include government agencies, insurers, real‑estate and finance firms, construction and utility companies, as well as developers of AI‑driven geospatial analytics and digital twin platforms that require reliable, interoperable parcel data.
