farmid

Farmid is a term used to denote a unique identifier assigned to a farm within agricultural information systems. It serves as a stable reference that links farm-specific data across different applications, such as production records, agronomic plans, input purchases, inspections, subsidies, and traceability workflows. In practice, farmids enable data from disparate sources to be combined at the farm level, rather than by individual fields or unrelated entities.

Typically, a farmid is issued by a registry or by a software platform that manages farm data. Formats vary widely and may be numeric, alphanumeric, or include regional prefixes. The length and structure depend on the issuing system and may be designed to support hierarchical relationships, linking a farm to its parcels, operations, or business units.

Governance of farmids ranges from official registries maintained by government or regional authorities to private sector databases used by agribusiness platforms. Proper governance addresses uniqueness, deduplication, data quality, and privacy controls, and often includes procedures for updating records when ownership or operation changes.

Common uses include enabling data interoperability across farm management systems, supporting supply chain traceability, determining eligibility for subsidies or insurance, and facilitating performance analytics. While farmids improve data integration, challenges include potential duplication across registries, inconsistent data standards, and privacy concerns when sharing farm-level information.
