Details

Overview

The Integrated Taxonomic Information System (ITIS) is a partnership of U.S., Canadian, and Mexican agencies, and other organizations, producing a curated reference of global taxonomic information. Each taxon is assigned a persistent Taxonomic Serial Number (TSN) that facilitates integration and reconciliation across biodiversity, ecological, and regulatory datasets.

Data Scope

  • Scientific and common names with synonymy and name usage
  • Hierarchical classification spanning kingdoms to species (and infraspecific ranks)
  • Authorship, publication, and nomenclatural references
  • Geographic data indicators and taxonomic status flags
  • Cross-references to other authoritative nomenclature sources where available

Access & Services

Programmatic access is provided via publicly available REST services returning JSON for record lookup, hierarchy traversal, and search queries. Bulk database downloads support offline integration and local analytics. OBO, OWL, and OBO Graph JSON exports are available via the OBO DB ingest transformation for ontology/graph workflows.

Licensing & Use

ITIS data are in the public domain. Users may copy and use the data freely with appropriate attribution recommended (e.g., citing ITIS and access date). See the access and data use policy page for details.
