Global Coordination Groups: Official IASC Cluster Names and 3-Letter Codes

OCHA Digital Services maintains this reference dataset of IASC-designated Global Clusters and Areas of Responsibility (AoR) as of March 2026. It provides standardized naming conventions, 3-letter acronyms, and classification groups for humanitarian coordination entities to ensure interoperability across platforms.

Use Cases

• Standardizing 'Preferred Term' across humanitarian datasets to ensure cross-platform interoperability
• Mapping 'Acronym' codes to full names in operational presence dashboards and maps
• Categorizing entities by 'Group' to distinguish between Global Clusters and Areas of Responsibility in reporting

Strengths

• Standardized HXL hashtags for automated data processing
• Official OCHA-validated nomenclature
• Includes 3-letter cluster codes used in humanitarian reporting

Limitations

• Small record count limited to global-level entities
• Beta status indicates potential for schema or naming updates
