Codelists

The IATI codelists are key to making IATI activity and organisation data from different publishers comparable.

Codes are used to represent many standard values in an IATI activity. For example, codelists such as organisation type ensure that different publishers have unambiguous, comparable definitions (e.g. 23 = Regional NGO; 60 = Foundation; or 70 = Private Sector) they can use when describing activities.

Codelists are updated through a managed process. A codelist can either be embedded (centrally managed by IATI) or non-embedded (derived from an authority source).

For every codelist, the embedded status, alongside the relevant IATI element(s) are declared and linked to.

An API is also available for accessing codelists.
