Organisation Data Service

We're responsible for publishing codes that identify organisations and individuals across health and social care.

The way you access our data will soon be changing. Application programming interfaces (APIs) are replacing the CSV files used for organisation data.

About the Organisation Data Service

The Organisation Data Service (ODS) is responsible for publishing organisation and practitioner codes, along with related national policies and standards. We're also responsible for the ongoing maintenance of the organisation and person nodes of the Spine Directory Service, the central data repository used within various NHS systems and services.

Why does my code look different?

The new ANANA code format has now formally come into use for all new code requests.

New code requests will be given an ANANA code with a structure of 5 alternating alphabetic and numeric characters, for example - G7H8J. This means it will no longer be possible to identify the type of organisation from the way it is structured.

Detailed guidance on this change is available on our information portal.

If you have concerns about accepting or consuming an ANANA code, please complete our ANANA code issue form.
