Welcome to DataCite

DataCite is a leading global non-profit organisation that provides persistent identifiers (DOIs specifically) for research data and other research outputs. Organizations within the research community join DataCite as members to be able to assign DOIs to all their research outputs. This way, their outputs become discoverable and associated metadata is made available to the community. DataCite then develops additional services to improve the DOI management experience, making it easier for our members to connect and share their DOIs with the broader research ecosystem and to assess the use of their DOIs within that ecosystem.

DataCite is an active participant in the research community and promotes data sharing and citation through community-building efforts and outreach activities.

Your organization must be a member of DataCite to register DOIs with us. If your organization is interested in joining DataCite please reach out to us by sending an email to [email protected] and expressing you interest. You can find more information about membership in our website.

You can also take a look at the DataCite Brochure for comprehensive information about the organization and services.

Some background on DOIs

DOI is an acronym for “digital object identifier." DOIs are a type of Persistent Identifier (PID) that uniquely identify digital research content. They are intended to be a permanent way of identifying and accessing a particular resource. DOIs form a persistent link that points to the repository or other digital location by including the URL in the metadata. This provides a system for persistent and actionable identification and interoperable exchange. DOIs remain fixed, but the location and other metadata may change. DataCite DOIs come with a metadata schema that includes a controlled vocabulary of 15 different resource types to describe the content being shared. DataCite members are responsible for updating and managing their DOIs and metadata. DataCite provides a number of services around DOI registration to maximize the benefits of DOI use. Read more about DOIs in DOI Basics.


A DOI name consists of a prefix and a suffix separated by a forward slash (e.g. 10.5438/9te8-5h68). Each organisation is assigned its own unique prefix(es). We recommend that each Repository has a single prefix to register DOIs. This can be assigned by the Member organization or by DataCite.


A DOI suffix must be unique within each prefix. The optimum length of a DOI suffix is 6–10 characters. This is long enough to ensure uniqueness, but short enough to avoid typing or text wrapping errors. The DataCite system will not accept DOIs longer than 255 characters. The easiest and recommended option is to use a randomly generated suffix. The auto-generated DOI strings use a-z, 0-9. They avoid i, l, o as they are easily mixed up with 0, 1. We group the suffix into blocks of 4, separated by a hyphen. You can generate a random suffix in both Fabrica and the API and your DOI will look something like this 10.5438/9te8-5h68.


The auto-generate DOI name functionality means the DOI suffix is generated automatically and will look something like this 10.15138/33bv-s284.

We recommend avoiding human-readable information in a DOI suffix. Any meaning you put in to the DOI may change over time and become meaningless or even misleading. For further advice on DOI syntax, please see this DataCite blog post.

Registering your first DOI

To register DOIs you need a Repository account and a prefix. Please read our DOI registration policy before you start.

If you are new to DOI registration we recommend you practice registering DOIs in our test environment. The test environment works like a sandbox and nothing you do there will go live. Check out our guide to testing here. Once you move into the production environment, we recommend you consider using the "draft" state for DOIs, to avoid a situation where unwanted DOIs are registered.

DOIs can be registered using DataCite's web interface Fabrica or one of our APIs. You will find lots of information on the support site including information about DOI states, metadata examples, and best practices for landing pages.
