How do I get identifiers for my data?
Use EZID – a service managed by the UC Curation Center and paid for by the UC San Diego Library to assign Digital Object Identifiers (DOIs) that persistently link to your data. The EZID service allows you to register and cite permanent identifiers for your datasets. Automated workflows are available with EZID's application programming interface (API).
For more information and to register for a UC San Diego EZID account, contact Research Data Curation Program
Why assign an identifier to my data?
- becomes an integral part of your data citation
- enables easy reuse and locating of your data by others
- allows the impact of data to be tracked
- creates a scholarly structure that recognizes and rewards data producers
- strengthens your Data Management Plan for naming and organizing your research results
How do I get an identifier for myself?
The ORCID Registry is available free of charge to individuals, who may obtain an ORCID identifier, manage their record of activities, and search for others in the Registry.

Why establish a personal identifier?
The Library Research Data Curation Program recommends that you obtain a unique researcher identifier through ORCID (Open Researcher and Contributor ID).
ORCID provides you with a persistent digital identifier that distinguishes you from every other researcher and, through integration in key research workflows such as manuscript and grant submission, supports automated linkages between you and your professional activities.
- ensure that your work is recognized; facilitate disambiguation between your name and those that are similar
- enhance the scientific discovery process
- improve the efficiency of research funding
- strengthen collaboration within the research community
What are digital identifiers?
An identifier establishes an association between a character string and an object. Objects can be data files, publications, electronic resources, web pages, names of persons or organizations, and even physical objects. The character string is a unique set of characters assigned by a registration agency that identifies the object on a digital network.
A "persistent identifier" is an identifier that is available and managed over time; it will not change if the object is moved or renamed and the object can be reliably referenced for future access by humans and software.
Digital Object Identifiers (DOIs) are in widespread use for journal articles and are increasingly utilized as a means of precisely identifying specific datasets.
Here are some examples of identifiers and their use in citations:
