ORCID - Researcher Identifier

ORCID logo

ORCID (Open Researcher and Contributor ID) is an organization that assigns permanent numerical identifiers to uniquely identify individual researchers and their work. ORCID reaches across all disciplines, research sectors, and national boundaries. ORCID iDs are also used to create and maintain research profiles, as well as in manuscript submissions, grant applications, and patent applications.

Over 3,000,000 researchers worldwide have registered with ORCID as of April 2017.

ORCID is funded by institutional members, including the Georgetown University Library.

What is an ORCID iD?

An ORCID iD is a 16-digit numbers assigned by the ORCID Registry free of charge to individual researchers. Your ORCID iD is a unique identifier that is attached to your research so that all of your work is connected to you, regardless of how your name appears and whether other researchers have the same or similar names.

Why should I have an ORCID iD?

With an ORCID iD, there will be no ambiguity in what works are yours. You will use the same ORCID iD throughout your career regardless of any change in your name, institution, country, field of study, etc. Your ORCID iD is associated with your ORCID record which includes information about your professional work.

In addition to resolving any issues with name ambiguity in your research and writing, your ORCID iD may be recommended or required for manuscript submissions and grant applications. ORCID iDs also integrate into other research systems, products, and tools.

How do I get an ORCID iD?

Registering for an ORCID iD is quick and easy:

  1. Go to ORCID's Register for an ORCID iD page
  2. Complete the online form (name, email address, password, and your privacy setting)
  3. Accept ORCID's privacy policy and conditions of use
  4. Check your email for a verification message with your ORCID iD and a link to your ORCID record
  5. Click on the "Verify your email address" button to complete

What should I do after I get my ORCID iD?

Add professional information to your record: In addition to having a unique way to identify yourself as a researcher, your ORCID iD is also linked to your ORCID record, which contains your name, as well as education, employment, publications, and funding history. Once you have your ORCID iD, we recommend that you update your ORCID record with your Georgetown affiliation and Georgetown email address. If you are new to Georgetown and already have an ORCID iD, we recommend that you update your record with your current contact information. You can add additional information by clicking on the appropriate add some now links. 

Add publications to your record: For publications, ORCID works with Web of Science's ResearcherID, CrossRef, MLA International Bibliography, and Scopus to simplify the process of linking your ORCID iD to information in their databases. (Note: Georgetown University Library does not have a subscription to Scopus). To use the ORCID tools for integrating publications, login to your ORCID record, and click on add some now in the Works section. Read more about integrating your works with ORCID in their search and link tools.

For publications and other works that cannot be not linked through the ORCID tools, you can add records manually by logging into to your ORCID record, clicking on Add works, and Add manually. When prompted, enter information about each work you want to link to your ORCID iD. ORCID supports works ranging from books and articles to artistic performances, patents, data sets, and conference. View the complete list here.

Consider adding a delegate to update your record: You can add a "trusted individual" to your ORCID record to allow another person to update it with your latest publications, grants, etc. Read more about trusted individuals here.

Why should I use ORCID and not another author identifier?

ORCID is the only author identification system sponsored by an independent non-profit organization and not tied to a publisher, corporation, or government agency.

If you prefer to use more than one author identifier system, you may register with other systems as well - they are not mutually exclusive. Several author identification systems, such as ResearcherID and SciENcv, have integrated ORCID iDs into their systems to allow information from flow from one system to another.

Is there anything else I should know about ORCID iDs?

  • Do not create multiple ORCID iDs by signing up with different email addresses. This creates confusion in the ORCID system and makes it difficult to maintain and update your profile.
  • The Georgetown University Library supports ORCID's mission to address the name ambiguity problem in scholarly communication. Without memberships from the research community, ORCID would not be sustainable.
  • Read more from ORCID on how to make the most of your ORCID iD.
