ORCID is used increasingly by publishers and funders to identify researchers, therefore we recommend you to create an ORCID profile. ORCID is an independent consortium of publishers, funders and research institutions.

ORCID is an effort of the scholarly publishing community to create unique identifiers for scientists and let them create a complete overview of their scientific career, including publication list, and use this to identify themselves to publishers and funders.

Getting started

You can add other personal identifiers to your profile (e.g. ScopusID, AuthorID, ScholarID, Mendeley) The most important section is the list of 'works' (i.e. publications).

How do I fill my ORCID?

You can fill your ORCID profile with publications from most of the above listed profiles. Below you find an overview of the options of each.

Do you have different profiles?

Your different profiles will usually contain references to the same works. So if you populate your profile from more than one service, duplicates may appear in your ORCID. If you use both Web of Science and Scopus, the ORCID registry will recognize and merge the duplicates because they have the same identifiers (like DOI or PubMed ID). If you transfer references from your Google Scholar or EndNote profile using BibTeX, ORCID will not recognize the duplicates even if the reference includes a DOI. You will have to remove these duplicates yourself.


If a researcher has authored a book or report that is in a library catalogue, he may very well have been assigned an ‘ISNI’. Authors can check if they have an ISNI. These profiles have usually been created by library organizations, authors do not have control over them. Publications that have an ISBN can be connected straightforwardly from the ISNI profile to the ORCID profile (to use this you should have created an ORCID profile first).

Keeping your ORCID up to date

You can choose to have your ORCID automatically updated when you publish new publications. To enable auto-updates, you need to do two things: use your ORCID iD when submitting an article or dataset (if the journal or data center collects ORCID iDs), and authorise Crossref and DataCite to update your ORCID record.

You can authorise Crossref and DataCite as follows:

  • Crossref: On the Crossref website, click the green icon with the letters ‘ID’ in the right upper part of the page, and fill out the form.
  • DataCite: On the DataCite website, click ‘Sign in with ORCID’ in the upper right corner, and fill out the form.

In case you change your mind, you can revoke permission for auto-updates at any time.

Technical information

Technically an ORCID is an ISNI. Both schemes use the same 16-digit format and the ISNI organization has reserved a range of identifiers for ORCIDs. But there are two different registries for ISNI and ORCID that serve different communities. The ORCID registry serves the scientific community only, while the ISNI registry serves the creative industry (e.g. creators of books, movies, music).
