What is ORCID?

ORCID is a unique researcher-ID associated with your research activity.

If you enter ORCID when you submit manuscripts or applications it is easier to identify which research is yours. Your ORCID stays with you throughout your research career, even if you change your name, job, institution or move abroad.

Why use ORCID?

Using only names as identifiers in research contexts is not always unproblematic. Many persons have the same or a similar name. If everyone has an ORCID, Ole Olsen (Olsen, O) avoids being mixed with Oda Olsen (Olsen, O). ORCID makes it easier for you to change your name, job or institution. Your research is registered on your ORCID regardless of such changes.

Many databases containing scientific literature use ORCID. These databases can be used for calculating your h-index, among other things. That's why it is so useful to have an ORCID, as there will be no questions about whether it is your work that is included in the calculation. All citations are registered to you and you get the recognition you deserve even if the publishers have not spelled your name the same (Husøy, Husoy, Husoey).
