ORCID is a non-profit organisation which, among other things, provides researchers with an ORCID iD. An ORCID iD (Open Researcher and Contributor ID) is a persistent digital identifier.
Aarhus University encourages all its researchers to get an ORCID iD, but it is not obligatory.
An ORCID iD:
Use your ORCID iD in your auto signature, your Pure profile and your AU profile as well as for quick registration when submitting applications for funding.
This ensures that your research is discoverable and that you are recognised for it.
You can transfer data to your ORCID iD from other researcher ID such as ResearcherID and Scopus Author Identifier.
ResearcherID is a researcher ID from Clarivate Analytics (formerly Thomson Reuters) and an integral part of the Web of Science database. Therefore, an up-to-date ResearcherID is also an updated author profile in the Web of Science, and makes it easier to identify your publications and calculate your h-index (Hirsch index). It is possible to connect ResearcherID and the ORCID iD and transfer data to your ORCID.

Scopus Author Identifier is your author profile in the database Scopus and an integral part of the database. It is a good idea to ensure that your author profile is up to date, as it makes it easier to identify your publications and calculate your h-index.
It is possible to connect Scopus Author Identifier with ORCID iD and transfer data to your ORCID.
