An ORCID iD (Open Researcher and Contributor ID) gives you a way to reliably, unambiguously and permanently connect your names(s) with your work throughout your research career, including publications, grants, education, employment and other biographical information, etc
Following are the reasons why do journals require researchers to have an ORCID.
1.Uniquely identify yourself within the global research landscape with ORCID.
2.Stand out from the crowd. Your ORCID iD ensures proper attribution of your work throughout your career.
3.Demonstrate impact. Your ORCID iD connects you with your scholarly research and makes it easier to find through enhanced author and contributor listings.
4. Get it all in one place. ORCID supports automated linkages between researcher and professional activities and facilitates proper attribution of your work.
5.Take charge of your researcher profile. You control your privacy settings and who can see your record.
6. Don’t be left behind. Many publishers and grant-funding organizations are using ORCID iDs to connect people, places, and things in research workflows.
7. Simplify workflows. ORCID connects you with publishers, grant funders, repositories, higher education institutions, professional associations, and other identifiers.
8. Enter once, use often. Information from your ORCID record can be pulled into and across multiple systems.
