The authors are required to provide their ORCID numbers at submission whenever available.

What is ORCID?
ORCID is the provider of a persistent digital identifier that is unique to you. This distinguishes you from every other researcher, which is important when others have the same or similar names. Through integration in manuscript submission it supports automated linkages between you and your professional activities ensuring that your work is recognized.

Getting an ORCID iD is free, quick and easy to do through the ORCID registration page: https://orcid.org/register

What are the benefits for authors having an ORCID iD?
There are often many researchers who have the same name, there are also researchers who may change their name or publish under different names during their career. With an ORCID iD, you will be correctly linked with your research work. And, if you use your ORCID iD during the submission process, and grant Crossref permission, we will update your ORCID record whenever you publish an article with us.

How can I include my ORCID iD in my profile?
You can enter it from your User interface after logging in >>View Profile >> Public.

Authenticated ORCID iDs that we collect will be included in the articles metadata. This will trigger the Crossref auto-update functionality. Crossref will send a notification to your ORCID inbox requesting permission to update your ORCID record with your published article. Please see https://www.crossref.org/community/orcid for more information.
