ORCiD is a unique identifier that allows you to tie all your research in one place.
Your unique ORCiD ID will belong to you throughout your scholarly career. It's a persistent identifier to:
Your ORCiD belongs to you and not to the University
More and more funding organisations, professional bodies and publishers are using ORCID iDs, with support from external funding bodies like JISC and ARMA.
This means you can often use your ORCID iD instead of manually submitting personal and citation information. This makes grant submissions easier and means you don't have to repeatedly enter the same information into various systems.
Go to the ORCID website: https://orcid.org/ and look yourself up. If you aren't there, register - it takes 30 seconds.
