ORCID provides a permanent digital identifier that is unique to you. With this identifier, you can distinguish yourself from other researchers.
The ORCID initiative is open, non-profit, and community driven. It is also backed by large publishers such as Thomson Reuters and Elsevier, which means that the ORCID identifier can be connected with commercial products like ResearcherID and Scopus.

This saves you from having to enter the same data over and over again when submitting your work.
