It is advisable for researchers to register for both ResearcherID and ORCID
ResearcherID provides a solution to the author ambiguity problem within the scholarly research community. Each member is assigned a unique identifier to enable researchers to manage their publication lists, track their times cited counts and h-index, identify potential collaborators and avoid author mis-identification. In addition, your ResearcherID information integrates with the Web of Science and is ORCID compliant, allowing you to claim and showcase your publications from a single one account. Search the registry to find collaborators, review publication lists and explore how research is used around the world!
ORCID provides a persistent digital identifier that distinguishes you from every other researcher and, through integration in key research workflows such as manuscript and grant submission, supports automated linkages between you and your professional activities ensuring that your work is recognized.

Why do you need both identifiers?Even if a researcher has an existing ORCID through another resource, it’s important that it be linked to his/her ResearcherID profile for a proper trail of information down the road. ResearcherID is the primary place where Times Cited data in the Web of Science™ Core Collection appears, thus underscoring the importance of having both identifiers, and having them connected (ResearcherID and ORCID).
