Many journals request (but do not require) that authors provide their ORCID iD on manuscript files or within the online submission system. In recent years, however, the number of journals that outright require an ORCID iD has increased. Often journals and publishers require an ORCID iD for only the corresponding author, but some, such as JMIR Publications and ScienceOpen, require an ORCID iD for all named authors.
Today, over 7,000 journals are already collecting ORCID iDs from corresponding authors, up from over 1,500 in 2017. And this number is only going to increase. At the end of 2015, the ORCID website published an open letter where publishers can pledge their commitment to requiring ORCID iDs for authors. Within a year, 25 publishers and scholarly associations had signed this letter, 16 of whom had already implemented this requirement by the end of 2016. Now, over 90 publishers and journals have signed, including some of the largest in the industry, such as PLOS, Springer Nature, Wiley, and SAGE Publications. This list is being updated all the time (with new signatories as recently as August, 2020). You can view the full list of signatories here.
Publishers aren’t the only organizations that have started to implement ORCID. In fact, many funders now recommend or require the use of ORCID iDs in their grant application systems. A list of funders that have issued a policy or statement related to ORCID requirements can be found on the ORCID website.
There is strong support for the adoption of ORCID iDs by publishers and other professional societies within the academic community. A 2015 survey reported as high as 72% of respondents agreeing or strongly agreeing that ORCID requirements would be beneficial for the research community (compared with 21% neutral responses and only 7% disagreeing or strongly disagreeing).
