What Is an ORCID iD? Why Researchers Need One Before Journal Submission
An ORCID iD (often searched for as “ORCID ID”) is a free, persistent 16-character identifier that distinguishes you from every other researcher, no matter how common your name is. Formatted as a URL such as orcid.org/0000-0002-1825-0097, it stays with you for your entire career, and a growing number of journals request it, and in some cases require it, from corresponding authors during manuscript submission. This guide explains what an ORCID iD actually is, why publishers ask for it, how an authenticated ORCID iD differs from one you simply type in, and exactly what to check before you submit.

Frequently Asked Questions Final Thoughts What Is an ORCID iD? ORCID stands for Open Researcher and Contributor ID. An ORCID iD is a free, persistent, name-independent identifier issued by ORCID, a global non-profit organization, specifically to solve the problem of name ambiguity in research. It is sometimes called an ORCID number, or referred to more generally as an author identifier or a digital identifier for researchers, though ORCID’s own branding uses “ORCID iD,” with a lowercase i and uppercase D, a distinction explained in ORCID’s own guide to what an ORCID iD is. Technically, an ORCID iD is a 16-character code, not strictly a 16-digit number, because the final checksum character can be either a digit or the letter X. In practice this rarely matters, but it is the more accurate description if you are citing the identifier’s format. Anyone who might find an ORCID iD useful can register for one. There is no requirement to hold an institutional affiliation and no formal test of who “qualifies” as a researcher; the registry is open to authors, reviewers, students, and other contributors to the research process. What Problem Does an ORCID iD Solve? The core problem is name ambiguity. Common names, name changes after marriage or transliteration, and inconsistent formatting across databases- for example, Sofia Maria Hernandez Garcia appearing as S. Hernandez in one journal and Sofia M. Garcia in another- all make it difficult for publishers, funders, and indexing databases to reliably connect one researcher to their complete body of work. An ORCID iD helps resolve that ambiguity by providing a persistent reference point that stays attached to you regardless of how your name is written, where you work, or how many times you change fields or institutions. What Can Your ORCID Record Do for You? Your ORCID record is the profile of information connected to your ORCID iD. Once it is set up and connected to the systems you use, it can: Help ensure your research outputs and activities are correctly attributed to you Connect your affiliations, funding, peer review activity, and publications in one place Reduce repetitive form filling, since information entered once can be reused across connected systems Improve the discoverability of your work for potential collaborators and readers Stay with you through changes in name, employer, location, or field of study Note: an ORCID iD reduces attribution errors and streamlines data reuse; it does not guarantee that every external database will always display your information correctly, since that also depends on the integrations and permissions you set up. Why Do Researchers Need an ORCID iD for Journal Submission? Journals increasingly build ORCID collection into their manuscript submission systems for a few practical reasons. It gives editors and publishers a reliable way to confirm who submitted a paper, separate from name spelling or institutional email changes. It lets submission systems auto-populate profile fields such as name, affiliation history, and past publications where an integration exists, saving authors time on repetitive entry. And it gives funders and institutions a consistent way to track research output linked to a specific person rather than a name string that might match several people. Do All Journals Require an ORCID iD? Not universally, and requirements vary by publisher and sometimes by individual journal within the same publisher’s portfolio. A number of major publishers were early adopters of formal ORCID requirements for corresponding authors, including IEEE, Springer Nature, Wiley, PLOS, SAGE, the American Chemical Society, and JMIR Publications, among others, according to ORCID’s own publisher adoption record, and thousands of journals now collect ORCID iDs from corresponding authors through their submission systems. That said, the specific rule, whether it applies to the corresponding author only or to every co-author, and whether it is mandatory or simply requested, differs from journal to journal. The safest approach is to check the target journal’s own “Instructions for Authors” or submission guidelines before you assume either way. If you would rather have that confirmed for you alongside the rest of your journal shortlist, our Journal Selection Service cross-checks a manuscript’s scope against journal requirements, ORCID policy included, before you commit time to formatting and submission. ORCID iD vs ORCID Record vs Authenticated ORCID iD These three terms get used loosely, but they mean different things, and the third one is exactly the distinction most beginner guides skip. ORCID iD: the identifier itself, the 16-character code and URL that is uniquely yours. ORCID record: the profile of data connected to that iD, including your affiliations, works, and funding history. Authenticated ORCID iD: what happens when you sign in to ORCID directly inside a publisher’s submission system and grant it permission to read or write to your record, rather than typing your iD into a text field.
