When journals require an ORCID iD, and who has to have one.

Sometimes, and it depends on the publisher. A growing number of journals will not let the corresponding author finish a submission until an authenticated ORCID iD is attached, while most treat co-author iDs as optional. A smaller group requires one from every named author before the manuscript moves at all. If your target journal asks for none, you can still submit without one, though registering takes about ten minutes and saves you a scramble at the worst possible moment.

An ORCID iD is a free sixteen-digit identifier, written 0000-0000-0000-0000, that ties everything you publish to one verified record of you. The question below is who has to supply it, and when the submission system stops accepting excuses.

Which journals require an ORCID iD, and for whom?

The requirement comes in two shapes. The common one falls on the corresponding author alone; a minority of publishers require an iD from every author, and sometimes from reviewers and editors as well.

The corresponding-author version is the one you will meet most often. Cambridge University Press states it plainly: "Many of our journals now require the corresponding author of an article to submit an ORCID ID before they can submit their paper." Co-author iDs at Cambridge stay optional, added later through each author's own account. The Royal Society set this pattern in January 2016, when it became the first UK publisher to require an iD from every corresponding author, and seven other publishers committed to the same rule that year.

The stricter version reaches everyone whose name touches the paper. IOP Publishing puts it this way: "All researchers associated with IOP Publishing's journals need to have an Open Researcher and Contributor ID (ORCID) identifier (iD) associated with their ScholarOne account," and the policy names co-authors, reviewers, board members, and editors-in-chief alongside the submitting author. JMIR runs a similar rule, requiring an iD not only from the corresponding author but from every coauthor. So the question is not only whether your journal wants ORCID, but which of the two policies it runs. The author guidelines say which.

What does the submission system actually block without an iD?

It blocks the author step, not the file upload. On a corresponding-author mandate the portal will not let you pass the page where you confirm authors and affiliations until your own iD is attached, and it leaves the co-author fields open. On an all-author mandate, each author record needs a linked iD before the same page will clear.

The block behaves like any other required field. A missing abstract or a blank affiliation stops you in the same way, and the system flags it early rather than at final submission, so you find out with time to fix it. Editorial Manager and ScholarOne, the two systems behind most journals, both surface a "connect your ORCID" button at that step.

One detail decides whether the connection counts. When the portal offers an ORCID sign-in, use it instead of typing the sixteen digits into a text box. Signing in returns an authenticated iD that the journal stores against your name; a typed number is unauthenticated, proves nothing, and invites a transposed digit. Most systems that mandate ORCID want the authenticated kind, which is exactly what the sign-in produces. Getting this right is one line on the wider first-submission checklist, and the cheapest line to clear.

How do you set up an ORCID iD in ten minutes?

Register at orcid.org, add the parts of your record that identify you, and set those parts to public. The account is free and stays free for your whole career.

For a first-time author, a workable order is to register with an email you will keep past graduation, list every spelling your name has appeared under, add your current affiliation, and set visibility to everyone for the identifying fields. A record nobody can read cannot vouch for you. That is the short version; the full walk-through for first-time authors covers each field and the traps around institutional email. The point worth repeating here is that you do this once, not once per submission.

Does an ORCID iD fix inconsistent spelling of your name?

For the databases, yes. The same sixteen digits attach to every paper you publish, so the spelling on the byline stops deciding which record the paper lands in. The iD does not standardize how your name is printed; it links the variants under one number.

This matters more for some authors than others. A name crossing from Arabic script into Latin script has no single correct spelling, so indexes treat each version as a separate person. محمد reaches print as Mohammed, Muhammad, Mohamed, and Mohamad, and all four are legitimate and all four index apart. Add a dropped "Al-" prefix here, a reordered given name there, and an author a few papers into a career can hold two or three partial records, none of them complete. The iD is what makes the spelling stop mattering to the machine reading the byline. The deeper version of that problem, and what to put in your record to counter it, sits in the transliteration section of the setup guide.

Linking past papers so your record survives name variants

A fresh iD connects nothing on its own. To collapse the scattered versions of your name into one list, you have to add your existing publications to the record, and that is a separate step from registering.

Sign in, open Works, and choose "Add works". The search-and-link wizards pull your papers from sources like Crossref and Scopus, matching on your name and existing identifiers; you confirm which results are yours and the works attach to your iD. For anything the wizards miss, a thesis or a conference paper, add the DOI by hand or import a BibTeX file exported from your reference manager. Once a paper is on the record, its byline spelling no longer decides whether the world can find it under your name.

Settling who wrote the paper is a ten-minute task you finish once. Whether the manuscript itself meets the target journal's rules, from abstract length to reference style, is the separate check that repeats with every submission, the one Waraq runs by reading your file against the journal's rule set and returning each fix as a tracked change in Word. Set up the iD this week, link your past papers while you are in there, and the ORCID line on your next submission form takes ten seconds instead of a lost evening.
