What is an ORCID iD?

Why a name is not enough

Names change with marriage, transliteration and preference, and the same name can belong to hundreds of people in one field. Initials make it worse: an abstract listing A. Singh could mean anyone. Databases try to guess which works belong together, and they guess wrong often enough that researchers find strangers' papers on their profiles. ORCID describes its iD as a unique, persistent identifier free of charge to researchers, and says the organisation is sustained by fees from member organisations rather than by researchers. Because the researcher owns the record, it follows them from a PhD to a postdoc overseas to a job outside universities without anyone having to merge profiles.

How the record fills itself

The iD on its own is only a number. Its value comes from what connects to it. When a journal, funder or university that supports ORCID asks for the iD at submission, it can write the paper, grant or role back to the researcher's record once the researcher gives permission. A researcher can also add works by hand or import them from databases. The record page, reached at orcid.org followed by the iD, lists employment, education, funding and works, with visibility set by the researcher. The published test record for a fictional researcher, 0000-0002-1825-0097, shows what a public record looks like without exposing a real person.

When it matters most

It matters at every point where credit is counted. Many journals ask the corresponding author, and sometimes every author, for an iD at submission. Funders use iDs to pre fill applications and to track outputs from a grant. Hiring and promotion panels use them to confirm a publication list without chasing each paper. For early career researchers the benefit is largest, because a short publication list scattered under variant spellings is easy to overlook. At a poster session it helps a visitor who wants to find the presenter's other work after the conference, when the name on the badge is all they remember.

Common mistakes with iDs

The most common is registering twice, once as a student and again years later, leaving two thin records instead of one full one; ORCID can help merge duplicates. Another is creating an iD and never connecting anything to it, so the link from a poster leads to an empty page. A third is printing the bare sixteen digits without the web address, which forces a reader to guess where to paste them. Some researchers also set everything to private, which protects them but defeats the purpose of a public link. Checking the record once a year and after each new job keeps it useful.

Where it shows up in the poster builder

On every one of the 40 poster layouts the author block holds names, an affiliation list with superscripts generated from it, and a marker for the presenting author. It has no field for an ORCID iD, so there is no built in place to print one beside each name. Two practical options follow. Put the presenting author's iD as a short line in a section near the conclusion, written as the full orcid.org address. Or encode a page that lists every author's record in the QR code, which 37 of the 40 layouts carry and which accepts a typed link or an uploaded QR image.

Choosing what to print

A poster has room for one short identity line, not a list of profiles. If the conference asks for iDs in the abstract system, the programme book usually prints them, and the board can stay clean. Where only one author will stand at the board, that person's iD is the one worth printing, because it is the one a visitor will look up. Scopus and Web of Science identifiers are rarely printed on posters, since they are tied to one database and change less under the researcher's control. A lab or project page behind the QR code can list every author's iD and stay current after the board is printed.
