In the scientific world, where hundreds of new studies appear every day, it is important not only to create a scientific product, but also to clearly identify the author. Surnames can coincide, transliteration changes, and people change institutions several times during their careers. That is why ORCID has become one of the key tools for modern scientists.

What is ORCID?
ORCID (Open Researcher and Contributor ID) is a digital identifier that uniquely identifies each researcher in the global environment. It works as a digital passport for researchers, making it easy to find all their work, regardless of where and when it was published.
The ORCID.org platform allows you to create your own profile, add publications, places of work, funded projects, and other achievements. It is a convenient database controlled by the researcher themselves.
ORCID is not just another profile. It is a unique identifier that helps systematise a researcher's career path and increase their visibility in the international scientific community. Every year, more and more journals and grant programmes are making it a mandatory part of the scientific ecosystem.
What does ORCID look like?
ORCID is a 16-digit identifier divided by hyphens into four blocks of four characters (format: 0000-0000-0000-000X) and is represented as a URL.
Some people have questions about the composition of the number, as the last character may not be a digit. This is a checksum calculated according to the international standard ISO/IEC 7064:2003, MOD 11-2. It can have a value from 0 to 9 or ‘X’ (capital letter), which means 10.
Why do researchers need ORCID?
In modern systems, ORCID plays a much greater role than just a number. It allows you to:
- avoid confusion between authors with the same surname
- automatically pull data from scientific databases
- reduce the number of technical errors when submitting an article
- make your scientific profile more recognisable and professional
Importantly, ORCID is not just a tool for journals. It is also needed by universities, grant agencies, library catalogues, and other systems that evaluate researchers' scientific contributions.
What are the benefits of ORCID for researchers?
When ORCID is integrated into your work, administrative procedures become significantly simpler – from submitting grant applications to participating in international research initiatives. Using this identifier reduces the amount of manual work and synchronises data on scientific activity between different systems.
The main advantages include:
- Correct attribution of authorship.
- Automatic import of publications.
- Convenient and quick updating of the list of works.
- Possibility of integration with Google Scholar, Scopus, Web of Science.
- Increased trust from editorial offices and scientific institutions.
The result is a comprehensive and always up-to-date scientific profile that is easy to use in both scientific communications and professional activities.
Today, ORCID is more than just a tool for organising publications. It is part of a scientist's professional identity, which enhances their authority, facilitates cooperation with international partners, and ensures the accurate reflection of scientific achievements.
Creating an ORCID and regularly updating your profile is a simple step that significantly improves the quality of scientific communication and opens up new opportunities for career development.
