Author Identification using ORCID

It is important to be able to clearly identify authors of publications. Examples for the need of unambigious identification are authors with the same name, name changes, and when authors change institutions. This unambiguous identification is required to be possible both for individuals when reading a publication and for computers. Unambiguous numeric identifiers, which authors state in addition to their names and instutions (affiliation), have become standard.

Most used are the identifiers of ORCID. These allow adding infomation about affiliation, publications, research data and academic positions. Humboldt-Universität zu Berlin is an official member of ORCID and supports the use of their identifiers. All scientists of Humboldt-Universität are encouraged to register at ORCID and use their inidividual identifier when publishing or submitting grant applications, and in similar cases.

ORCID's logo

ORCID is an organisation that assigns non-proprietary and unambigious identifiers for individuals from science and research. The assigned identifier (also called ORCID iD; originally derived from 'Open Researcher and Contributor ID') consists of 16 digits displayed as blocks of fours (example: 0000-0002-1825-0097). As part of a web address it links to the ORCID profile of a person, which can hold further information about that person and which is independent of the person's institution. The use of ORCID has become an international de facto standard for the identification of authors.

How to register and create a profile

  1. Registration of an unambigious identifier at ORCID in a few steps
  2. Adding information to the ORCID profile, connecting other identifiers (such as Scopus Author ID or Researcher ID) if existent, setting privacy preferences for the entire profile or individual pieces of information
  3. Creating a list of one's publications by import (for example from Google Scholar, Web of Science, CrossRef, BASE) or by manual addition
  4. Using the registered identifier (the ORCID iD) on one's own website, when submitting grant applications or manuscripts, on one's business card, and so forth


  • unambigious identification of a person (also in the case of multiple persons with the same name, name changes, or differing spelling of a name)
  • unambigious attribution of biography and individual research output (such as publications, research data, software)
  • automated creation of publication lists (optional)
  • data privacy
  • easier communication with research funding institutions, academic societies, publishers and repositories (for example when submitting grant applications or manuscripts, or when registering for a conference)
  • simplified monitoring of research outputs of universities, departments, institutes and research groups

Data privacy

Privacy of data is an essential principle of ORCID. Users have full control over which information they add and over which information is visible for only oneself, trusted parties or the public. Only the name and the identifier (the ORCID iD) are always visible publicly.

Further information

Further information and support for using ORCID can be found on ORCID's official website and on the website of the project ORCID DE which promotes the use of ORCID in Germany.

Furthermore, the website of Charité lists answers to frequently asked questions about ORCID.

Use at Humboldt-Universität

At Humboldt-Universität the use and display of an ORCID iD is integrated on the repository (edoc-Server) and the research information system. It is also possible to log-in to ORCID via a HU account. Other applications are in preparation.
