What is ISSN?

International Standard Serial Number (ISSN) is an international identifier for serials and continuing resources in the electronic and print worlds. It can be assigned to any serial or continuing resource whether past, present or to be published in the foreseeable future whatever the medium of production (e.g. print, online, CD-ROM, etc.).

An ISSN is not mandatory, and does not convey any form of legal or provide copyright protection on a work.

What is a publisher?

The publisher is the group, organization, company or individual who is responsible for initiating the production of a particular publication. Normally, the publisher is also the person or body who bears the cost or financial risk in making a product available.

How much does it cost?

Per Public Advisory No. JET-02 dated November 11, 2022, application for ISSN is FREE OF CHARGE.

Do I need a different ISSN for each format?

Each format must have a different ISSN, which means that if you have one serial or continuing resource but will be published in different formats, e.g. print, online or CD/DVD, each of these will have its own ISSN.

A new ISSN may only be applied for in the following cases:

  • The publication’s medium changes (e.g. a print becomes an online)
  • The publication’s title changes
  • Different language editions


    Any changes made in the publication must be mentioned in detail with regards to the old title, ISSN and frequency during the application of the new title.

      What is a serial?

      Serial is a continuing resource in any medium, issued in a succession of discrete parts, usually bearing numbering, that has no predetermined conclusion.  Examples of serials include journals, magazines, electronic journals, ongoing directories, annual reports, newspapers, monographic series, and newsletters.

      What are Ongoing Integrating Resources?

      Ongoing integrating resources are electronic publications that are continuously updated, such as websites, blogs, institutional repositories, directories, and databases.
