If you publish a journal, magazine, newsletter, or any periodical publication in India, you have probably come across one requirement again and again: get an ISSN number. Whether you are an academic editor launching a research journal, a university department starting a departmental publication, or a magazine publisher going digital, ISSN registration in India is the identifier that makes your publication recognized, trackable, and indexable across the world.
This page explains exactly what an ISSN is, how to get an ISSN number for a journal in India, who is eligible, what documents you need, how much it costs, and what to expect at every step of the process.
What Is an ISSN Number?
ISSN stands for International Standard Serial Number. It is an 8-digit code displayed in the format XXXX-XXXX that uniquely identifies a serial publication such as a journal, magazine, newspaper, newsletter, yearbook, or any periodical that continues over time. Think of an ISSN like an Aadhaar number, but for a publication instead of a person. Just as an Aadhaar number identifies one individual uniquely across India, an ISSN identifies one specific publication uniquely across the entire world. No two publications ever share the same ISSN. ISSNs are assigned by the ISSN International Centre in Paris, but the actual assignment for Indian publications is handled through India's own national body the National Centre for ISSN, India, which operates from the National Science Library at CSIR-NIScPR (National Institute of Science Communication and Policy Research) in New Delhi.
A key detail many first-time applicants miss: a separate ISSN is required for each format of the same publication. If your journal is available both in print and online, you need two different ISSNs, one Print ISSN (p-ISSN) and one Online ISSN (e-ISSN).
