ISSN Check

What are we checking?

An ISSN is a unique identifier for a journal. You can read more about ISSN's in our article titled What is an ISSN (International Standard Serial Number)?

This page enables you to make certain checks about an ISSN (i.e. a journal). At the moment, the page checks that the ISSN is recognized by ISSN (itself), DOAJ (Directory of Open Access Journals) and COPE (Committee on Publications Ethics).

How to do a check

You need provide the ISSN as part of the URL. That is; https://predatory-publishing.com/ISSNCheck/?issn=nnnn-mmmm, where "nnnn-mmmm" is an ISSN.

For example https://predatory-publishing.com/ISSNCheck/?issn=1234-5678 is a valid URL, although that journal does not exist. If you click the link, take a look at the URL, and you can see the ISSN is provided at the end of the URL.

INVALID ISSN

The ISSN you have supplied is not valid. Please bear in mind the following:

1. You need provide the ISSN as part of the URL. That is; https://predatory-publishing.com/ISSNCheck/?issn=nnnn-mmmm, where "nnnn-mmmm" is an ISSN. For example https://predatory-publishing.com/ISSNCheck/?issn=1234-5678 is a valid URL, although that journal does not exist. If you click the link, take a look at the URL, and you can see the ISSN is provided at the end of the URL.
2. An ISSN is of the form nnnn-mmmm, where nnnn = are four digits and mmmm is also four digits, although the last digit can be X (as it is a check digit). The middle character must be a hyphen.
