An '''International Standard Serial Number''' ('''ISSN''') is an eight-digit to [[unique identifier|uniquely identify]] a [[serial (publishing)|periodical publication]] (periodical), such as a magazine.<ref name=Whatis>{{cite web |url=https://www.issn.org/understanding-the-issn/what-is-an-issn |title=What is an ISSN? |publisher=ISSN International Centre |place=Paris |access-date=13 July 2014 |archive-date=16 July 2014 |archive-url=https://web.archive.org/web/20140716113932/http://www.issn.org/understanding-the-issn/what-is-an-issn/ |url-status=live }}</ref> The ISSN is especially helpful in distinguishing between serials with the same title. ISSNs are used in ordering, cataloging, interlibrary loans, and other practices in connection with serial literature.<ref>{{cite web |url=http://www.bl.uk/bibliographic/issn.html |title=Collection Metadata Standards |publisher=British Library |access-date=14 July 2014 |archive-date=15 July 2014 |archive-url=https://web.archive.org/web/20140715143822/http://www.bl.uk/bibliographic/issn.html |url-status=live }}</ref>

The ISSN system was first drafted as an [[International Organization for Standardization]] (ISO) [[international standard]] in 1971 and published as ISO 3297 in 1975.<ref>{{cite web |url=https://www.issn.org/understanding-the-issn/standardization |title=ISSN, a Standardised Code |publisher=ISSN International Centre |place=Paris |access-date=13 July 2014 |archive-date=16 July 2014 |archive-url=https://web.archive.org/web/20140716124242/http://www.issn.org/understanding-the-issn/standardization/ |url-status=live }}</ref> ISO subcommittee [[TC 46/SC 9]] is responsible for maintaining the standard.

When a serial with the same [[content (media)|content]] is published in more than one [[media (communication)|media type]], a different ISSN is assigned to each media type. For example, many serials are published both in [[Printing|print]] and [[electronic media]]. The ISSN system refers to these types as '''print ISSN''' ('''p-ISSN''') and '''electronic ISSN''' ('''e-ISSN''').<ref>{{Cite web|url=https://www.issn.org/understanding-the-issn/assignment-rules/the-issn-for-electronic-media/?lang=en|title=The ISSN for electronic media|last=ISSN InterNational Centre|website=ISSN|access-date=2020-04-03|archive-date=11 October 2017|archive-url=https://web.archive.org/web/20171011031921/http://www.issn.org/understanding-the-issn/assignment-rules/the-issn-for-electronic-media/?lang=en|url-status=live}}</ref> Consequently, as defined in ISO 3297:2007, every serial in the ISSN system is also assigned a '''linking ISSN''' ('''ISSN-L'''), typically the same as the ISSN assigned to the serial in its first published medium, which links together all ISSNs assigned to the serial in every medium.<ref>{{Cite book |date=January 2015 |title=ISSN Manual |publisher=ISSN International Centre |place=Paris |url=https://www.issn.org/wp-content/uploads/2013/09/ISSNManual_ENG2015_23-01-2015.pdf |pages=14, 16, 55–58 |chapter=3 |access-date=22 October 2018 |archive-date=12 July 2020 |archive-url=https://web.archive.org/web/20200712102227/http://www.issn.org/wp-content/uploads/2013/09/ISSNManual_ENG2015_23-01-2015.pdf |url-status=dead }} [https://www.issn.org/understanding-the-issn/assignment-rules/issn-manual HTML version available at www.issn.org] {{Webarchive|url=https://web.archive.org/web/20181018185939/http://www.issn.org/understanding-the-issn/assignment-rules/issn-manual/ |date=18 October 2018 }}</ref>
