ISSN: International Standard Serial Number (ISSN) is a unique number used to identify a print or electronic periodical (journal) title. DOI: Digital Object Identifier (DOI) is used to uniquely identify online objects such as journal articles or data sets.

Can I use ISSN instead of DOI APA?

It is strongly recommended that publishers use the ISSN number as part of the title-level DOI they use to offer a persistent and resolvable link to their journal. A DOI is the identifier of an entity—physical, digital or abstract.

How DOI find the DOI of a journal?

In most scholarly journal articles, the DOI will be printed with the article itself, usually on the first page somewhere: below the title or in the header or footer. If the DOI isn't included in the article, look it up on the website CrossRef.org (use the "Search Metadata" option) to check for an assigned DOI.
