A DOI is a unique alphanumeric string provided by a registration body (the International DOI Foundation) to identify material and establish a persistent connection to its location on the internet. When your paper is published and made available electronically, the publisher provides a DOI to it. This number serves as a pointer to the article, like a street address for online resources.
There are two types of DOIs: persistent and transient. A persistent DOI remains valid even after an article is revised or removed from circulation. A transient DOI becomes invalid if the article is deleted from the original publication site or if the publication site is changed without prior notification. Transient DOIs are useful for pointing to information that may be relevant but no longer available online.
In addition to pointers to articles, some databases provide DOI services that go beyond simple identification. For example, CrossRef uses DOI's to link data sets that it indexes; these links remain valid even if the underlying documents are updated or removed.
Many journals now require their authors to assign DOI's to their papers when they submit them. The purpose is to make it easier for others to find and read old papers. Publishers hope that making articles searchable will also increase citations of those articles.
So, as you can see, a DOI is a unique identifier given to an article so that it can be easily found and referenced later.
The DOI system offers a technological and social framework for registering and using persistent interoperable identifiers (DOIs) for usage on digital networks. Determine a DOI name: Enter a DOI name, such as 10.1000/xyz123, into the text box below. The DOI Name Resolver tool returns a list of possible names.
The URL or DOI (Direct Object Identifier) of an online source is added at the end of an APA citation. DOI numbers are often generated by publishers for journal articles and other periodicals. They were established to address the issue of broken or obsolete links and URLs. Using DOI's allows readers to quickly find any article they may be interested in that has been published in recent years.
In addition to journal articles, books also have a unique identifier called the ISBN number. This number is used to identify specific editions of a book series or writers within those series. Like DOI's, ISBN's were created to make it easier to locate articles about topics within those books or series. A library will use these numbers when placing an order through its inter-library loan system to ensure that the material it sends back contains exactly what the borrower requested.
APA requires researchers to provide full citations for all references made in their papers. These include books, journals, magazines, newspapers, websites, databases, and even film and television programs. Within these citations, authors should include the publisher's identification number if available. This helps others find works related to your topic.
References are pieces of information that help readers understand evidence or information presented in a paper. They are required in every academic paper except opinion pieces. The two main types of references are primary and secondary.
If a DOI (digital object identifier) is available for a publication, always include it in an APA journal citation. If an article does not have a DOI and you obtained it via a database or in print, just omit the DOI. The information is used by libraries to identify articles that are new or updated.
In addition to being included in your reference list, the DOI can also be entered into citation databases such as Scopus or Web of Science. These databases use the DOI to identify relevant articles published in journals covered by your bibliography or research project. This means that including the DOI in your references will help other scholars find relevant articles written by our authors!
DOIs were first introduced by the National Library of Medicine (NLM) in 2002. Since then they have been adopted by many other publishers. A persistent DOI remains valid even after an article has been revised or removed from the website. A transient DOI is valid only while the article is posted on the publisher's website. For example, an article with a transitive DOI can be referenced by its unique identifier until it is deleted from the website. Once this happens the DOI becomes invalid and another one is issued by the publisher.
Persistent and transient DOIs have their advantages and disadvantages.
DOIs play an important role in the APA 7th edition citing style, and if a book, journal, report, or other publication has one, it must be mentioned in the reference.
If your journal article was acquired from a subscription-based research database and does not have a DOI, offer just the author, date, title, and periodical information, which implies the reference terminates with the page range (American Psychological Association, 2020, p. 299). For instance, lastname, A. N. (2020). How do you cite a paper with no DOI in APA? Psych Central.

If your article was published in an open access journal with an ISSN or ISBN, you can use this as a unique identifier for the article. For example, lastname, A. N. (2020).
If your article was published in a print journal with no online version, you can use this as a unique identifier for the article.
