A Guide to APA In-Text Citation with Page Numbers
When writing a research paper or academic essay, accurately citing sources is crucial for maintaining credibility and avoiding plagiarism. The American Psychological Association (APA) style is widely used in social sciences, education, and business fields, and its in-text citation guidelines can be a bit tricky to master, especially when it comes to including page numbers. In this article, we'll break down the basics of APA in-text citation with page numbers, providing you with a comprehensive guide to help you format your citations correctly.
Why Use In-Text Citations with Page Numbers?
In-text citations are used to acknowledge the work of other researchers and scholars in your writing, while also providing readers with a way to locate the sources you've referenced. Including page numbers in your in-text citations is essential when citing specific passages or quotes from a source. By doing so, you're enabling readers to easily locate the relevant information and verify the accuracy of your claims.
Basic In-Text Citation Format
The basic format for in-text citations in APA style involves including the author's last name, publication year, and page number(s) in parentheses at the end of the sentence or quotation. The format is as follows:

- Lastname, Year, p. Page number(s)
- Example: Smith, 2020, p. 12
However, when the author is unknown, you can use the title of the source in the parenthetical citation instead. For example:
- Title, Year, p. Page number(s)
- Example: (APA, 2020, p. 25)
Citing Multiple Authors
When citing multiple authors in APA style, you'll need to use the ampersand (&) symbol to separate the authors' names in the in-text citation. For example:
- Lastname, First initial. Lastname, First initial. Year, p. Page number(s)
- Example: Smith, J. & Johnson, K., 2020, p. 10
For three or more authors, you can use an ampersand before the last author's name, followed by "et al." in the in-text citation. For example:

- Lastname, First initial. Lastname, First initial. Lastname, First initial. et al. Year, p. Page number(s)
- Example: Smith, J. Johnson, K. & Williams, D. et al., 2020, p. 25
Citing Authors with the Same Last Name
When citing authors with the same last name, you'll need to include the first initial of each author's name in the in-text citation to avoid confusion. For example:
- Lastname, F. I. & Lastname, F. I. Year, p. Page number(s)
- Example: Smith, J. & Smith, K., 2020, p. 12
Citing Multiple Sources in One In-Text Citation
When citing multiple sources in a single sentence or quotation, you can use multiple sets of parentheses in APA style. For example:
- Lastname, Year, p. Page number(s); Lastname, Year, p. Page number(s)
- Example: Smith, 2020, p. 12; Johnson, 2019, p. 20
Alternatively, you can list the sources in the same order as they appear in the reference list. For example:
- Lastname, Year; Lastname, Year;...
- Example: Smith, 2020; Johnson, 2019
Citing Sources with No Author or No Page Number
When citing sources with no author or no page number, you can omit the author's name or page number in the in-text citation. For example:
- Title, Year
- Example: (APA, 2020)
Or:
- No author, Year, p. Page number(s)
- Example: No author, 2020, p. 10
