APA Style is widely used by students, researchers, and professionals in the social and behavioural sciences. The Scribbr APA Reference Generator automatically generates accurate references and in-text citations for free.
This citation guide outlines the most important citation guidelines from the 7th edition APA Publication Manual (2020). Scribbr also offers free guides for the older APA 6th edition, MLA Style, and Chicago Style.

In-text citations are brief references in the running text that direct readers to the reference entry at the end of the paper. You include them every time you quote or paraphrase someone else’s ideas or words.
An APA in-text citation consists of the author’s last name and the year of publication (also known as the author-date system). If you’re citing a specific part of a source, you should also include a locator such as a page number or timestamp. For example: (Smith, 2020, p. 170) .
The in-text citation can take two forms: parenthetical and narrative. Both types are generated automatically when citing a source with Scribbr’s APA Citation Generator.
The in-text citation changes slightly when a source has multiple authors or an organization as an author. Pay attention to punctuation and the use of the ampersand (&) symbol.
| Author type | Parenthetical citation | Narrative citation |
|---|---|---|
| One author | (Smith, 2020) | Smith (2020) |
| Two authors | (Smith & Jones, 2020) | Smith and Jones (2020) |
| Three or more authors | (Smith et al., 2020) | Smith et al. (2020) |
| Organization | (Scribbr, 2020) | Scribbr (2020) |
When the author, publication date or locator is unknown, take the steps outlined below.
| Missing element | What to do | Parenthetical citation |
|---|---|---|
| Author | Use the source title.* | (Source Title, 2020) |
| Date | Write “n.d.” for “no date”. | (Smith, n.d.) |
| Page number | Either use an alternative locator or omit the page number. | (Smith, 2020, Chapter 3) or (Smith, 2020) |
