How do I cite a source with no page numbers in APA Style?
When you quote or paraphrase a specific passage from a source, you need to indicate the location of the passage in your in-text citation. If there are no page numbers (e.g. when citing a website) but the text is long, you can instead use section headings, paragraph numbers, or a combination of the two:
(Caulfield, 2019, Linking section, para. 1).
Section headings can be shortened if necessary. Kindle location numbers should not be used in ebook citations, as they are unreliable.
If you are referring to the source as a whole, it’s not necessary to include a page number or other marker.
