IEEE Citation Format: Rules, Examples & Templates
Your bibliography
0 sourcesIEEE Citation Format uses bracketed numbers like [1] in the text, matched to a numbered reference list in the order sources first appear. Each entry lists author initials, title, source, and publication details in a fixed order.
How does IEEE citation format work?
IEEE is a numeric citation system. You place a bracketed number in the text at each citation, and that number points to one entry in a reference list ordered by first appearance, not alphabetically. The first source you cite is [1], the second is [2], and each source keeps its number every time you reuse it.
This differs sharply from author-date styles. There are no surnames or years in the running text, and the reference list is never alphabetized. IEEE dominates electrical engineering, computer science, and related technical fields precisely because the compact brackets keep dense equations and prose readable.
What are the parts of an IEEE reference?
A journal reference is the clearest model. Author initials come before the surname, the article title sits in quotation marks, the abbreviated journal title is italicized, and the volume, issue, pages, and date follow in a set sequence. A DOI closes the entry when available.
“Adaptive filtering in nonlinear systems,”
IEEE Trans. Signal Process., vol. 67, no. 4, pp. 1023–1035,
Apr. 2019,
doi: 10.1109/TSP.2019.2901234.
- Number & authors — bracketed number, then initials before each surname; “and” joins the last two.
- Article title — in quotation marks, sentence case, comma inside the closing quote.
- Source — italic abbreviated journal title, then volume, issue, and page range.
- Date — abbreviated month and year of publication.
- DOI — lowercase
doi:followed by the identifier, ending the entry.
How do IEEE in-text citations work?
You cite by inserting the reference number in square brackets on the text line, before any punctuation and with a space in front. The bracket can act as a noun, so “as shown in [3]” and “the method in [3] fails” are both correct, and you never write “reference [3]” as “Ref. [3]” mid-sentence unless it opens the sentence.
Reuse the same number every time a source returns. Cite several sources as [2], [5], [7], and cite a consecutive run as [4]–[6]. Never bundle them as [4, 5, 6]. Because numbering follows first appearance, adding a new mid-paper citation renumbers everything after it, which is why a generator saves real time.
| Situation | In-text form |
|---|---|
| Single source | The results in [1] confirm this. |
| Two separate sources | Similar gains appear in [1], [4]. |
| Three or more in a run | Earlier work [2]–[5] disagrees. |
| Source as sentence subject | Reference [6] introduced the model. |
| Reusing a cited source | Return to the same [1] later. |
How do I cite common sources in IEEE?
Every source type reorders the same building blocks. Article and chapter titles take quotation marks; journal, book, and proceedings titles are italicized. Below are copy-ready references using realistic details you can adapt.

How do IEEE author names and titles work?
List authors as first and middle initials followed by the surname, such as “J. K. Reynolds.” Separate names with commas and join the final two with “and.” When a work has more than six authors, give only the first author’s name followed by et al., with no comma before it.
Capitalization is precise. Article, paper, and chapter titles use sentence case inside quotation marks. Journal, book, and proceedings titles use title case and italics, and journal names are abbreviated using the official IEEE abbreviation list, for example IEEE Trans. Signal Process. rather than the full spelled-out name.
| Element | IEEE treatment |
|---|---|
| Author name | Initials first: A. B. Chen |
| Seven or more authors | First author + et al. |
| Article / chapter title | “Sentence case in quotes,” |
| Journal / book title | Title Case in Italics |
| Month | Abbreviated: Jan., Feb., Mar., Apr. |
| Reference order | Order of first citation |
How accurate is this, and what are the limits?
These rules reflect the current IEEE Reference Guide, but IEEE style has real edge cases this page cannot fully cover. Journal title abbreviations are set by an official list, so an uncommon journal may need a direct lookup, and preprints, datasets, patents, and software each carry their own entry patterns.
Publisher templates also vary slightly. Some IEEE conferences request a DOI on every entry, some omit page ranges for online-only articles, and month formatting can differ for continuously published journals. Always check your specific author kit or your instructor’s brief, and treat any generator output, including ours, as a strong draft you proofread against the source itself before submitting.
IEEE citation format FAQ
Does IEEE use numbers or author names in the text?
IEEE uses numbers in square brackets, such as [1], placed in the order sources first appear. Author surnames and years never appear in the running text the way they do in APA or MLA.
Is an IEEE reference list alphabetical?
No. The reference list is numbered and ordered by first citation in the text, so the source you cite first is [1]. Alphabetizing an IEEE list is a common and marked mistake.
How many authors before using “et al.” in IEEE?
List every author up to six. When a work has more than six authors, give only the first author’s name followed by et al., with no comma before “et al.”
How do I cite a website in IEEE format?
Give the author or organization, the page title in quotes, the site name, the access date, and [Online]. Available: with the URL. You list when you accessed the page, not when it was published.
Where does the bracket number go with punctuation?
The bracket sits on the text line before the sentence’s punctuation, with a space in front, as in “the design in [2].” Do not superscript the number or place it after the period.
Do I italicize journal and book titles in IEEE?
Yes. Journal, book, and conference proceedings titles are italicized in title case, while the article, paper, or chapter title stays in quotation marks and sentence case.
Can one number cite multiple sources at once?
No single bracket holds multiple sources. Write separate brackets such as [1], [4], or use an en dash for a run like [2]–[5]. Never combine them inside one pair of brackets.
