IEEE Citation Style: Quick Guide for Engineers

IEEE (Institute of Electrical and Electronics Engineers) style uses numbered references in square brackets. It’s the standard for engineering, computer science, and electronics publications. If you’re submitting to an IEEE journal or conference, or studying in these fields, this is your style. The IEEE Editorial Style Manual documents the full numbering and abbreviation conventions directly, if you need the source rules for an edge case this guide doesn’t cover.

How IEEE Numbering Works

Unlike APA or MLA, IEEE doesn’t use author names in the text. Instead:

• Each source gets a number in the order it first appears
• In-text citations use square brackets: 1, 2, 3
• The reference list is ordered by number, not alphabetically

In-Text Examples

Single source:

As shown in 1, neural networks can...

Multiple sources:

Several studies 1, 3, 5 have demonstrated...

Range of sources:

Previous work 1–4 established...

Reference List Format

Journal Article

1 J. D. Smith and M. K. Johnson, “The impact of citation accuracy on academic publishing,” J. Academic Writing, vol. 15, no. 3, pp. 45–62, Mar. 2025, doi: 10.1234/example.

Key formatting rules:

• Author initials before last name (J. D. Smith, not Smith, J. D.)
• Article title in quotation marks, sentence case
• Journal name abbreviated and italicized
• Volume, number, pages, month, year in that order
• DOI at the end with “doi:” prefix

Conference Paper

2 A. Brown, “Machine learning for citation analysis,” in Proc. Int. Conf. Academic Technology (ICAT), New York, NY, USA, Jun. 2025, pp. 234–241.

Key differences from journal articles:

• “in” before the conference proceedings title
• Conference proceedings abbreviated with “Proc.”
• Location and date of conference included

Technical Standard

6 IEEE Standard for Software Quality Assurance Processes, IEEE Std 730-2014, 2014.

Preprint

7 F. Chidziva, “Anomalous thermal transport in layered antiferromagnets,” arXiv, 2025. [Preprint]. Available: https://doi.org/10.48550/arXiv.2503.04521

Key points:

• [Preprint] descriptor after the year, before the availability line
• No page numbers – a preprint hasn’t gone through the pagination a published journal issue adds

Dataset or Software

8 K. Boateng, “Urban heat island temperature readings for Accra, 2015-2024,” version 2, Zenodo, 2024. [Dataset]. Available: https://doi.org/10.5281/zenodo.1234567

Key points:

• [Dataset] (or [Computer software] for code) descriptor placed after the year
• Version number included immediately after the title
• “Available:” replaces “doi:” when the link points to a repository landing page rather than a resolvable DOI

Thesis or Dissertation

9 R. Wilson, “Citation practices in engineering education,” Ph.D. dissertation, Dept. Educ., Stanford Univ., Stanford, CA, USA, 2024.

Key points:

• Degree type stated directly (“Ph.D. dissertation,” “M.S. thesis”)
• Department, university, city, and country included, matching the conference paper format above

Author Name Formatting

IEEE uses a distinctive format for author names:

• First author: J. D. Smith (initials first, then last name)
• Two authors: J. D. Smith and M. K. Johnson
• Three or more: J. D. Smith, M. K. Johnson, and A. Brown
• Six or more: J. D. Smith et al.

Journal Name Abbreviations

IEEE abbreviates journal names following the ISO 4 standard. Common abbreviations:

• IEEE Transactions on becomes IEEE Trans.
• Journal of becomes J.
• International becomes Int.
• Conference becomes Conf.
• Proceedings becomes Proc.

Month Abbreviations

IEEE uses three-letter month abbreviations: Jan., Feb., Mar., Apr., May, Jun., Jul., Aug., Sep., Oct., Nov., Dec.

Troubleshooting: Renumbering When You Add or Remove a Source

Because IEEE numbers sources by order of first appearance, inserting a new citation early in your paper shifts every number after it – source 4 can become 5 the moment you add a reference earlier in the introduction. This is the single most error-prone part of writing in IEEE style by hand: a reference list built incrementally almost always ends up with at least one mismatched number by the final draft. Two ways to avoid it: finish citing before you build the numbered reference list, or use a reference manager that renumbers automatically whenever a citation moves. If you’re managing a longer source list in LaTeX, our guide to exporting citations to BibTeX covers how LaTeX’s own bibliography tools handle renumbering for you rather than tracking it by hand.

Worked Example: Building a Short Reference List

Suppose your introduction cites three sources in this order: a journal article on citation accuracy, a conference paper on machine learning, and a technical standard. Numbered by first appearance, your reference list looks like this:

1 J. D. Smith and M. K. Johnson, “The impact of citation accuracy on academic publishing,” J. Academic Writing, vol. 15, no. 3, pp. 45–62, Mar. 2025, doi: 10.1234/example.

2 A. Brown, “Machine learning for citation analysis,” in Proc. Int. Conf. Academic Technology (ICAT), New York, NY, USA, Jun. 2025, pp. 234–241.

3 IEEE Standard for Software Quality Assurance Processes, IEEE Std 730-2014, 2014.

If a later revision moves the Brown citation out of the introduction and it now first appears in your conclusion instead, 2 doesn’t stay put – it gets renumbered based on wherever it now first appears, and every source between its old and new position shifts by one. This is why experienced IEEE authors build the numbered reference list only after the argument itself is stable, not while still revising the draft.

Common Mistakes

1. Alphabetizing the reference list – IEEE orders by first appearance, not alphabetically
2. Using author-date format – IEEE uses numbers only, never (Smith, 2025)
3. Full journal names – IEEE always abbreviates journal titles
4. Missing “doi:” prefix – IEEE uses “doi:” not “https://doi.org/”
5. Wrong author name order – Initials come first in IEEE (J. D. Smith), not last (Smith, J. D.)
6. Forgetting to renumber after editing – moving or deleting a citation shifts every number after it; check every in-text bracket against the final reference list before submitting
