IEEE Citation Style Guide: Format, In-Text Numbers and Examples

IEEE style is the standard citation format for engineering, computer science, and related technical disciplines. Similar to Vancouver, it uses numbered citations [1], [2], [3] but includes specific guidance for technical materials. This guide covers IEEE citation formatting. For a template and a worked example for each source type (website, journal article, book, conference paper and more), see IEEE citation format examples.

Key IEEE Characteristics

• Numbered citations [1], [2], [3] in order of appearance
• Reference list numbered sequentially (not alphabetized)
• Specific formatting for technical reports, standards, patents
• Initials appear before surnames (I. Author instead of Author I)
• Brackets around numbers: [1] not (1)
• Concise format suitable for technical writing

In-Text Citation Format

[1] First citation
[2] Second citation
[1, 2, 5] or [1]-[3] for multiple

Reference List Format (General)

[1] Initial. Surname, "Title," Publication, Volume, Pages, Abbrev. Month, Year.

Technical Materials

IEEE includes specific formats for:

• Patents: [1] I. Name, “Patent title,” Patent Number, Abbrev. Month, Date.
• Standards: [1] Standard Number, Standard Title (Publisher, Year).
• Technical Reports: [1] I. Author, “Report title,” Institution, Report Number, Month, Year.
• Software: [1] Developer, “Software Name,” Version, [Online]. Available: URL.

Differences from Other Numbered Styles

Element	IEEE	Vancouver
Author format	I. Surname	Surname I
Initials position	Before surname	After surname
Technical materials	Extensive formats	Limited coverage
Patents	Full support	Not standard
Standards	Dedicated format	Not covered

Step-by-Step IEEE Citations

1. Cite sources in order of appearance
2. Assign sequential numbers [1], [2]…
3. Create numbered reference list
4. Use IEEE format for your source type
5. Include author initials before surnames
6. Follow exact punctuation and spacing
7. Maintain appearance order (never rearrange)

Common IEEE Mistakes

1. Using surname-initial order instead of initial-surname
2. Alphabetizing reference list (violates IEEE order)
3. Missing brackets around numbers
4. Incorrect capitalization in titles
5. Missing publication details for technical sources
6. Using full month names instead of abbreviations
7. Inconsistent punctuation between entries

Citation Standards

IEEE publishes detailed style guides for different publication types. Check IEEE.org or your specific publication for version-specific requirements, as standards may vary by publication.

Verification and Tools

Use IEEE citation generators and tools to verify your formatting, especially for technical materials like patents and standards where precise formatting is critical.

Mastering IEEE Style

IEEE’s numbered system with technical material support makes it ideal for engineering and computer science research. These guidelines ensure your citations meet IEEE publishing standards.

For detailed guidance on your specific source type (journal articles, patents, standards, etc.), consult our individual guides for complete formatting examples.
