The Vancouver referencing style is one of the most widely used citation formats in scientific, medical, and academic writing. If you're working on a research paper, thesis, or publication in healthcare or life sciences, understanding this format is essential for credibility and academic integrity.
Unlike author-date systems such as APA or Harvard, the Vancouver style uses numbered citations within the text that correspond to a reference list. This makes it especially efficient for dense scientific writing where clarity and brevity are crucial.
In this comprehensive guide, you will learn everything you need to know about Vancouver referencing—from basic rules and formatting to advanced examples and common mistakes. Whether you're a beginner or looking to refine your skills, this article will help you master the format and avoid costly errors.

The Vancouver referencing style was developed by the International Committee of Medical Journal Editors (ICMJE). It is widely used in medicine, biology, and other scientific disciplines due to its structured and concise approach.
In this system, sources are cited using numbers in the text, either in parentheses or superscript. These numbers correspond to a numbered list of references at the end of the document.
| Feature | Vancouver Style | APA Style |
|---|---|---|
| In-text citation | Numbers (e.g., [1]) | Author-date |
| Reference order | By appearance | Alphabetical |
| Common use | Medical, scientific | Social sciences |
