Vancouver is the numbered referencing style used across medicine, nursing and many science courses in the UK. Instead of author-date citations, it numbers sources in the order they appear and lists them by number at the end. This complete guide explains how Vancouver works, how to cite in the text, how to format a reference list, common source types, and how it differs from Harvard and APA.
What Is Vancouver Referencing?
Vancouver is a numeric referencing system. Each source is given a number the first time it is cited, and that number is reused every time the source appears again. The reference list at the end is ordered by number, not alphabetically.
In-Text Citations
Cite sources with a number in brackets or superscript at the point of use — for example “recent trials [3] show…”. The same source keeps the same number throughout. You can cite several at once, such as [2,4,5] or a range [6–8].
Formatting the Reference List
List references in the order they were first cited, each numbered to match. A typical journal reference gives: author(s), article title, abbreviated journal name, year, volume(issue), and page range. Follow your institution's exact punctuation, as Vancouver has small variations.
Common Source Types
✓ Journal article — authors, title, journal, year, volume(issue):pages.
✓ Book — authors, title, edition, place, publisher, year.
✓ Website — author/organisation, title, year, URL and date accessed.
✓ Online report or guideline — organisation, title, year, URL.
Vancouver vs Harvard and APA
The key difference is the citation form. Harvard and APA are author-date styles with alphabetical reference lists. Vancouver is numeric with a citation-order list. Medicine and nursing usually prefer Vancouver; social sciences often prefer Harvard or APA. See our Harvard guide and APA 7 guide.
Common Mistakes to Avoid
✓ Listing references alphabetically instead of by citation order.
✓ Giving a source a new number each time it appears.
✓ Inconsistent punctuation or journal abbreviations.
✓ Missing page numbers or access dates.
✓ Mixing Vancouver with author-date citations.
Tips for Accurate Vancouver
Number sources as you cite them, reuse numbers consistently, keep the reference list in citation order, and check your university's exact Vancouver variant — a reference manager can automate much of this.
