Learning how to reference in vancouver style is an essential skill for UK university students. 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.
How to reference in vancouver style: Step-by-Step Guide
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.

Where Vancouver Referencing Is Used in UK Healthcare Education
Vancouver referencing (also known as the Vancouver system or ICMJE style, after the International Committee of Medical Journal Editors) is the standard citation style in medicine, dentistry, pharmacy, nursing (in some programmes) and biomedical sciences. It uses a numbered citation system similar to IEEE but formatted specifically for biomedical literature.
UK students in medical, dental, pharmacy and biomedical science programmes will typically encounter Vancouver in their clinical or research modules. Some nursing programmes use Vancouver; others use Harvard or APA. The BMJ (British Medical Journal), The Lancet, JAMA and most other major medical journals use Vancouver-compliant formatting.
Understanding Vancouver referencing is therefore a professional competency as well as an academic requirement — medical researchers, clinicians writing case reports, and healthcare professionals contributing to systematic reviews or clinical guidelines will all need to use Vancouver formatting in their professional careers.
Vancouver In-Text Citations: The Numbered System
Vancouver uses superscript numbers or numbers in parentheses for in-text citations. Sources are numbered sequentially in the order they first appear in the text, and the same number is used every time that source is cited subsequently.
Superscript format (most common in journals): The results confirmed the hypothesis.⁶ Multiple citations: ⁶⁻⁹ or ⁶,⁸,¹¹
Parenthetical format (used in some programmes): The results confirmed the hypothesis. (6) Multiple citations: (6-9) or (6,8,11)
Check which format your institution or module requires. Some UK universities specify parenthetical format for student work because superscript is harder to format consistently in word processors.
In-text citations in Vancouver are placed after the cited information, at the end of the relevant sentence, before the final punctuation. If citing multiple sources, use en-dashes for consecutive numbers (6–9) and commas for non-consecutive numbers (6,8,11).
Formatting the Vancouver Reference List
The Vancouver reference list appears at the end of the paper, titled “References” (not “Bibliography”). Entries are listed numerically in the order they first appear in the text — not alphabetically. This is the same convention as IEEE but with different entry formatting.
The standard Vancouver format for the most common source types follows ICMJE recommendations:
Journal article:
Surname AB, Surname CD. Title of article. Abbreviated Journal Title. Year;Volume(Issue):Pages. doi:DOI.
Example: Smith AB, Jones CD, Williams EF. A randomised trial of X in patients with Y. BMJ. 2022;378:o1234. doi:10.1136/bmj.o1234.
Book:
Surname AB. Title of book. Edition. City: Publisher; Year.
Example: Kumar P, Clark M. Kumar and Clark’s Clinical Medicine. 10th ed. Amsterdam: Elsevier; 2020.
Book chapter in an edited work:
Surname AB. Title of chapter. In: Editor AB, Editor CD, editors. Title of book. City: Publisher; Year. p. First–last page.
Website:
Organisation/Author. Title of page [Internet]. Publisher; Year [cited Year Month Day]. Available from: URL
Example: NHS England. NHS long-term plan [Internet]. NHS England; 2019 [cited 2024 Jan 15]. Available from: https://www.longtermplan.nhs.uk
Author Names in Vancouver References
In Vancouver referencing, author names in the reference list follow a specific format: Surname followed by initials (no periods after initials). For example: Smith AB, Jones CD.
When an article has six or fewer authors, list all of them. When an article has seven or more authors, list the first six followed by “et al.”: Smith AB, Jones CD, Williams EF, Brown GH, Davis IJ, Taylor KL, et al.
If a work has no individual author, the organisation name is listed as the author. If a work has no author at all, begin the reference with the title.
Vancouver Reference List Formatting Conventions
Several specific formatting conventions apply to the Vancouver reference list.
Journal title abbreviations — Journal titles in Vancouver references are typically abbreviated using standard PubMed/Index Medicus abbreviations. The Lancet is “Lancet,” the British Medical Journal is “BMJ,” the New England Journal of Medicine is “N Engl J Med.” A searchable list of journal abbreviations is available through PubMed’s NLM Catalog.
DOIs and URLs — Include DOIs for journal articles where available, formatted as “doi:10.xxxx/xxxxxx” at the end of the entry. For websites and online reports, include the full URL and the date accessed.
No hanging indent — Unlike Harvard referencing, Vancouver reference lists do not use a hanging indent. Entries are formatted with a standard first-line indent or no indent, with the reference number preceding each entry.
Frequently Asked Questions
What is Vancouver referencing?
A numeric referencing style that numbers sources in the order they are cited and lists them by number.
Who uses Vancouver style?
It is common in medicine, nursing and many science disciplines.
How do in-text citations work in Vancouver?
You place a number in brackets or superscript at the point of citation, reusing the same number for each source.
How is the reference list ordered?
By the order in which sources were first cited, not alphabetically.
What is the difference between Vancouver and Harvard?
Vancouver is numeric with a citation-order list; Harvard is author-date with an alphabetical list.
Can I cite multiple sources at once?
Yes — for example [2,4,5] or a range such as [6–8].
Do I reuse the same number for a repeated source?
Yes — each source keeps its original number throughout.
What goes in a Vancouver journal reference?
Authors, article title, abbreviated journal name, year, volume(issue) and page range.
Should I use a reference manager?
It helps — tools can format and renumber Vancouver references automatically.
Is there one fixed Vancouver format?
There are minor variations; always follow your institution's specific guidance.
Why does medicine use Vancouver rather than Harvard referencing?
Vancouver was developed specifically for biomedical literature by the ICMJE to standardise citation across medical journals. Its numbered system is compact and less disruptive to clinical or scientific text than author-date systems, making it particularly well-suited to papers with many citations in close proximity. Most major medical journals worldwide use Vancouver-compliant formatting.
What is the difference between Vancouver and IEEE referencing?
Both use numbered in-text citations and list references numerically. They differ in the specific formatting conventions for reference entries: author name format, journal title abbreviation standards (PubMed for Vancouver vs IEEE/ISO for IEEE), and the types of sources most commonly cited differ between biomedical (Vancouver) and engineering/computing (IEEE) contexts.
Do I always need to include a DOI in Vancouver references?
Yes — where a DOI is available, it should be included. DOIs provide permanent, reliable links to published articles and are the preferred location identifier in current ICMJE guidelines. If no DOI is available, include the full URL for online sources.
How do I abbreviate journal titles for Vancouver references?
Use the standardised abbreviations from the National Library of Medicine (NLM) Catalog or the PubMed journal list. The NLM Catalog is freely searchable at https://www.ncbi.nlm.nih.gov/nlmcatalog. If a journal is not in NLM, use the ISSN Portal or spell the title in full.
Can I use reference management software for Vancouver formatting?
Yes — reference management tools such as Zotero, Mendeley, RefWorks and EndNote all support Vancouver and ICMJE citation styles. Using reference management software significantly reduces formatting errors and saves time, particularly for longer papers with many references. Most UK universities provide free access to at least one reference management tool through their library.
