General Rules

Vancouver is numeric and sequential: assign a number to each source when it first appears and use that same number for all later citations of that source. Numbers may be formatted as superscripts, in parentheses, or in square brackets — check your target journal or instructor for preference.

Key formatting rules to remember:

List authors as: Surname Initials without periods (e.g., Smith AB).
Separate authors with commas; use "et al." after six authors in many variants (check specific guidelines).
Use journal title abbreviations following the NLM Catalog (Index Medicus).
Include DOI when available, formatted as doi:10.xxxx/xxxx.
Order the reference list numerically by citation order, not alphabetically.

In-Text Citations

Vancouver uses numbers to point to entries in the reference list. Cite sources as soon as you refer to the information in the text. Choose either superscript numbers or bracketed numbers depending on style guidance.

Examples:

Superscript style: Recent studies show increased incidence of X.^1,2
Bracketed style: Recent studies show increased incidence of X [1,2].

When citing multiple sources at once, separate numbers with commas or a dash for a range:

...as demonstrated in several studies [3,5-7].

Actionable rule: Assign each new source the next available number and reuse that number for subsequent citations of the same source.

Reference List

Your reference list in Vancouver style is ordered by the number assigned at first citation, not alphabetically. Start each reference with its number followed by a period and a space.

Reference list formatting example (first three entries):

1. Smith AB. Principles of Clinical Medicine. 3rd ed. London: MedPress; 2018.
2. Lee KJ, Patel M. Sleep disruption in shift workers. J Clin Sleep Med. 2019 Sep 1;15(9):1257-1264. doi:10.5664/jcsm.1234
3. World Health Organization. Hepatitis C fact sheet [Internet]. Geneva: WHO; 2021 [cited 2024 Apr 10]. Available from: https://www.who.int/news-room/fact-sheets/detail/hepatitis-c

Formatting tips:

Start each reference on a new line with the reference number followed by a period.
Do not indent wrapped lines more than one space after the number—keep consistent alignment.
Use minimal punctuation: periods after initials and end-of-reference period.

Actionable step: After writing, cross-check each in-text number with your reference list and reorder references if you add or remove citations during revisions.

Common Mistakes

Avoid these frequent Vancouver errors to keep submissions clean and publishable.

Wrong author format: Listing full first names or adding periods between initials. Correct: Smith AB, not Smith, A. B..
Alphabetical instead of numerical order: Vancouver requires references in citation order. Re-number when adding or removing citations.
Missing DOI or incorrect DOI format: Include DOI when available as doi:10.xxxx/xxxx; do not use the full DOI URL unless instructed.
Inconsistent in-text numbering style: Mixing superscript and bracketed formats confuses readers. Pick one style and apply it consistently.

Practical fix: Use Rephrasely's free Vancouver citation generator to produce consistent reference entries and then run the plagiarism checker or AI detector if required by your institution.

Frequently Asked Questions

Can I use numbers in parentheses instead of superscripts in Vancouver style?

Yes. Vancouver permits superscripts, parentheses, or square brackets for in-text citation numbers. Check your target journal or instructor for a specific preference and apply it consistently throughout the document.

How do I cite a source with more than six authors?

Many Vancouver variants list the first six authors followed by "et al." (e.g., Smith AB, Jones CD, Lee EF, et al.). Verify the required author-count cutoff with the publication you are submitting to and use Rephrasely's citation generator to automate this truncation.

Does Vancouver require journal name abbreviations?

Yes, Vancouver normally uses NLM (Index Medicus) abbreviations for journal titles. If you're unsure of the correct abbreviation, consult the NLM Catalog or let Rephrasely generate the citation — it includes standard journal abbreviations when available.
