Article Number in Journals: Meaning and Citation Guide
An article number is a unique identifier used by many scholarly journals instead of a traditional page range. It may appear as a simple number, a long numeric code, or an alphanumeric eLocator. Researchers commonly encounter it when citing papers from continuously published journals, where each article is released as soon as it is ready rather than waiting for a complete issue with sequential pagination.
The term can be confusing because a journal record may contain several identifiers at once: a volume number, issue number, article number, DOI, PubMed ID, manuscript number, and internal PDF page numbers. These elements are not interchangeable. The article number usually belongs in the position where a page range would otherwise appear. The DOI remains a separate persistent identifier at the end of the reference. The PDF may still show pages 1–12, but those pages often repeat across every article in the volume and therefore should not replace the article number in the reference list.
This distinction matters for students, PhD scholars, systematic-review authors, and researchers preparing manuscripts for publication. A reference can appear complete yet still be inaccurate if an eLocator is omitted, an issue number is mistaken for the article number, or the DOI suffix is copied into the wrong field. Reference managers do not always import these records consistently. Some place the eLocator in a page field; others use an article-number field. Manual verification is therefore essential.
Free publisher citation tools, Crossref metadata, and official style examples can resolve most straightforward cases. However, large theses and publication-stage manuscripts often contain references from journals using different conventions. In those documents, ethical academic editing services can help standardize article numbers, page ranges, DOIs, volume details, and citation punctuation without inventing missing information. Authors still remain responsible for verifying every identifier against the publisher record.
Quick Answer: What Is an Article Number?
An article number is a journal-assigned identifier that replaces the page range in a scholarly citation. It is often used in continuous article publishing and may also be called an eLocator or e-location ID.
It is not the same as a DOI. A complete reference may contain both the article number and the DOI. The article number appears with the journal’s volume and issue information, while the DOI provides a persistent online link.
When a publisher supplies an article number, use that number instead of the PDF’s internal pages in the reference entry. Follow the required citation style because styles differ in whether they add the word “Article” before the number.

Methodology and Academic Sources
This guide reflects publisher metadata practice, reference-style guidance, and academic editing workflows. Crossref guidance on article numbers and IDs explains that scholarly works may use an article number or eLocator instead of a page number. The APA journal article reference examples show how article numbers replace page ranges. Elsevier citation guidance advises including the article number where pages would otherwise appear, and Springer Nature guidance on continuous article publishing explains how the number is used with the volume.
What an Article Number Means in Scholarly Publishing
An article number is a bibliographic locator assigned to a specific scholarly article. It helps distinguish that article within a journal volume or issue when conventional page numbering is not used.
Traditional print journals often paginate an entire issue or volume sequentially. One paper might appear on pages 115–129 and the next on pages 130–144. Digital-first and continuously published journals do not need to wait for this sequence. Each completed article can be published immediately and assigned a unique locator.
The number may be short, such as 62, or long, such as 104527. Some publishers use an alphanumeric form such as e0284567. The format itself does not show quality, indexing status, or open-access status. It is simply part of the article’s publication metadata.
| Identifier | What it identifies | Typical position |
|---|---|---|
| Volume number | A major publication grouping, often corresponding to a year | After the journal title |
| Issue number | A subdivision of the volume | Usually in parentheses after the volume |
| Article number | The individual article within the journal structure | Where a page range would otherwise appear |
| DOI | A persistent digital identifier for the work | At the end of the reference |
| PDF page number | A location inside the document | Useful for reading or quotation, not as the article locator |
| Manuscript number | An internal submission or editorial tracking code | Editorial correspondence, not normally the final citation |
Article Number Versus DOI, Issue Number, and Page Range
The article number replaces the page range; it does not replace every other citation element. Understanding the distinction prevents incorrect metadata and broken references.
Article number versus DOI
The article number locates the paper within the journal’s bibliographic structure. The DOI provides a persistent online identifier. A paper can have both, and both should be included when the chosen style requires them.
Article number versus issue number
The issue number identifies the journal issue, while the article number identifies the paper. A citation may contain volume 12, issue 4, and Article 10588. Removing one because the other is present can make the reference incomplete.
Article number versus page range
They usually occupy the same citation position, but they are not formatted identically in every style. A page range might read 215–229. An article number could read Article 104527 or simply 104527.
Article number versus PDF pages
Internal PDF pagination helps readers navigate the article and may support quotation locators. It is not normally the bibliographic page range when the journal uses an article number.
Where to Find an Article Number
The publisher’s article page is the most reliable place to find the identifier. Look near the journal name, publication date, volume, issue, citation download, or recommended citation.
The number may be labelled “Article number,” “Article,” “eLocator,” “e-location ID,” or “Article ID.” In some journal designs, it appears without a label immediately after the volume and issue. The PDF header or first page may repeat it.
Crossref records and citation exports can provide an additional check. However, metadata fields vary among reference managers, so the formatted output should still be compared with the publisher record.
How to Cite an Article Number Correctly
The correct format depends on the required reference style. The underlying rule is stable: use the article number where a page range would normally appear.
APA 7th edition
APA generally uses the word Article followed by the article number. A generic pattern is:
Author, A. A. (Year). Title of article. Journal Title, volume(issue), Article 104527. https://doi.org/...
Publisher or journal style
Some numeric and scientific styles present only the number, with no “Article” label. A continuously published journal may show a citation such as Journal Name 191, 62 (2024). Follow the journal’s guide for authors rather than converting every citation to APA.
Reference-manager fields
Some software stores an eLocator in the pages field because citation styles historically expected a page element. Other systems have a dedicated article-number field. What matters is the final rendered reference, not the field label alone.
| Context | Illustrative presentation | What to check |
|---|---|---|
| APA 7 | Article 104527 | Include “Article” before the identifier |
| Publisher numeric style | 104527 | Follow the journal’s punctuation and sequence |
| Alphanumeric eLocator | e0284567 | Preserve the letter and leading zeros |
| Continuous publication | 191, 62 (2024) | Do not convert 62 into a page range |
| Reference manager | Stored in pages or article-number field | Inspect the final output carefully |
Why Researchers Search for Article Number Help
Researchers often search for this term while correcting a reference list or responding to a journal query. The source record may show no page range, and the writer must decide whether a long number belongs in the pages field, DOI field, or issue field.
PhD scholars face this problem frequently because a thesis may include older paginated articles and newer continuously published papers. First-time authors may copy PDF pages into the reference. ESL researchers may understand the source but struggle to explain or format unfamiliar metadata.
The issue becomes more serious in systematic reviews and publication manuscripts, where inaccurate identifiers can affect source retrieval and editorial checks. A well-formatted reference does not guarantee that the source is correct, but inaccurate metadata makes verification harder.
Free, Low-Cost, and Professional Options
Publisher pages, citation downloads, Crossref records, and official style examples are usually enough for individual references. Reference managers can reduce repetitive work and update citations across a large document.
However, free tools may map article numbers inconsistently. Some exports incorrectly place an eLocator in a page field, omit the identifier, or duplicate it beside the DOI. Manual inspection remains necessary.
Professional review is useful when a thesis, dissertation, or manuscript contains hundreds of references from multiple publishers. Scholarly proofreading can correct formatting inconsistencies, while manuscript assessment can identify wider publication-readiness problems.
When Self-Service Is Enough and When Expert Review Is Safer
Self-service is generally enough for a short paper with a small number of standard references. Verify each record on the publisher page, apply the required style, and check the final reference list.
Expert review becomes safer when the document mixes APA, Vancouver, Harvard, or journal-specific styles; when metadata has been imported from several databases; or when the article numbers are inconsistent across the text, tables, supplementary files, and references.
Ethical Citation and Author Responsibility
Accurate article-number formatting supports traceability, but it does not replace source verification. Authors must confirm that each identifier belongs to the cited work and that the source supports the statement being made.
Editors may correct placement, punctuation, and consistency, but they should not invent a missing number or assume that a DOI suffix is the article number. AI-generated or automatically imported references should be checked carefully against authentic publisher metadata.
Step-by-Step Article Number Verification Workflow
- Open the publisher record. Use the final article page rather than an unverified secondary citation.
- Identify the journal metadata. Record year, volume, issue, and any page range or article number.
- Look for the publisher’s recommended citation. Confirm where the number appears.
- Check the DOI separately. Do not assume the DOI suffix and article number are identical.
- Preserve the exact identifier. Keep letters, leading zeros, and hyphens.
- Apply the required citation style. Add “Article” only when the style requires it.
- Do not substitute internal PDF pages. Use them only as quotation locators where appropriate.
- Compare the reference-manager output. Correct missing or duplicated fields.
- Run a reference audit. Check that title, authors, year, journal, volume, issue, identifier, and DOI all match.
- Review journal instructions. Target-journal style takes priority for a submission.
Common Article Number Mistakes to Avoid
- Using the DOI suffix as the article number without verification.
- Replacing the article number with PDF pages 1–10.
- Confusing the issue number with the article number.
- Omitting the article number because the DOI is present.
- Adding the word “Article” in a style that does not require it.
- Removing an eLocator prefix or leading zeros.
- Treating a manuscript tracking number as final publication metadata.
- Duplicating the eLocator in both the page and article-number positions.
- Trusting a citation generator without checking the publisher page.
- Using inconsistent article-number formatting across the same reference list.
Three Practical Examples
Example 1: A PhD scholar citing a continuously published journal
Situation: The paper has volume 18, issue 2, article number 104527, and a DOI. Common mistake: The scholar enters pages 1–14 from the PDF. Correct approach: Use the article number in the reference and retain the DOI separately. Ethical expert help: A reference audit can correct the field mapping while the scholar verifies the publisher record.
Example 2: A first-time author using APA 7
Situation: The publisher citation displays an eLocator but no page range. Common mistake: The writer places the number after “pp.” Correct approach: Use “Article” followed by the identifier in the page-range position. Ethical expert help: An editor can standardize APA formatting without changing source metadata.
Example 3: An ESL researcher using multiple reference tools
Situation: One reference manager stores article numbers in the pages field and another in a dedicated locator field. Common mistake: The final bibliography contains duplicates and missing values. Correct approach: Compare rendered references with publisher citations and correct records systematically. Ethical expert help: Professional editing for researchers can improve consistency while leaving verification with the author.

Summary: Article Number
An article number is a journal-assigned locator used instead of a traditional page range. It commonly appears in continuously published journals and may be called an eLocator or e-location ID.
The article number is separate from the DOI, issue number, and PDF pages. Correct citation requires verifying the publisher record, applying the chosen reference style, and checking the final reference-manager output.
FAQs About Article Numbers
What is an article number in academic publishing?
An article number is a unique identifier assigned to a journal article, often in place of a traditional page range. It may also be called an eLocator, electronic article number, e-location ID, or article ID. Journals that publish articles continuously may release each paper online as soon as it is ready instead of waiting to assemble a paginated issue. In that model, the article number helps identify the paper within a volume, issue, or publication year. It is part of the bibliographic citation and is not usually the same as the digital object identifier. For example, a citation might show a journal title, volume 18, and article number 104527, followed by a DOI. Researchers should copy the number exactly as the publisher presents it and should not replace it with the internal PDF page numbers that often begin at page 1.
Is an article number the same as a DOI?
No. An article number and a DOI serve different purposes, although both help identify a scholarly work. An article number usually replaces the page range in the journal citation and identifies the article within the journal’s publication structure. A DOI is a persistent digital identifier registered to help readers locate the work online even if the webpage changes. A reference may therefore include both an article number and a DOI. For example, the article number may appear after the volume and issue, while the DOI appears at the end as a URL beginning with https://doi.org/. Authors should not omit the article number merely because the DOI is present, and they should not label the article number as a DOI. The safest method is to compare the citation shown on the publisher’s article page with the requirements of the chosen reference style.
Where can I find the article number of a journal paper?
The article number is usually displayed on the publisher’s landing page, in the recommended citation, near the volume and issue information, or in the PDF header. It may appear with labels such as Article, Article number, eLocator, e-location ID, or Article ID. Reference-manager exports and Crossref metadata may also contain it, although imported records should be checked against the publisher page. Do not assume that the first number visible in a PDF is the article number; it could be a manuscript number, page count, issue number, or internal production code. A reliable check is to locate the journal citation provided by the publisher and identify the element that appears where a conventional page range would normally occur. Copy punctuation, leading zeros, letters, and prefixes exactly.
How do I cite a journal article with an article number in APA 7th edition?
In APA 7th edition, when a journal article has an article number instead of a page range, write the word “Article” followed by the article number in the position where the page range would normally appear. The general sequence is author, year, article title, journal title, volume, issue when applicable, Article plus the number, and DOI. The journal title and volume are italicized, while the article number itself is not treated as a page range. Authors should use the number supplied by the journal and should not substitute the PDF’s internal pages. If the publisher uses an alphanumeric eLocator, reproduce it exactly. The DOI should still be included when available. Because journal and university requirements can vary, researchers should verify the target style guide and the publisher’s recommended citation.
Why do some journals use article numbers instead of page numbers?
Many journals use article numbers because they publish continuously. Under continuous article publishing, a paper can receive its final bibliographic details and be released immediately after production rather than waiting for a complete issue with sequential page numbering. This speeds formal publication and avoids renumbering articles as an issue grows. Each article may still have internal PDF pages starting at 1, but those pages are not unique across the volume. The article number provides a stable way to identify the paper in citations, indexing systems, and metadata. Some journals use simple numbers, while others use longer numeric or alphanumeric eLocators. The presence of an article number does not indicate article quality, open-access status, or indexing. It is primarily a publication and identification convention.
Can I use the PDF page numbers instead of the article number?
Generally, no. If the journal assigns an article number in place of a page range, that number should be used in the bibliographic reference. The PDF may contain pages numbered 1–12 for reading and quotation purposes, but those internal pages are not the journal’s article locator and may be repeated across every article in the volume. Publisher guidance commonly advises authors not to cite those internal pages as the reference page range. However, a page number may still be used as a locator for a direct quotation when the PDF has stable pagination and the citation style permits it. This means the reference-list entry uses the article number, while an in-text quotation citation may identify a specific PDF page. Always distinguish bibliographic location from quotation location.
What is the difference between an article number and an issue number?
An issue number identifies a subdivision of a journal volume, while an article number identifies an individual article. A volume often corresponds to a publication year, and the journal may divide that volume into numbered issues. The issue number usually appears in parentheses after the volume. The article number then appears where a page range would otherwise be placed. For example, a citation structure might contain volume 12, issue 3, and Article 105678. Not every journal uses issue numbers, and some continuously published journals place all articles in a single annual volume. Authors should not confuse the issue number with the article number simply because both are numeric. Publisher citation tools and the article landing page normally show their positions clearly.
Should I write “Article” before every article number?
That depends on the citation style. APA 7th edition instructs writers to include the word “Article” before an article number or eLocator when it replaces the page range. Other reference styles may present the identifier without that label, using only the number after the volume or issue. Some publishers show the number with a prefix such as e, eCollection, or Article ID, and the required format may vary. The safest approach is to follow the exact rules of the required citation style and then compare the result with the target journal’s author instructions. Do not add or remove a prefix simply to make the number look like a page range. The goal is faithful, style-compliant representation of the publisher’s identifier.
How can I check whether an article number is correct?
Verify the article number using at least two reliable points: the publisher’s article page and the recommended citation or metadata export. Crossref metadata can provide an additional check when the identifier has been deposited correctly. Confirm that the title, authors, journal, year, volume, issue, article number, and DOI all refer to the same work. Watch for confusion between an accepted-manuscript ID, PubMed ID, DOI suffix, issue number, and eLocator. Leading zeros, letters, and hyphens should be preserved. Reference managers may place the number in the pages field or article-number field depending on the software, so inspect the formatted output rather than trusting the imported record automatically.
How can Contentxprtz help with article number and citation formatting?
Contentxprtz can help researchers review journal references that use article numbers, eLocators, page ranges, DOIs, volume numbers, and issue numbers. Editorial support may include checking whether each reference follows the required style, identifying inconsistent article-number placement, standardizing punctuation, and comparing in-text citations with the reference list. Ethical editing does not invent identifiers or assume missing metadata. Authors remain responsible for verifying each article on the publisher page or another authoritative source. This support is especially useful for theses, dissertations, systematic reviews, and journal manuscripts containing references from publishers that use different continuous-publishing conventions. A citation-focused review can also be combined with academic editing or proofreading when the document needs broader language and structure improvements.
Conclusion: Use the Identifier the Journal Actually Assigned
The central challenge is not locating a number; it is identifying the correct number and placing it correctly. Researchers should use the final publisher record, distinguish the article number from the DOI and issue, and avoid substituting internal PDF pages.
Self-service tools are sufficient for many individual references. Expert-assisted editing becomes useful when a thesis, dissertation, review, or journal manuscript contains many inconsistent records. Contentxprtz helps improve clarity, citation accuracy, ethical presentation, and publication readiness while authors remain responsible for source verification.
