What is a DOI and Why Every Research Paper Needs One

You submitted your research, the journal accepted it, and now you see a string like 10.62345/IJVAST.2026.00120 next to your title. That is your DOI — and it is one of the most valuable parts of being published.

This article explains what a DOI actually is, why every serious researcher needs one, and how to use yours correctly.

What does DOI stand for?

DOI stands for Digital Object Identifier. It is a permanent, unique code assigned to a digital document — most often a research paper — that never changes, even if the journal moves, gets renamed, or shuts down.

A DOI looks like this: 10.62345/IJVAST.2026.00120

It has two parts:

• 10.62345 — the prefix, identifying the publisher (assigned by CrossRef, the global DOI registry)
• IJVAST.2026.00120 — the suffix, identifying the specific paper

You can resolve any DOI by prefixing it with https://doi.org/ — so the link https://doi.org/10.62345/IJVAST.2026.00120 will always lead to that paper, forever.

Who issues DOIs?

DOIs come from a registration agency. The most trusted one for research papers is CrossRef, used by Elsevier, Springer, IEEE, ACM, and IJVAST. Other agencies include DataCite (for datasets) and mEDRA (regional, EU).

If a journal claims to give you a DOI but the URL isn't doi.org/10.xxxx/..., it's a fake "DOI-like" identifier. Always verify by pasting the DOI into doi.org and seeing if it resolves.

Why your paper needs a real DOI

1. Permanent citability

Web URLs break. Journal websites get redesigned, papers get moved to new URLs, links die. A DOI is a contract: the publisher promises the link will always work. Citations using DOIs survive forever.

2. Google Scholar prefers DOIs

When Google Scholar's crawler finds a paper, the first thing it checks is the DOI. Papers with DOIs are indexed faster, ranked higher in search results, and credited correctly to the author. Papers without DOIs often get missed entirely.

3. Credibility for placements, grants, and admissions

Recruiters and reviewers look for the DOI on your CV. A DOI means a paper is real, peer-reviewed, and recoverable. Listing a paper without a DOI raises suspicion that it's self-published or fake.

4. Citation tracking

Tools like Scopus, Web of Science, Semantic Scholar, and Dimensions all use DOIs to track citations. Without a DOI, your paper's citation count stays at zero forever — even if 50 people cite it — because the indexing systems can't reliably link to it.

5. ORCID integration

Your ORCID profile (the researcher's LinkedIn) automatically pulls in every paper you've authored — but only if each paper has a DOI. No DOI, no auto-import.

How DOIs work behind the scenes

When a journal publishes your paper, the workflow is:

1. The publisher (IJVAST) generates the DOI suffix
2. The full DOI is registered with CrossRef along with metadata (title, authors, abstract, references)
3. CrossRef stores the mapping: DOI → URL
4. CrossRef shares the metadata with Google Scholar, Crossref Search, ORCID, OpenAlex, and other indexers

This entire process takes 24–72 hours after publication.

How to cite a paper using its DOI

Modern citation styles (IEEE, APA, MLA, Chicago) all include the DOI. Examples:

IEEE:

[1] R. Sharma, "Hybrid renewable energy systems for rural India," Int. J. Vast Adv. Sci. Tech., vol. 2, no. 1, pp. 12–18, 2026, doi: 10.62345/IJVAST.2026.00120.

APA:

Sharma, R. (2026). Hybrid renewable energy systems for rural India. International Journal of Vast Advancements in Science and Technology, 2(1), 12–18. https://doi.org/10.62345/IJVAST.2026.00120

Common DOI mistakes

• Citing the DOI as a plain URL (doi.org/10.xxx/...) without the https:// prefix
• Mixing up uppercase and lowercase — DOIs are case-insensitive, but always use the publisher's preferred casing
• Writing "DOI:" in front of the DOI in IEEE format (IEEE uses lowercase doi:)
• Adding a period at the end of the DOI in your reference (URLs in references should not have trailing punctuation)

What if my paper doesn't have a DOI?

If you published in a journal that didn't give you a DOI, your options are limited:

• Request the publisher add one (unlikely if they don't use CrossRef)
• Re-publish in a DOI-providing journal (you'd need to formally withdraw the first version)
• Deposit a preprint on Zenodo, which issues a DataCite DOI for free

Or — easier — publish your next paper in a journal like IJVAST that gives every paper a CrossRef DOI automatically as part of the standard publication.

The bottom line

Without a DOI, a paper isn't really part of the global research record. With one, your work is permanently citable, discoverable, and credited to you for the rest of your career. Before you accept any acceptance offer, confirm in writing that you'll get a CrossRef DOI.
