Free DOI Options for Journals and Authors
The genuinely free routes to a DOI, what each is good for, and the catches.
No DOI registration agency is free for a journal by default: Crossref and DataCite both charge members. But there are genuinely free routes. Which one fits depends on whether you’re an author with one paper or a journal with every issue to register.
The free routes
| Route | Who it suits | The catch |
|---|---|---|
| Zenodo | Authors, preprints, datasets, posters | The DOI leads to Zenodo, not your journal, and uses Zenodo’s prefix |
| Figshare, OSF and similar repositories | Authors and research data | Same as Zenodo; check each site’s limits |
| Your university’s repository | Staff and students of that university | Only for the university’s own output; ask your library |
| Crossref GEM | Journals based in eligible countries | Only if both your mailing and billing addresses are in an eligible country |
For journals: the honest picture
If your journal is in a GEM-eligible country, Crossref membership and registration are fee-free, and that’s the best option there is. Otherwise, journal DOIs cost money, but the cost is modest for a small journal: a yearly fee in the lowest tier plus a small amount per article. See how to get DOIs through Crossref.
Using free repository DOIs for every article is possible, but each one points to the repository, not your website, and you lose citation tracking and reference linking. It suits a stop-gap better than a long-term plan.
Be careful with services that offer journals “free DOIs” in exchange for listing or fees elsewhere. A real DOI resolves at https://doi.org/ and can be looked up on the registration agency’s own search. If it doesn’t, it isn’t a DOI.
For authors
If your article is published in a journal that registers DOIs, it already has one: don’t create a second. Use Zenodo or another repository for things the journal doesn’t cover, such as your preprint, data or slides.

Questions
Is there any completely free DOI agency for journals?
Not by default. Crossref waives its fees for publishers in GEM-eligible countries; elsewhere, journals pay a yearly fee and a small fee per DOI.
Are Zenodo DOIs real DOIs?
Yes. They’re registered with DataCite and resolve through doi.org like any other DOI.
How can I check if a DOI is genuine?
Open https://doi.org/ followed by the DOI. A real DOI resolves; you can also look it up on Crossref Search or DataCite Commons.
