Quick Answer
Zenodo issues DOIs for free with no annual fees, but the DOI resolves to a copy hosted on Zenodo's own repository rather than your journal's website, and it lacks bulk registration tools and Crossref's citation-linking network. Crossref is the industry-standard DOI registration agency for scholarly journals: its DOIs resolve directly to your website and are what most journal-quality evaluators, including UGC-CARE and Scopus, expect to see - available at low cost through a sponsor like GetDOI/SRND rather than for free.
What Is Zenodo?
Zenodo is a free, open-access repository developed by CERN. It allows researchers and publishers to assign DOIs at no cost, with no annual fees and no per-record charge. When you register a work with Zenodo, it stores a copy of that content as an open-access archive on its own platform, and the DOI resolves to that copy.
What Is Crossref?
Crossref is the official DOI registration agency built specifically for scholarly publishing - see how do I get a DOI for my journal? A Crossref DOI resolves directly to the article on your own journal's website, not to a copy on a third-party platform, and it plugs into Crossref's citation-linking network, metadata search tools, and integrations with reference managers and indexing databases.
Key Differences
| Factor | Zenodo | Crossref |
|---|---|---|
| Cost | Free, no annual fee | Paid - low-cost via a sponsor, or $275/yr direct |
| DOI resolves to | A copy hosted on Zenodo | The article on your own website |
| Bulk/automatic registration | Manual entry per record | Bulk registration for full issues |
| Citation-linking network | Not built for this | Yes - core Crossref feature |
| Industry recognition for journals | Accepted by some, but not the norm | Industry standard for scholarly journals |
| Content storage | Archives a copy on Zenodo | No separate copy - links to your site |
Does UGC-CARE or Scopus Accept Zenodo DOIs?
A DOI is not itself a UGC-CARE or Scopus indexing requirement, and some Scopus-indexed journals do use Zenodo DOIs, so having one is not automatically disqualifying. However, Crossref DOIs are the de facto standard expected by most journal-quality evaluators in scholarly publishing, and using Crossref avoids any ambiguity during review. If your journal is aiming for UGC-CARE listing or similar indexing, a Crossref DOI is the safer, more conventional choice.
Can I Switch From Zenodo to Crossref Later?
Yes. Journals that started with Zenodo DOIs (or no DOIs at all) can register Crossref DOIs for their existing back catalogue at any time - see can I register DOIs for articles I already published? Your old Zenodo DOIs, if already published and cited, remain valid and resolvable; new articles going forward would simply use the Crossref DOI instead.
Which Should My Journal Use?
- Choose Zenodo if you need a free, quick DOI for a one-off dataset, preprint, or non-journal output, and citation-linking or website resolution isn't a priority.
- Choose Crossref if you're running an ongoing scholarly journal, especially one aiming for UGC-CARE, Scopus, or similar indexing, where the industry-standard DOI and direct website resolution matter.
