Quick Answer
A Crossref DOI prefix (the part before the slash, e.g. 10.xxxxx) is assigned automatically the moment you or your sponsor set up a Crossref account for your journal - you cannot pick or buy a prefix on its own outside membership. As a direct member, Crossref allocates your prefix when your $275 annual membership is approved (2-4 weeks). Through a sponsor like GetDOI/SRND, the prefix is issued as part of sponsored onboarding, typically within 3-5 days, with prefix setup starting at ₹3,990.
A Prefix Comes With Membership, Not On Its Own
There's no separate marketplace for DOI prefixes - you can't reserve one, pay a flat fee, and receive a prefix without going through Crossref membership. The prefix is a byproduct of setting up a Crossref account, whether that account is yours directly or a sub-account under a sponsor's membership.
What a DOI Prefix Actually Is
A prefix such as 10.5555 is a unique numeric identifier Crossref assigns to your journal (or publisher). Every DOI your journal ever issues will start with that same prefix, followed by a slash and an article-specific suffix you control - e.g. 10.5555/j.jss.2026.01.002. See DOI prefix vs. DOI suffix for the full breakdown.
How to Get a Prefix: Two Paths
Path 1: Direct Crossref Membership
- Apply directly to Crossref as a member organization.
- Pay the $275/year membership fee.
- Crossref reviews your journal (ISSN, website, editorial details).
- On approval, Crossref assigns your unique prefix - typically within 2-4 weeks of applying.
Path 2: Sponsored Membership (Faster, No Annual Fee)
- Contact an authorized Crossref sponsor, such as GetDOI/SRND.
- Provide your ISSN and journal details for a requirements check.
- The sponsor sets up your journal under its Crossref membership and requests a dedicated prefix for you.
- Your prefix is typically active within 3-5 business days.
| Factor | Direct Membership | Sponsored (GetDOI/SRND) |
|---|---|---|
| Prefix setup cost | Included in $275/year | From ₹3,990 (one-time) |
| Time to receive prefix | 2-4 weeks | 3-5 days |
| Who manages the Crossref account | You | The sponsor |
| Ongoing annual fee | $275/year | ₹0 |
Prerequisites Before You Can Get a Prefix
- A valid ISSN - required in every case. See do I need an ISSN before registering DOIs?
- An active journal website with at least one published article or issue.
- Editorial and peer-review information visible on your site.
Can You Change or Move a Prefix Later?
A prefix is tied to the Crossref membership that requested it. If you start under a sponsor and later become a direct member (or switch sponsors), ask about prefix continuity before committing - reputable sponsors will clarify this upfront. This is one of the questions worth asking when choosing a Crossref sponsor.
