Fees

We have different fees for different kinds of accounts. These include annual membership fees and content registration fees for members, optional member fees for the Similarity Check service, and annual subscription fees for some metadata services.

Our Membership and Fees Committee regularly reviews our fees and makes recommendations to our Board. In July 2019 our board voted to approve our fee principles. We haven’t increased the regular annual membership or content registration fees in over 18 years.

Member fees

If you want to get a Crossref DOI prefix for your organization so you can create unique and persistent links and distribute metadata through us, you’ll need to become a member. Most members pay an annual fee at the beginning of each calendar year plus a one-time fee for each content item registered. There are also fees for the optional Similarity Check service.

Annual membership fees

If you are a member through a sponsor, your sponsor will pay membership fees on your behalf (but they may also charge you for their services - more here).

If you are eligible for the GEM programme, you will not pay annual membership fees - more here.

All other members pay an annual membership fee to Crossref. There are different membership fee tiers depending on whether you will be registering published content with us, or whether you are a funder and will be registering grants. These fees are tiered, depending on your publishing revenues or expenses, or the value of the grants that you award.

(IMPORTANT: your membership fee gives you access to our services, but DOES NOT include content registration. There are separate content registration fees payable.)

Annual membership fee tiers (for organizations registering published content)

Our membership fees for organizations who will be registering published research outputs are tiered depending on the publishing revenue or expenses of your organization. Please select your tier from the table below, and use the higher number of either:

  1. Total annual publishing revenue from all the divisions of your organization (the member is considered to be the largest legal entity) for all types of activities (advertising, sales, subscriptions, databases, article charges, membership dues, etc). Or, if no publishing revenue then:
  2. Total annual publishing operations expenses including (but not limited to) staff costs, hosting, outsourcing, consulting, typesetting, etc.

Annual membership fees (for funders who will be registering grants)

Since 2019, funders are able to register DOIs for the research grants they have awarded. Their annual membership fees are lower than for all other members, but their grant registration fees are higher. Funder fees are tiered depending on your annual award value.

Content Registration fees

Content Registration (metadata deposit) fees are one-time fees for the initial registration of content with us. There are no fees for updating the metadata for registered content. These fees are usually billed quarterly in arrears. There are different fees for different record/resource types and some fees are different depending on the date of the resource. Some record types have volume discounts available.

If you are a member through a sponsor, your sponsor will pay registration fees on your behalf (but they may also charge you for their services - more here).

If you are eligible for the GEM program, you will not pay registration fees - more here.

*Note: “Current” includes the current calendar year + the previous two calendar years, and “Backfile” is anything older than that. So for records registered with Crossref in 2024, current is anything registered with publication/award dates of 2024, 2023 or 2022. Backfile is anything registered with publication/award dates of 2021 or before.


Volume discounts: peer reviews

If you register multiple peer reviews for the same article, then volume discounts apply. The prices and discounts are different depending on whether you are the publisher of the article being reviewed. Volume discounts don’t apply across reviews for different articles.

Metadata Plus subscriber fees

If you want to get and use our metadata, you don’t need to be a member. We have a free public REST API that you can use without contacting us. Metadata Plus is a dedicated pool of servers and is a good option if you want a more predictable service level than we can support with the free API, and it comes with monthly snapshots of XML or JSON data dumps for you to do more flexible and customised analyses. There is an annual subscription fee which is payable each January or wll be pro-rated for the remainder of the calendar year.

Please select your tier from the table below, using the following criteria:

The fee tier is selected based on whichever is the higher between

  • your total annual revenue (including earned and fundraised, e.g. grants); or
  • your annual operating expenses (including staff and non-staff, e.g. occupancy, equipment, licenses etc.).

The subscriber is always considered to be the largest legal entity, unless:

  • you are a university, then the subscriber is considered to be the university department(s), school(s), or faculty(ies) that is using the service e.g. Department of Earth Sciences, School of Law, or Faculty of Medicine.
  • you are a government body, then the subscriber is considered to be the agency(ies), department(s), or ministry(ies) that is using the service, e.g. Agence de l’Innovation Industrielle, Department of Energy, or Ministry of Consumer Affairs.

If you’re an organization who works on behalf of groups of smaller organizations that want to register content with Crossref, you’ll be set up as a Sponsor. Sponsors work directly with us in order to provide administrative, technical and—if applicable—language support to the communities they work with.

The annual membership fee you pay as a Sponsor is based on the total annual publications revenue, income or funding of all the organizations you support, whichever is higher.

USD 1 million - USD 5 millionUSD 550

Each quarter you will also be sent an invoice for any content items that have been registered by the organizations that you sponsor. The charges are listed by each organization’s prefix on the invoice. There are different fees for different record types and the fees are also different depending on the publication date of the content. You will be asked to recategorize your annual fee at the end of every year, as the number of sponsoring members you represent grows.
