Fees

We have different fees for different kinds of community participation. These include annual membership fees and content registration fees for members, optional member fees for Similarity Check, and annual subscription fees for Metadata Plus.

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 since 2004 years but please note that fees may be changed soon as part of the Resourcing Crossref for Future Sustainability (RCFS) Program that started in 2024.

Member fees

If you want to get a Crossref DOI prefix for your organisation 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 (whichever is higher), 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 organisations registering published content)

Our membership fees for organisations who will be registering published research outputs are tiered depending on the publishing revenue or expenses of your organisation, whichever is higher. 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 organisation (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.

> 500 million USD50,000 USD

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.

Total annual award value (USD)Annual membership fee
< 500k USD200 USD

2.1-10 million USD600 USD

> 1 billion USD1,200 USD

Content Registration fees

Content Registration (metadata deposit) fees are one-time fees for the initial registration of DOI metadata records with us, and they are usually billed quarterly in arrears. 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.

There are different fees for different record types, and some record types have discounts for older content - newer items are charged at the “current record” price, and older items are charged at the “back-year record” price. Some record types also have volume discounts available.

After the initial registration fee, there are no further fees for updating the metadata associated with existing records.

*Note: “Current record” prices are for content that was published (or awarded, in the case of grants) in the current calendar year + the previous two calendar years, and “Back-year record” prices are for content that is older than that. So for records registered with Crossref in 2025, current records are anything registered with publication/award dates of 2025, 2024, and 2023. Back-year is anything registered with publication/award dates of 2022 or before.


Pricing for peer reviews

If you register more than one peer review for the same article, then you pay a cheaper price than the first peer review. The prices are also different depending on whether you are the publisher of the article being reviewed or not.

Similarity Check fees

Members are able to participate in Similarity Check. As a participant, you pay an annual service fee to use Similarity Check plus a per document charge each time you check a document. Even members who are part of the GEM Program will pay these fees.

Similarity Check annual service fee

Members of Crossref can participate in Similarity Check. The service fee is 20% of your annual membership fee and is included in your annual membership fee invoice.

Metadata Plus subscriber fees

If you want to get and use our metadata, you don’t need to be a member and you don’t have to pay a fee. We have a free public REST API that you can use without contacting us.

However, if you want a more predictable service level than we can support with the free API, then our optional paid-for service Metadata Plus could work for you. The service has a dedicated pool of servers and comes with monthly snapshot data dumps of XML or JSON for you to do more flexible and customised analyses. There is an annual subscription fee which pro-rated in your first year, and then renews each January. This annual fee is tiered, based on whichever is the higher between the subscriber organisation’s:

  • total annual revenue (including earned and fundraised, e.g. grants); or
  • 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.

Some organizations work with us as a Sponsor to facilitate Crossref membership for groups of smaller organisations.

Sponsors provide administrative, technical and—if applicable—language support to the communities they work with. Sponsors pay one membership fee to Crossref for all the members that they work with, and sponsors also pay the content registration fees for any content registered by their members. Many sponsors then pass on these fees to members and/or charge the members for their services.

Sponsors may only work with member organizations whose annual publishing revenue or expenses (whichever is higher) is under 1 million USD.

The annual membership fee you pay as a Sponsor is based on the total combined annual publication revenue or expenses (whichever is higher) of all the members you sponsor.

Total combined publishing revenue or expensesAnnual fee
< 1000 USD200 USD
1000 USD - 1 million USD275 USD

100 million - 200 million USD22,000 USD
200 million - 500 million USD33,000 USD
> 500 million USD50,000 USD

We’ll ask you to re-categorise your annual membership fee at the end of every year, as the number of members that you support grows, and the combined publishing revenue or expenses of these members also grows.

If you sponsor grant-awarding funders, there are a different set of membership fees.

At the end of each quarter you’ll be sent an invoice for any content items that have been registered by the members that you sponsor during that quarter. The charges are listed by each member’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.

Similarity Check fees

If you decide to offer the optional Similarity Check service to the members you sponsor, you will pay an annual Similarity Check service fee on behalf of the members that you sponsor (which is 20% of your annual membership fee), and you will also pay the per document checking fees for your members who make use of the service. This will be itemised by member iThenticate account number on your invoice.
