Registration fees

To encourage the most inclusive participation in the conference, the IAS has adjusted the registration fees to make the conference as accessible as possible.

The conference has a four-tiered fee structure, offering lower registration fees for delegates from upper-middle-income countries, lower-middle-income countries and low-income countries (based on the World Bank Classification), as well as for students/postdocs/young persons.

To participate in IAS 2025, delegates and students/postdocs/young persons can choose between two registration formats.

You are entitled to put USD 75 of your registration fee towards a two-year IAS membership, which will be activated following the conference. If you are already an IAS Member, your existing membership will be extended by two years. For more information, take a look at the IAS membership benefits.

In-person plus virtual

Virtual

To attend IAS 2025 on their own, delegates must be at least 18 years old.

To attend the in-person conference, individuals under the age of 18 (as of 13 July 2025) must be registered as accompanying persons under the age of 18. The parent/guardian must submit and provide a copy of the completed parent/guardian consent form.

An accompanying person under the age of 18 must be with the registered regular delegate at all times when they are in the conference venue. The regular delegate they are accompanying will be held responsible for all actions of the accompanying person under the age of 18.

In addition, accompanying persons under the age of 18 may be asked to provide official photo identification (for example, passport or student ID) confirming their age.

This registration fee for an accompanying person under the age of 18 includes in-person access to all conference sessions, satellite sessions, pre-conferences, the poster exhibition and the exhibition.

You can register up to two accompanying persons under the age of 18.
