IUPAP supports conferences in two ways, by Sponsorship and by Endorsement. Conference organisers seeking IUPAP support of their conference in any way should refer to the IUPAP Policies for Conference Support and should submit a report on the Report Form within two months of the close of the conference.

IUPAP Sponsorship is granted to conferences in the final quarter of the year before the year of the conference, and may or may not include limited financial support of the conference. Conference organisers seeking IUPAP sponsorship of their conference should submit the Application for Conference Sponsorship in the year preceding the year of the conference, and before 1st June of that year.

IUPAP Endorsement is given to conferences at any stage before they have been held. Conferences organised by Commissions may choose to apply for endorsement in advance of their becoming sponsored conferences. Endorsement is also granted to conferences seeking IUPAP validation of their bone fides as physics conferences. Organisers seeking IUPAP Endorsement of their conference or meeting should arrange for the appropriate Commission Chair to submit the Conference Endorsement Form. If approved, endorsement will allow the use of the IUPAP Logo on all promotional material relating to the conference or meeting. At the appropriate time, endorsed conferences may apply for sponsorship.
