Registration Instructions

Registration Instructions

This year, we have two types of registrations(i) paper registration; and (ii) attendance registration. We have opted for this approach to, on the one hand, reflect the real cost of publishing the proceedings and, on the other hand, enable as many people as possible to attend the conference at low cost to themselves.

Fees and further information are detailed below:

Paper Registration

Paper registration $120 USD1st March 2021

Paper registration is required for full papers and extended abstracts in the main track, as well as for all contributions to the Blue Sky IdeasJAAMAS, and Demo tracks. Paper registration is not required for doctoral consortium or workshop papers.

Paper Registration Instructions. When registering your paper, you will be asked for the Paper ID and there are specific instructions for the way that the Paper ID needs to be formatted for registration purposes. For example, if you have a paper at the main conference (extended abstract or full paper), the ID you enter when registering needs to start with capital letter M followed by the submission number (e.g. M300 for paper with submission number 300). For Blue Sky Ideas papers, the ID needs to start with B followed by the number (omitting the letters “bs” and any zeros, so e.g. enter B5 for paper bs005). For JAAMAS and Demo track papers use the letters J and D respectively, followed by the submission number. These instructions are also provided on the paper registration page. Make sure you follow these precisely. Otherwise, you will get an error saying that the paper ID is not recognised. This is done to ensure that each paper has a unique ID and no paper is registered twice accidentally.

Unfortunately, the registration system does not allow the use of the same email address to register multiple papers. However, the email address for paper registration is only used for the purpose of sending a confirmation and enabling you to modify the reservation. So any other email addresses can be used when registering multiple papers.

Once you have completed the registration, you should receive a confirmation email. If you have not received it, please check your spam folder. For questions/issues, contact the local chairs.

It is important that you register your paper by 1st March 2021. Otherwise, we will not be able to include the paper in the AAMAS21 proceedings. Please contact the PC Chairs as soon as possible if you have issues with registering your paper on time.

Paper registration is for the paper only and does not include attendance registration. This needs to be done separately – see below. At least one author per paper needs to register for attendance.

Student Scholarship Winners

AAMAS 2021 runs a student scholarship scheme which provides free attendance registration for the scholarship winners. For more details, see

If you have applied for the scholarship, please wait until you receive the decision email from us before registering your attendance for the conference. However, if you are also an author and need to register your paper, please do not wait with the paper’s registration (deadline for that is 1st March 2021).

Doctorial Consortium Students

DC attendants will receive a separate email with further instructions to register for the conference. Please note that your DC paper does not have to be registered at the main conference. However, if you have an accepted paper to the main track or any of the special tracks named above (i.e., Blue Sky IdeasJAAMAS, and Demo tracks), you will need to register them by 1st March 2021.


If you are a sponsor for AAMAS 2021, please follow the instructions attached in the sponsorship email sent to you to claim your free registration.

Attending Workshops Only

While we strongly encourage workshop attendees to register for the whole conference (as the registration fees are quite low), we understand that some of you may wish to attend the workshops only. To accommodate this, the workshop-only attendance is free of charge. We are still working on the details for registering workshops only, and will publish them soon.

Registration Cancellation Policy

Paper registration: Due to the nature of the proceedings publication, we cannot refund the registration fees.

Attendance registrationThere will be no refund for the attendance registration either, due to the low attendance registration fees.
