Importance of Staying in an Official JMM Hotel

The importance of reserving a room at one of the official JMM hotels cannot be stressed enough. The AMS makes every effort to keep participants’ expenses at the meeting as low as possible and a lot of work and effort goes into negotiating the most affordable hotel rates. When a participant registers for the meeting and reserves a room at an official JMM hotel, they are helping to support not only JMM 2023, but future JMMs as well.

Reserving a Room

Participants are encouraged to register for the JMM in order to reserve hotel rooms at the JMM rates. If a participant needs to reserve a hotel room before they are registered for the JMM, they should contact the Mathematics Meetings Services Bureau (MMSB) at or 1-800-321-4267 (ext. 4094 or ext. 4144) for further instructions.

Special rates have been negotiated exclusively for this meeting at the following hotels: Marriott Copley, Sheraton Boston, and Westin Copley Place. See details on these hotels here.

A link to the JMM 2023 hotel reservation portal will be included in the confirmations of registrations sent by email. If a participant needs the link sent directly to them, they should send a request to If any participant has difficulty reserving a hotel room, they should send email to for assistance. We strongly prefer that you register for the meeting before you reserve a hotel room; however, if that is not possible and you want to confirm your accommodations before registering, send email to for a direct link to the hotel portal.

Anyone who needs to reserve a hotel room and does not have a credit card to guarantee it should send email to for further instructions. If a check is being used to guarantee a room, the reservation and check must be received by the MMSB no later than November 30, 2022.

BEWARE of Room Poachers and Housing Scams

Please beware of aggressive housing bureaus and marketing groups that target potential attendees and exhibitors of a meeting. They are sometimes called "room poachers" or "room-block pirates" and these companies often position themselves as the meeting’s housing bureau or a marketing group working on behalf of the meeting. They try to convince attendees and exhibitors to unknowingly book outside the official room block. They call or email people who they think will more likely than not attend the meeting and lure them with room rates that are significantly less than the published group rate -- for a limited time only. And people who find this offer tempting may hand over their credit card data, believing they have scored a great rate and their housing for the meeting is confirmed. Unfortunately, it is not and this often turns out to be the start of a long, costly nightmare for them.

These groups are not affiliated with the Joint Mathematics Meetings in any way. The only official housing bureau for this meeting is the MMSB and they would never call or email anyone to solicit reservations. The only way to book a room at a negotiated JMM rate is through the JMM registration form or through the MMSB. 

The JMM cannot be held responsible for any damages incurred as a result of hotel bookings made with unofficial housing bureaus and marketing groups.
