Housing Scam Alert

The American Chemical Society does not endorse third party companies who contact our delegates and exhibitors to book accommodations through their companies for ACS Fall 2023. These third party “pirate” companies reach out to delegates and exhibitors offering special discounted hotel rooms for other associations’ meetings. Often, these discounted rooms do not exist. The primary objective of this solicitation is to obtain credit card information. ConferenceDirect, the ACS Housing Services Provider, will not contact you by phone or email requesting credit card information for reservations. ACS has no affiliation with these companies and is unable to guarantee rates and accommodations made through these companies.

Please note that ConferenceDirect is the ONLY Housing Services Provider for ACS Fall 2023. ACS does not endorse booking hotel reservations through any other sources. Please do not be misled by companies that solicit you over the phone and misrepresent themselves as the ACS Housing Services Provider. If you are contacted by one of these third party companies, please contact ConferenceDirect immediately.

All correspondence received from ConferenceDirect regarding housing for ACS Fall 2023 will include the housing services provider official logo seal.

For accurate information regarding reservations or availability, please contact our housing services provider ConferenceDirect at or the call center at (844) 293-7040 US Toll Free or (704) 837-4855 International.
