If you do not receive a confirmation once registration is complete, please contact J. Spargo at (800) 699-5113 or (703) 449-6418 if outside the United States or Canada. Who is a Registered ACC User? A registered ACC user can be an ACC member or nonmember who has an existing login and password. For example, ACC members and persons who have made online transactions with the College, such as purchasing products, registering for meetings, submitting an abstract or is a registered user of Cardiosource. Typically the user login and password is an email address and ACC ID number, but these can be reset by clicking on section 2 Forgot Password or by contacting the Resource Center. Who is a First-Time User? This is a new user who does not have an ACC ID number because they have not done any transactions with the College online. If you are not a registered user click on the first time user box and sign up to become a registered user.For assistance obtaining your ACC ID number, please contact the Resource Center at resource@acc.org; by telephone (800) 253-4636, ext 5603 or (202) 375-6000 ext 5603 outside of North America.
