If you are using an individually purchased account, including individual accounts purchased on your behalf by your school, your username is the email you entered when you signed up. If you have multiple email addresses, make sure you are using the one you entered at signup. If you still can't sign in, it's possible there was a typo in your email address when you signed up. Please email us at BBCustomerService@mheducation.com for assistance.
If you set up your account under your school's Institutional Subscription, your username is a name you entered at signup that includes letters and at least one number, NOT an email address. If you cannot remember the username you entered, it is included in the welcome email you received after setting up your account.
If you still need assistance, you can contact us at BBCustomerService@mheducation.com
