When trying to log in on the AAA Mobile App, please try the following steps:

After confirming their zip code, you will be routed to a screen that welcomes them to AAA.com.
On this screen, there are two buttons – “PLEASE LOGIN” and “REGISTER.”
 
If you already have an active AAA.com account (on the website), please select “PLEASE LOGIN.” On the next screen, you may enter your AAA.com username and password (email address and password), which will grant you access to your AAA Mobile account and other features, including the ability to request roadside assistance.
 
If you have never set up a AAA.com account, please select “REGISTER.” The following screens will ask you to provide information including your Membership number and zip code so a AAA.com account may be created on your behalf. Once the AAA.com account is setup, it will work for both the AAA Mobile app and AAA.com. Should you receive a message that says your email address is already in use, this indicates you already have a AAA.com account created. Please select the back button until you are able to select the “PLEASE LOGIN” button, and use your email address and password for AAA.com to login.
Should you not remember your password, please use the prompts to reset your account password.
