Online account registration

1. How do I set up my CarMax Auto Finance account on-line?

You’ll first need to set-up a MyCarMax login. NOTE: this will include an email verification step.

Once you have a MyCarMax login or if you already have one, simply click on the “set up new account” after you logged onto MyCarMax.

At this point, you’ll need to have your CarMax Auto Finance account number, the last 4-digits of your social security number, and your date of birth available. Enter these details, agree to the E-Sign Consent and the Online Account Services Agreements, and you’ll have access to your account.

2. I’m having difficulty registering. What else can I try?

There may be a couple of reasons why you are having difficulty. Please ensure you are using a valid email address and that the last 4 digits of your social security number and date of birth match the information provided at the time of purchase. Also, if the email address you entered is already in use and associated with another MyCarMax account, you’ll need to select a different email address.

3. What if I don’t get my validation code in my email?

First, confirm that it’s not in your junk/spam folders. If it’s not there, contact Customer Service at 800-925-3612 for assistance.

4. How do I obtain my CarMax Auto Finance account number?

The account number is listed in the welcome email or the welcome letter you received. If you cannot easily access your account number, please contact customer service for assistance at 800-925-3612.

5. I’m a co-buyer on the account; can I have access to my account online?

Yes, both a primary applicant and a co-buyer will have the ability to establish their own individual access to the CarMax Auto Finance account. As a co-buyer, set up your own MyCarMax account, then, simply enter the account number, the last 4-digits of your social security number, your date of birth and agree to the E-Sign Consent and Online Account Services Agreements to create your own association to the account.

6. I’m an existing CarMax Auto Finance customer and have an online account. I just financed a new vehicle through CarMax Auto Finance. How do I add this to my online account?

As long as the last 4-digits of your social security number and your date of birth match the existing account, you’ll automatically access the new account. The new account will appear on your overview page when you log onto your CarMax Auto Finance account. If you are unable to access the new account, please contact customer service for assistance at 800-925-3612.
