Do I need a mobile number to use Affirm?

Yes, you’ll need a mobile phone number from the U.S. or U.S. territories. This
helps Affirm verify it’s really you who is creating your account and signing in.

How do I make my payments?

You can make or schedule payments at affirm.com or in the Affirm app for iOS
or Android. Affirm will send you email and text reminders before payments are
due.
