FREQUENTLY ASKED QUESTIONS

 

WHAT IS REQUIRED TO HAVE AN AFFIRM ACCOUNT?

  2. Provide a valid U.S. or APO/FPO/DPO home address. Buy with Affirm is not currently available to West Virginia residents.
  3. Provide a valid U.S. mobile or VoIP number and agree to receive SMS texts. The phone account must be registered in your name.
  4. Provide your full name, email address, date of birth, and the last 4 digits of your social security number to help us verify your identity.



DO I HAVE A CREDIT LIMIT WITH AFFIRM?


Unlike a credit card, Affirm is not a revolving line of credit. While customers can take out multiple Affirm loans at once, each Affirm loan application is evaluated separately as a closed-end transaction. An application from a returning customer may be denied, however, if that customer has failed to repay other Affirm loans on time or if the customer shows excessive borrowing behavior.

HOW DO I PAY MY BILLS?


You can pay your Affirm bills online at www.affirm.com/pay. They accept payment by debit card, bank transfer and check.

DOES AFFIRM PERFORM A CREDIT CHECK?


Yes, when you first create an Affirm account, Affirm perform a ‘soft’ credit check to help verify your identity and determine your eligibility for financing. This ‘soft’ credit check will not affect your credit score.

WHY WAS I PROMPTED TO PAY A DOWN PAYMENT WITH A DEBIT CARD?


Affirms tries hard to approve every purchase but sometimes can’t approve the full amount. When this happens, Affirm provides a debit card down payment option so that you may still complete your purchase right away.

WHY WAS I PROMPTED FOR A CHECKING ACCOUNT?


Affirm sometimes requires additional information to consider a credit application. Such information may include an active checking account, which helps Affirm verify your identity and your ability to repay the requested loan. If they prompt you for this information but you are unable to provide it, Affirm will be unable to approve your credit application.
