What Information Does Affirm Need?
To help confirm your identity they need name, email, mobile phone number, birthday, and the last 4 digits of your SSN.

Does Affirm Perform a Credit Check?
When you first create an Affirm account, Affirm performs 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. Affirm may run additional 'soft' credit checks on future purchases.

Why was I prompted to pay a down payment with a debit card?
Affirm tries hard to approve every purchase but sometimes cannot approve the full amount. In these cases, there is the option to put a down payment with a debit card so that you are still able to complete the purchase.

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 Affirm prompts you for this information but you are unable to provide it, Affirm will be unable to approve your credit application.

Linking your checking account DOES NOT authorize Affirm to debit your account. It only allows them to determine your ability to pay.
