It’s relatively simple to apply for PayPal Credit if you’re already a PayPal user. If you don’t have a PayPal account already, then you will be prompted to create one when applying for PayPal Credit. The application is relatively simple, and will ask you to supply your date of birth, your income after taxes, and the last 4 digits of your Social Security number. However, it’s important to know that PayPal will do a hard credit pull, which might affect your credit score. Generally speaking, you should have your approval very soon after.
