After a credit card company instantly approves your application, they’ll send you a physical credit card in the mail. You might not receive your card for up to ten days. However, the company may issue you an instant use virtual credit card with your new credit card number. You can use your virtual card online and through your virtual wallet until your physical card arrives in the mail. For example, with Discover, you can start shopping and earning rewards in minutes with a virtual card before your physical card arrives in the mail, if eligible.

Pre-approval and instant approval aren’t the same thing. If you receive a pre-approved credit card offer, it means you’ve met the minimum requirements for that credit card based on a soft credit check. The lender may need additional information, like your income or monthly expenses, to make you a formal offer. So, you still typically have to complete an application to determine whether you qualify to open an account. While credit card pre-approval might mean you’re more likely to receive instant approval, it still isn’t guaranteed.
