There is no hard inquiry to your credit report to check if you’re pre-approved. If you’re pre-approved, and you move forward with submitting an application for the credit card, it will result in a hard inquiry which may impact your credit score. Receiving a pre-approval offer does not guarantee approval, and any pre-approved offers you receive may have offer terms (including, but not limited to, APR rates) that vary from other offers you see elsewhere on discover.com. Some card products are not eligible for pre-approval.
