At this stage in the process, you have not applied for credit and you have not been approved or denied for any credit card product. If you wish to apply for a credit card with any participating issuer, you will need to click through to complete and submit an application directly with that issuer. CreditCards.com will not be able to tell you why you did or did not appear to be a match with any particular credit card product.
If you click through to apply for some of the credit card products shown, some issuers will know that you have come through the filtering process and that you meet certain criteria established by the issuer. If you do not click through and apply, the issuer will not know this information about you.
