You could get rejected for a credit card for a number of reasons – it’s a murky business as lenders are not required to tell you why they've decided to turn you down. It could be down to you having a bad credit history, or if they think you'll be risky to lend to.
Unfortunately, if you're rejected for a credit card this will usually have an impact on your credit score – especially if you make multiple applications in a short space of time. That’s why we suggest using our credit card eligibility checker to check your chances of being accepted for a wide array of credit cards, without endangering your credit score.
