Theoretically, there’s no limit to how many credit cards you can have. So long as you have a decent credit score and can convince the provider that you can afford this new line of credit, you should experience few problems.
However, in practice, you may find that credit card providers may be wary of issuing you with a credit card if you have several already – even if these are not carrying any outstanding balances. While this might not be a ‘deal-breaker’, you should expect that they may ask a few more questions and take a bit longer to consider your application.
Also, bear in mind that applying for a new credit card will show on your credit record and may cause your credit score to temporarily drop. Therefore, it’ not wise to apply for several cards in a short amount of time.
