With most credit card issuers, you can apply for a new card online, over the phone or via mail. Approval is typically the quickest for online applications, whereas applying via mail tends to take the longest.
Some issuers provide instant approval of credit cards. And you may even be able to start using your new card immediately. However, receiving your physical card via mail may take up to 10 business days.
Having all the required information at hand when applying for a new card will ensure you can complete the process quickly and accurately. Even if you are pre-approved or pre-qualified for the card, you will still need to submit a formal application if you decide to move forward.
