Many credit card issuers offer online applications and instant approval. If you don't get instant approval or your credit card issuer doesn't offer instant approval, you can check the status of your application online. The exact method for checking your credit card status online varies depending on the issuer, but most follow a similar process.
To check your credit card status online, visit the card issuer's website and look for a link that says "check my status" or something similar. Fill in the information the issuer wants. Typically, that information includes your name, Social Security number and zip code. American Express, for example, asks for your Social Security number and zip code. The issuer might also require you to fill out a CAPTCHA or answer a security question to prevent spam. For example, the Bank of America site asks you to answer a simple math question.
