In general, when you fill out a credit card application, they need to know the same information: your contact info including street address and phone number, your social security number, and your annual income. You can fill out applications online and get an answer within minutes in most cases. You can also fill out a paper application and mail it in, if you prefer old school style. Or if you are applying for a store credit card, you might simply give the information verbally to the cashier, who will put in the application for you. Be sure to safeguard all personal information when applying for a credit card of any kind, no matter how you are applying. It’s best to apply online, over a secure Wi-Fi connection, on a site with an up-to-date security certificate that encrypts your information when you send it, to protect you from hackers.
