You can get a Discover Card by applying online, by phone, or by mail, and most decisions come back within minutes

Discover accepts applications through its website, over the phone at 1-800-347-2683, or by mailing a paper form. Online is fastest — you'll know if you're approved or denied before you finish. Phone applications take about 15 minutes. Paper applications take 7 to 10 business days to process. You'll need your Social Security number, income information, and a valid ID to start any application.

Discover pulls your credit report as part of the decision, so the approval depends on your credit score, payment history, and how much debt you already carry. There's no minimum credit score published by Discover, but most cardholders have scores of 650 or higher. If you're denied, Discover will tell you why and you can reapply after addressing the issue — usually by paying down existing debt or waiting for negative marks to age off your report.

Key Takeaways

  • Online applications are processed in minutes, while phone applications take about 15 minutes and paper applications take 7 to 10 business days.
  • You'll need your Social Security number, current income, and a valid government ID to complete any application.
  • Discover will check your credit report, so your approval depends on your credit score and existing debt levels.
  • If you're denied, you can ask Discover why and reapply once you've addressed the issue, usually by reducing debt or waiting for negative marks to age.
  • Your card arrives by mail within 7 to 10 business days after approval, and you can activate it online or by phone before it arrives.

What information you need before you start

Have your Social Security number, current annual income, and a valid government-issued ID ready before you open the application. Discover also asks for your employment status, current address, and phone number. If you've moved in the last two years, be ready to provide your previous address.

If you're applying by phone, have this information in front of you so you don't have to search for it mid-call. Online applications let you save your progress and come back, but you'll still need all the same details to finish. The application itself takes 5 to 10 minutes once you have everything together.

How Discover decides whether to approve you

Discover pulls your credit report from one or more of the three major credit bureaus — Equifax, Experian, or TransUnion. The company looks at your credit score, how long you've had credit accounts open, whether you've paid bills on time, and how much of your available credit you're currently using. A higher score and a longer history of on-time payments make approval more likely.

Discover also considers your income and how much debt you already owe. If you have very high debt relative to your income, you may be denied even with a good credit score. The company doesn't publish exact thresholds, so there's no way to know for certain before you apply. If you're denied, the rejection letter will explain the main reason — usually "insufficient credit history," "too many recent inquiries," or "high existing debt."

Applying online through Discover's website

Go to discover.com and click "Apply Now" on the card you want. You'll enter your personal information, income, and employment status on a secure form. The application asks whether you want the card for balance transfers, cash back, or general use — this doesn't lock you into anything, it just helps Discover route your application.

After you submit, Discover's system checks your credit instantly and gives you a decision on the same screen. If you're approved, you'll see your credit limit and can activate your card immediately, even though it won't arrive by mail for 7 to 10 business days. If you're denied or put on a waiting list, you'll see that decision too, along with a phone number to call if you want to discuss it.

Applying by phone or mail if you prefer not to apply online

Call 1-800-347-2683 to speak with a Discover representative who will walk you through the application over the phone. Have your information ready and expect the call to take about 15 minutes. The representative will ask the same questions as the online form and can answer questions about different card options while you're on the line. You'll get a decision before you hang up.

For a paper application, call the same number and ask for a form to be mailed to you, or visit a Discover branch if one is near you. Paper applications take longer to process because they have to be reviewed by hand, so expect 7 to 10 business days for a decision. Once approved, your card will be mailed separately and should arrive within another 7 to 10 business days.

What happens after you're approved

Your approval letter will include your credit limit and a temporary card number you can use to make purchases right away, even before your physical card arrives. You can activate your card online at discover.com or by calling 1-800-347-2683. Activation takes less than a minute and you can start using your card immediately after.

Your physical card will arrive by mail within 7 to 10 business days. When it arrives, sign the back and activate it if you haven't already. Your first statement will show any purchases you made with the temporary number, and you'll have a due date to pay at least the minimum amount. Discover sends statements monthly and you can view them online anytime through your account.

If you're denied or placed on a waiting list

A denial doesn't mean you can never get a Discover Card. The most common reasons for denial are a credit score below 650, too many recent credit inquiries, or existing debt that's too high relative to your income. You can reapply after addressing the issue — usually by paying down debt, waiting a few months for recent inquiries to age off your report, or building your credit score.

If you're placed on a waiting list instead of denied outright, Discover will review your application again in 30 days. You don't need to do anything; the company will contact you with a decision. In the meantime, avoid opening new credit accounts or taking on new debt, as that can hurt your chances when they review again.

Frequently Asked Questions

How long does it take to get approved for a Discover Card?

Online applications get a decision in minutes. Phone applications take about 15 minutes and you get a decision before you hang up. Paper applications take 7 to 10 business days. Once approved, your physical card arrives by mail in another 7 to 10 business days, but you can use a temporary card number immediately.

What's the minimum credit score to get a Discover Card?

What do I do if my application is denied?

Your denial letter will explain the reason — usually low credit score, high existing debt, or too many recent credit inquiries. You can reapply after addressing the issue, typically by paying down debt or waiting a few months. You can also call Discover at 1-800-347-2683 to discuss your application and ask what would improve your chances.

Do I need to have a bank account with Discover to get their credit card?

No. Discover's credit card and its banking products are separate. You can get a Discover Card without having a Discover savings account or checking account. However, having an existing relationship with Discover may make approval slightly more likely.
