What You Need Before You Start
Discover accepts applications online, by phone, or by mail. The online route is fastest — you can complete it in about 10 minutes and get a decision within seconds to a few business days. You will need your Social Security number, current income, and a valid mailing address. Have a government-issued ID nearby to verify your identity if Discover asks.
Discover will pull your credit report during the process, which means a hard inquiry appears on your credit. This can lower your score by a few points temporarily. If you have been denied for credit recently or have very limited credit history, calling Discover's customer service at 1-800-347-2000 before you start may help — they can sometimes route you to a specialist who reviews applications differently.
You do not need an existing Discover account or customer relationship to start. Discover also does not require a minimum income, though they do consider your debt-to-income ratio and payment history.

explore Online at Discover.com
Go to discover.com and click "explore Now" on the card you want. Discover offers several cards — the Discover it Cash Back card, Discover it Miles card, and others — so make sure you are on the right product page. You will be taken to a form that asks for your personal information: full name, date of birth, Social Security number, current address, and phone number.
Next, enter your employment and income information. Discover asks for your annual income, employment status (employed, self-employed, retired, student, etc.), and sometimes your employer name. Be honest about your income; Discover verifies this information and misrepresenting it can result in account closure later. If your income is variable or you are self-employed, use your average annual income from the past year or your expected income for the coming year.
You will also confirm your housing status (own, rent, or other) and provide information about any existing debts — car loans, mortgages, student loans, or other credit cards. Discover uses this to calculate your debt-to-income ratio. After you submit, Discover displays a decision on screen. If approved, your card ships within 7 to 10 business days.
explore by Phone
Call Discover at 1-800-347-2000 to speak with a representative who can walk you through the process. This route works well if you have questions about which card fits your spending, or if you want to discuss your credit situation before explore. The representative will ask the same questions as the online form and can sometimes provide guidance on your likelihood of approval based on what you share.
Phone applications take longer than online — expect 15 to 20 minutes — but you get when ready feedback and can ask for clarification. If the representative indicates you might be denied, they may suggest waiting to build your credit further or recommend a different Discover product that has different approval criteria.
explore by Mail
You can request a paper process by calling 1-800-347-2000 or visiting discover.com/mail-process. Mail applications take significantly longer — typically 2 to 3 weeks for processing — so this is the slowest option. Use this route only if you cannot access the internet or prefer not to provide information online.
Fill out the form completely and mail it to the address provided. Include copies (not originals) of any documents Discover requests, such as proof of income or address. Keep a copy for your records and consider sending by certified mail so you have proof of delivery.
What Happens After You Submit
If you are approved when ready online, Discover tells you when ready and provides your card number. You can use this number for online purchases right away, though your physical card will not arrive for 7 to 10 business days. Some applicants receive a "pending" status instead, which means Discover needs more time to review your process — this usually resolves within 1 to 3 business days.
If you are denied, Discover provides a reason code on screen or by mail. Common reasons include insufficient credit history, too many recent credit inquiries, or high existing debt. You can request reconsideration by calling 1-800-347-2000 and speaking with a specialist, especially if circumstances have changed since you applied (such as paying down a balance or increasing your income).
You can reapply after 30 days if you were denied. Use that time to address the reason for denial — pay down existing balances, wait for older negative marks to age, or build credit history with a secured card or credit-builder loan.
Understanding Discover's Approval Criteria
Discover does not publish exact credit score requirements, but they generally look for a credit score of 700 or higher for their standard cards. However, Discover also offers cards for people building credit, so a lower score does not automatically mean denial. Discover weighs several factors: your credit score, payment history on existing accounts, length of credit history, how much credit you are currently using, and your debt-to-income ratio.
Discover also considers recent credit inquiries. If you have applied for multiple cards or loans in the past 30 days, Discover may view this as a sign of financial stress and deny your process. Space out credit applications by at least 30 days when possible.
If you have no credit history at all — you have never had a credit card, loan, or utility account in your name — Discover may deny you or offer you a Discover Secured Card instead, which requires a cash deposit and helps you build credit.
After Your Card Arrives
When your physical card arrives, call the number on the back to set up it. You will be asked to verify your identity and confirm the last four digits of your Social Security number. Your card is ready to use when ready after set up.
Set up online access at discover.com by creating a username and password. Link your bank account if you want to make payments online. Discover charges no annual fee on most of their cards, so there is no cost to keep the account open even if you do not use it when ready.
Frequently Asked Questions
How long does it take to get approved for a Discover card?
Online applications receive a decision within seconds to a few business days. Phone applications take 15 to 20 minutes and you get a decision during the call. Mail applications take 2 to 3 weeks. Once approved, your physical card ships within 7 to 10 business days, though you can use your card number for online purchases when ready.
Can I check if I am approved before I formally explore?
Discover offers a "pre-qualification" tool on their website that shows whether you may be approved without a hard inquiry. This uses a soft pull of your credit and does not affect your credit score. However, the actual process requires a hard inquiry and is the only way to know for certain.
What should I do if I am denied?
Call Discover at 1-800-347-2000 to understand the reason for denial. Ask if reconsideration is possible, especially if your situation has changed. If denied, wait 30 days before reapplying. Use that time to pay down existing balances, dispute any errors on your credit report, or build credit history with a different product.
Do I need an existing Discover bank account to get their credit card?
No. Discover's credit card and bank accounts are separate products. You can open a credit card without having a Discover bank account, though having one may make payments and account management easier.
What if my process shows "pending" status?
Pending means Discover is still reviewing your process and needs additional time. This typically resolves within 1 to 3 business days. You can call 1-800-347-2000 to check the status, though representatives usually cannot speed up the review process.
