Your Discover account number is on your card, your statement, and in your online account
The fastest place to find your Discover account number is the front of your physical card — it is the 16-digit number printed below your name. If you do not have the card in front of you, your monthly statement shows it near the top, usually labeled "Account Number" or "Card Number". You can also log into your Discover online account or mobile app and find it in the account details or settings section.
Discover account numbers are not the same as your routing number or your Discover customer service PIN. The account number is what identifies your specific card or credit line to merchants and to Discover itself. You will need it when you make a payment, dispute a charge, or contact customer service about your account.
Key Takeaways
- Your Discover account number is the 16-digit number on the front of your card, below your name.
- Paper statements show your account number near the top, usually in a section labeled "Account Number" or "Card Number".
- You can view your account number by logging into your Discover online account or opening the Discover mobile app.
- Never share your full account number with anyone who contacts you by phone or email, even if they claim to be from Discover.
Finding your number on your physical card
Look at the front of your Discover card. The 16-digit number printed below your name is your account number. The digits are usually arranged in four groups of four. This is the number you use when you swipe, insert, or tap your card at a store or online.
If your card is damaged, expired, or lost, you can still find your account number through your statement or online account. Discover will send you a replacement card with the same account number, so you do not need a new number just because your physical card changed.
Checking your monthly statement
Open your most recent Discover statement — either the paper copy mailed to you or the PDF version in your online account. Near the top of the first page, you will see a section that lists your account details. Your account number appears there, usually labeled clearly as "Account Number" or sometimes as "Card Number".
Statements are useful when you need your account number but do not have your card. You can download past statements from your Discover account online going back several years, so if you need to reference an old number, you can retrieve it that way.
Logging into your Discover online account
Go to discover.com and sign in with your username and password. Once you are logged in, look for a section labeled "Account" or "Account Details" — the exact location varies depending on whether you are using the website or the mobile app. Your account number will be displayed there along with your current balance, credit limit, and other account information.
The Discover mobile app also shows your account number. Open the app, tap on your account or card details, and you will see the 16-digit number. This method works even if you do not have your physical card with you.
What to do if you cannot find your account number
If you have tried the card, statement, and online account and still cannot locate your number, contact Discover customer service. You can call the number on the back of your card, or use the "Contact Us" option in your online account. Have your Social Security number and date of birth ready — Discover will verify your identity before providing your account number over the phone.
Do not give your account number to anyone who calls or emails you first, even if they say they are from Discover. Legitimate Discover representatives will never ask you to confirm your full account number unsolicited. If someone contacts you claiming to be from Discover and asks for your account number, hang up and call the number on the back of your card instead.
Keeping your account number secure
Your account number is sensitive information. Share it only when you are making a payment, disputing a charge, or contacting Discover directly through their official phone number or website. Do not share it in emails, texts, or over the phone unless you initiated the contact.
If you suspect someone has your account number, contact Discover right away. They can monitor your account for fraud and issue you a new card with a new account number if needed. The sooner you report it, the sooner they can protect your account.
Frequently Asked Questions
Is my account number the same as the CVV on the back of my card?
No. Your account number is the 16-digit number on the front of your card. The CVV is the three-digit security code on the back. They are different numbers used for different purposes.
Can I change my Discover account number?
You cannot change your account number yourself, but Discover will issue you a new one if you request a replacement card. The new card will have a new account number. You would do this if you suspect fraud or if you want a fresh number for security reasons.
Do I need my account number to make an online purchase?
Yes, most online retailers ask for your full card number (which is your account number), expiration date, and CVV when you check out. Some retailers may also ask for your billing zip code or other verification information.
What if I have multiple Discover cards?
Each Discover card you have will have its own unique 16-digit account number. If you have more than one card, each one identifies a separate account or credit line. Your statement will show which account number belongs to which card.
Can I find my account number through the Discover app if I am not logged in?
No. You must log in to your Discover account to view your account number through the app or website. This is a security measure to protect your information.
