Your Discover account number is a unique 16-digit code printed on your Discover card or visible in your online account
The account number appears on the front of your physical card, usually in raised digits below the cardholder name. If you have a Discover debit card, the number is there. If you have a Discover credit card, the number is there. The digits are the same whether you look at the card itself or log into your Discover account online.
You need this number when you make a purchase over the phone, set up automatic payments, or contact Discover customer service about your account. It is also the number you use to link your Discover account to another bank or payment app.

Finding your account number on your physical card
Look at the front of your Discover card. The 16-digit number is embossed (raised) in the center-lower area of the card, directly below your name. The digits are printed in a standard font and are easy to read. This is your account number.
The back of your card has a different number — the three-digit security code (CVV) — which is not your account number. The security code is used only for online and phone purchases, not for identifying your account itself.
Finding your account number online
Log into your Discover account at discover.com using your username and password. Once you are signed in, go to the account details or card information section. Your 16-digit account number will be displayed there, usually with the last four digits visible and the first digits masked for security.
If you have multiple Discover cards or accounts, each one has its own account number. The online portal will show you the number for whichever card or account you select.
When you need your account number
Use your account number when you make a purchase by phone and the merchant asks for your card number. You will also need it if you are setting up automatic bill pay through your bank and want to pay your Discover bill from another account. Discover customer service will ask for your account number (or the last four digits) when you call to report a problem, dispute a charge, or ask about your account.
Some payment apps and digital wallets may ask for your account number when you link your Discover card to them. Always verify you are using a secure connection before entering this information.
What to do if you cannot find your account number
If your card is damaged and the number is not readable, or if you do not have your physical card with you, log into your Discover account online. The account number is always visible there. If you cannot access your online account, call Discover customer service at the number on the back of your card (or on your billing statement) and they will provide your account number over the phone after verifying your identity.
If your card is lost or stolen, do not wait to find the account number. Call Discover immediately to report it. They will cancel the card and issue a replacement with a new account number. You can still access your account online during this time.
Protecting your account number
Your account number is sensitive information. Do not share it with anyone except Discover or a merchant you are actively paying. Do not write it down and leave it visible, and do not text or email it to anyone. If someone calls claiming to be from Discover and asks for your full account number, hang up and call Discover directly using the number on your card or statement — legitimate companies do not ask for full account numbers unsolicited.
If you believe your account number has been compromised or used without your permission, contact Discover right away. They can monitor your account for fraud and issue a new card if needed.
Frequently Asked Questions
Is my account number the same as my card number?
Yes. Your Discover account number and your card number are the same 16-digit code. The terms are used interchangeably. When a merchant asks for your card number, they are asking for your account number.
What if I have multiple Discover cards?
Each Discover card has its own unique 16-digit account number. If you have two Discover cards linked to the same account, they will have different numbers. Log into your online account to see all your cards and their respective numbers.
Can I use my account number to make a purchase online?
Yes. When you enter your card information on a website, you enter your 16-digit account number along with the expiration date and CVV (the three-digit security code on the back). Always make sure the website is secure before entering this information.
What should I do if my card is compromised?
Call Discover immediately using the number on the back of your card or your statement. Report the fraud or unauthorized use. Discover will cancel the card and send you a replacement with a new account number. You are not responsible for fraudulent charges once you report them.
Is the account number on my billing statement?
Your billing statement usually shows only the last four digits of your account number for security reasons. To see your full 16-digit number, check your physical card or log into your online account.
