Millions of Discover credit card accounts will soon be migrated to Capital One's systems, the latest step in a $35 billion merger of the two companies. For some, the switch is imminent: Although an FAQ page says Discover card accounts will move "throughout 2026 and early 2027," many customers have been told to mark July 27 as the transition date.
A Capital One spokesperson confirms to Money that the migration will occur in waves, adding that "all Discover consumer card accounts will gradually be transitioned to Capital One to manage." The company did not confirm which cards will move first.
Must Read
This is happening because Capital One completed its acquisition of Discover in May 2025. Integrating the two financial behemoths is proving to be as complicated as it sounds.
Capital One is keeping the Discover brand but folding Discover accounts into Capital One's existing credit card systems. This means the Discover website and app will no longer be the point of access for customers' accounts. The company will, however, continue marketing credit cards at Discover.com.
Current Discover cardholders can continue using their physical cards with the same 16-digit numbers throughout the transition. Credit card product names will not change, and Discover credit card customers will keep their $0 annual fees, APRs and credit limits. Rates for earning rewards and redemption options will also remain largely unchanged.
Capital One has published dozens of FAQs guiding customers through exactly what is changing — and what is staying the same. So if you have an affected Discover card, here are five things to do now:
1. Download the Capital One app
The biggest change when cards switch has to do with logistics: Instead of logging into the Discover website and mobile app for account services, customers will use Capital One to manage their accounts.
Discover cardholders are not yet able to log in through Capital One. While waiting for access, they can prepare for the transition by downloading the Capital One mobile app.
"Customers will receive detailed communications from us regarding when and how to get started with Capital One. Until then, there's nothing they need to do," a Capital One spokesperson says. "But we encourage customers to ensure their contact information — including address, phone number and email — is up to date in their Discover account, along with their other settings and account preferences."
That information will be ported over to the Capital One system when the time comes.
2. Confirm your payment due date
Do you know your current Discover card payment due date, meaning the deadline you have to meet every month in order to dodge fees? If not, make a note of it.
When cards migrate to the Capital One system, most payment dates will remain the same. However, Capital One said on its website that some due dates will be adjusted "to avoid technical issues," and affected customers will be notified.
The good news: A Capital One spokesperson confirms that due dates are only being pushed out, not moved up.
"The transition to Capital One systems will not negatively affect Discover cardholders’ credit scores," the spokesperson adds. "The migration will not be reported as a new account, and the account open date will appear as the same date currently reported on a cardholder’s credit file."
Where You Can Fix Your Credit Right Now
Automatic credit card payments will not be interrupted in most cases, according to Capital One. Still, customers who use autopay should double-check their settings before and after the migration to ensure that the payment carries over correctly.
"If we're not able to transfer your automatic payments to Capital One, we'll let you know by email or letter," an FAQ reads.
3. Be aware of disappearing features
Discover cardholders may lose access to several minor features when their accounts migrate.
For instance, customers will no longer be able to apply rewards toward their minimum payments. Rewards will still be redeemable for a statement credit to reduce your balance, but that option will not satisfy minimum payment requirements.
While cardholders can continue to redeem rewards for gift cards, redemptions will be subject to a higher gift card minimum of $25, up from $5 before with Discover.
Also, the "Pay with Rewards" feature in Apple Pay will no longer be an option after the migration to Capital One, and Apple Pay recurring subscriptions may be disrupted.
4. Brush up on your new benefits
For the most part, credit card terms and rewards structures stay the same. Capital One is touting several features that Discover cardholders will gain, including access to Capital One Travel (with 5% cash back or 5X miles on hotels and rental cars booked through the portal), Capital One Entertainment (a ticketing platform), and Capital One Offers (its shopping rewards program).
Cardholders who use Discover's credit monitoring will be able to access Capital One's CreditWise, which offers similar functionality.
Other changes are intended to give cardholders more flexibility. For example, Discover It Miles accounts will gain access to gift card redemptions. Discover cardholders will also be able to access additional features like Capital One's virtual card numbers and spend management tools, the company says.
5. Look out for new cards for authorized users
Unlike primary Discover cardholders, authorized users and joint account holders will receive new physical cards with unique 16-digit numbers. (Previously, Discover authorized users shared the primary cardholder's card number.)
The new cards will be mailed to the main account holder.
"We will let the primary cardholder know when the new cards are on their way," an FAQ reads. "Until then, authorized users and joint account holders can continue using their current card."
When the new cards arrive, those additional users will be able to create their own online Capital One accounts.
