Millions of Discover credit card accounts will soon be migrated to Capital One’s systems, the latest move as part of a $35 billion merger between the two companies. For some, the transition is imminent: Although an FAQ page says Discover card accounts will transition “during 2026 and early 2027,” many customers have been told to mark July 27 as their 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 transferred to Capital One for management.” The company hasn’t confirmed which cards will move first.
This comes as Capital One completed its acquisition of Discover in May 2025. The integration of the two financial giants is proving to be as complicated as it sounds.
Capital One will retain the Discover brand but will integrate Discover accounts into Capital One’s existing credit card systems. This means that the Discover website and app will no longer be the access point for customer accounts. However, the company will continue to market credit cards through Discover.com.
Current Discover cardholders can continue to use their physical cards with the same 16-digit numbers during the transition. Credit card product names will not change and Discover credit card customers will retain their annual fees, APRs and $0 credit limits. The reward and redemption rates also remain largely unchanged.
Capital One has published dozens of FAQs informing customers exactly what’s changing—and what’s staying the same. So if you have an affected Discover card, here are five things you should do now:
Table of Contents
1. Download the Capital One app
The biggest change in card switching has to do with logistics: Instead of signing up for account services on the Discover website and mobile app, customers use Capital One to manage their accounts.
Discover cardholders can’t sign up through Capital One yet. While they wait for access, they can prepare for the transition by downloading the Capital One mobile app.
“Customers will receive detailed communications from us about when and how they can start using Capital One. There is no need for them to do anything until then,” says a Capital One spokesperson. “But we encourage customers to ensure their contact information – including address, phone number and email – is current in their Discover account, as well as their other settings and account preferences.”
This information will be transferred to the Capital One system in due course.
2. Confirm your payment due date
Do you know the current due date of your Discover card payment – the deadline you must meet each month to avoid fees? If not, make a note of it.
When cards are migrated to the Capital One system, most payment dates 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 will only be pushed back, not moved up.
“The transition to Capital One systems will not negatively impact Discover cardholders’ credit scores,” the spokesperson added. “The migration will not be reported as a new account and the account opening date will appear as the same date currently on a cardholder’s credit file.”
Automatic credit card payments are not interrupted in most cases, according to Capital One. However, customers using autopay should double-check their settings before and after the migration to ensure the payment is transferred correctly.
“If we are unable to transfer your automatic payments to Capital One, we will inform you by email or letter,” an FAQ says.
3. Watch out for disappearing features
Discover cardholders may lose access to several minor features if their accounts are migrated.
For example, customers can no longer have premiums credited towards their minimum payments. Rewards can still be redeemed for a statement credit to reduce your balance, but this option does not meet the minimum payment requirements.
While cardholders can still redeem rewards for gift cards, there is a higher redemption minimum of $25 for gift cards, up from $5 previously at Discover.
Additionally, the Pay with Rewards feature in Apple Pay will no longer be available after migrating to Capital One and recurring Apple Pay subscriptions may be interrupted.
4. Refresh your new benefits
Credit card terms and rewards structures remain largely the same. Capital One touts several features that Discover cardholders get, 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 can access Capital One’s CreditWise, which offers similar features.
Further changes are intended to give cardholders more flexibility. For example, Discover It Miles accounts get access to gift card redemption. Discover cardholders can also access additional features such as Capital One virtual card numbers and spending management tools, the company said.
5. Be on the lookout for new authorized user cards
Unlike primary Discover cardholders, authorized users and shared account holders will receive new physical cards with unique 16-digit numbers. (Previously, authorized Discover users shared the primary cardholder’s card number.)
The new cards will be mailed to the primary account holder.
“We will notify the primary cardholder when the new cards are on the way,” an FAQ says. “Until then, those entitled and co-account holders can continue to use their existing card.”
When the new cards arrive, these additional users will be able to create their own online Capital One accounts.
