Discover Bank checking accounts are being turned into Capital One 360 Checking accounts one account at a time, and each one gets a Capital One routing number. Capital One says wires sent to a converted account with the old Discover routing number “will be returned,” so anyone expecting a wire has to hand out the new number first.
The account number stays the same, according to Capital One’s page for Discover checking customers. Only the nine-digit routing number changes, and customers learn when their turn comes by email or letter.
Routing numbers change, and wires are the exception
Capital One’s page lists the routing number as the main thing that changes on a checking account. It also lists the wire rule in plain terms: customers “will need to use Capital One’s routing number for wire transfers” or the wires come back to the sender.
That rule matters most for anyone who receives money by wire, such as proceeds from the sale of a house, a payout from a brokerage or a transfer from a relative abroad. A wire sent to the old Discover number after conversion does not land in the account. It is returned, and the delay can cost a closing date. The question for each Discover checking customer is whether any money is due by wire, and if so, which date the account converts.

The same page says scheduled checks, transfers set up through Discover and direct deposits “will still be completed” and keep working with the old routing number. Capital One has not said how long that old number will keep working for those payments.
What stays the same on a converted checking account
The company says the Discover debit card keeps working, and that Zelle payments continue on the Capital One account. Cash access widens to what Capital One calls more than 70,000 fee-free Capital One, MoneyPass and Allpoint ATMs. Capital One says the new account has no monthly fee and no minimum balance.
Zelle limits are spelled out once a customer signs in and agrees to the terms: up to $3,000 a day and $12,500 a month. Apps such as PayPal, Venmo and Robinhood have to be relinked to the account, and the company’s bank FAQ for converted Discover accounts says that step has to be repeated each time an account moves to a new product.
What gets worse: interest and cash back
The checking account becomes a Capital One 360 Checking account paying a variable 0.10% APY, according to the same FAQ. The rate is listed as effective September 10, 2026 and subject to change at any time. For an account carrying a few thousand dollars, that is a few dollars a year.
Cashback Debit rewards end. Capital One says 360 Checking accounts do not offer rewards on debit card purchases. Unredeemed rewards are paid out before the conversion, either as a statement credit on the Discover checking account or into a designated savings account. A one-time deposit equal to the rewards from the last 12 statements follows within 30 days of the conversion, and Capital One says the exact qualifying dates will arrive in a separate communication.
The company has not published a single conversion date for checking. It says to keep using the Discover account as usual until the notice arrives saying that account is ready. Anyone with more than one Discover account may get separate notices for each, because the savings, money market and CD products convert on their own tracks with their own changes.
For a household that has used the Cashback Debit card for everyday spending, the practical effect is that the reward on each purchase stops once the switch happens. Balances on the account earn 0.10% interest after that.
Where the change came from
Capital One completed its acquisition of Discover Financial Services on May 18, 2025, according to the company’s announcement. That day it said Discover and Capital One customer accounts “remain unchanged” for the time being, and the banking conversions have followed in stages since.
The checking conversion is separate from the card moves and from the savings changes, which carry their own rules. Each product line has its own notice, its own list of changes and its own timing, so a customer with a card, a checking account and a CD may get three different messages.
A short list of what to update when the notice arrives
Anyone who receives wires should send the new routing number to the sender as soon as the notice arrives. Payroll and pension offices can be told the new number too, although direct deposits sent to the old number are still supposed to arrive. Third-party apps linked to the account need a fresh login connection.
People who get Social Security can update the bank details with the Social Security Administration. The agency says the fastest route is an online Social Security account. It also takes updates by phone at 1-800-772-1213 on weekdays from 8 a.m. to 7 p.m. (TTY users call 1-800-325-0778) or through a bank that offers the Automated Enrollment process. Nothing there says an update is required when only the routing number changes, so it is a question for the agency if a payment ever bounces.
The main protection is a paper trail. Keeping the date of the notice, a printout of the new account details and a note of the first deposit after conversion gives a customer something to show the bank if a payment goes missing.
Will the Social Security deposit still land after the switch?
Capital One says direct deposits keep working during the move, but a conversion is the kind of change where a deposit can be held or a balance can be restricted for a few days. For someone living on Social Security, a few days of an unreachable balance can mean a missed rent payment.
The Bank Account & Debt Protection Kit turns from the routing change to that wider question. It explains the 2-month bank protection rule that guards federal benefits already in an account, and the frozen-account response to follow if a bank or a creditor locks the balance.
