What you need to open a Capital One savings account
Capital One offers savings accounts online through their website or mobile app. To open one, you need a Social Security number, a valid government-issued ID, a current mailing address, and a way to fund the account—either a debit card, bank account, or wire transfer. You can complete the entire process on your phone or computer in about 10 minutes.
Capital One does not require a minimum opening deposit, though you will need to fund the account with at least $0.01 to activate it. There is no monthly maintenance fee. The account comes with a debit card that arrives by mail within 7 to 10 business days.
You do not need to visit a branch. Capital One operates as an online bank, so all account opening, deposits, withdrawals, and customer service happen through their website, app, or phone line.

Step-by-step: opening the account online
Go to capitalone.com or open the Capital One mobile app. Look for the button that says "Open an Account" or "Open a Savings Account." You will be asked to enter your email address and create a password. Capital One will send a verification code to that email—check your inbox and enter the code to continue.
Next, enter your full name, date of birth, Social Security number, and current mailing address. Capital One will verify this information against public records. If you have moved recently or your name appears differently on your ID, have that document ready.
You will then choose how to fund the account. If you have a bank account at another bank, you can link it by entering your routing number and account number (found on a check or your bank's website). If you prefer to use a debit card, enter the card number, expiration date, and CVV. Wire transfers are also an option if you are funding from a business account or international source.
Review the account terms and disclosures, then submit. Capital One will send a confirmation email. Your account is live immediately, though transfers from another bank account may take 1 to 3 business days to complete. Your debit card ships separately and arrives within 7 to 10 business days.
What happens if your application is declined
Capital One checks your identity and runs a soft credit inquiry, which does not affect your credit score. Most applications are approved instantly. If yours is declined, Capital One will send an email explaining the reason—usually a mismatch between the information you entered and public records, or a duplicate account under your name.
If the issue is a name mismatch (for example, you go by a nickname but your ID shows your full legal name), call Capital One at 1-800-655-9541 and explain. They can often override the decline. If you already have a Capital One account, you cannot open a second one; you would need to close the existing account first.
If your application is declined and you believe the reason is incorrect, ask Capital One for the specific reason in writing. You have the right to know why you were denied.
Funding your account and moving money in
Once your account is open, you can deposit money through several methods. The fastest is a transfer from another bank account you own—this takes 1 to 3 business days. You can also deposit by debit card, which is instant. Wire transfers are available if you are funding from a business account or sending money from abroad.
Capital One also offers direct deposit. If your employer or a government agency (such as Social Security) sends you regular payments, you can set up direct deposit to your Capital One account. Ask your employer or benefits administrator for Capital One's routing number (310087662) and your account number, which you can find in the app or on your statement.
There are no limits on how much you can deposit or how often. You can also transfer money out to another bank account you own, though Capital One limits outgoing transfers to 6 per month (this is a federal rule that applies to all savings accounts).
Interest rates and how your money grows
Capital One savings accounts earn interest on your balance. The rate is set by Capital One and changes based on Federal Reserve decisions and market conditions. You can see the current rate on their website before you open the account.
Interest is calculated daily and deposited monthly. This means if you have $1,000 in the account for the entire month, you earn interest on that $1,000. If you deposit $500 more halfway through the month, the second half of the month earns interest on $1,500. The interest compounds, so you earn interest on your interest.
Capital One reports your interest earnings to the IRS on a Form 1099-INT if you earn $10 or more in a year. You will receive this form by January 31 and will need to report the interest as income on your tax return.
Security and fraud protection
Capital One uses encryption to protect your information when you log in online or through the app. Your login is protected by a password you create. You can also set up two-factor authentication, which sends a code to your phone or email every time you log in from a new device.
If someone uses your debit card without permission, report it to Capital One immediately. Call 1-800-655-9541 or use the app to report fraud. Capital One will cancel the card and issue a replacement. You are not liable for unauthorized charges if you report them promptly.
Capital One is a bank insured by the Federal Deposit Insurance Corporation (FDIC). This means your deposits up to $250,000 are protected if the bank fails. If you have multiple accounts at Capital One (such as a savings account and a checking account), the $250,000 protection applies to each account type separately.
Accessing your account and managing it
You can access your Capital One savings account 24/7 through the website or mobile app. You can check your balance, view transactions, transfer money, and change your settings anytime. The app is available for iPhone and Android.
You can also call Capital One customer service at 1-800-655-9541. They are available 24 hours a day, 7 days a week. Have your account number and a form of ID ready when you call.
Your debit card can be used at any ATM that accepts Mastercard. Capital One does not own ATMs, so you may be charged a fee by the ATM operator if you use an out-of-network machine. Check the Capital One app or website for a list of in-network ATMs in your area.
Frequently Asked Questions

Can I open an account if I do not have a Social Security number?
No. Capital One requires a Social Security number to open an account. If you are not a U.S. citizen or permanent resident, you may not be able to open an account. Contact Capital One directly to discuss your situation.
How long does it take to access my money after I deposit it?
Transfers from another bank account take 1 to 3 business days. Debit card deposits are instant. Direct deposits from your employer or benefits administrator take 1 to 2 business days. Once the money is in your account, you can transfer it out or withdraw it immediately.
What happens if I close my account?
You can close your Capital One savings account anytime by calling customer service or using the app. If you have money in the account, Capital One will transfer it to the bank account you specify. The debit card will stop working once the account is closed.
Can I have more than one Capital One savings account?
No. Capital One allows only one savings account per person. If you need multiple accounts for different purposes, you would need to use a different bank for the second account.
