You need a Social Security number, a valid ID, and an initial deposit to open a Capital One 360 High Yield Savings account online
Capital One 360 is an online bank, so the entire process happens through their website or mobile app — there are no branches to visit. You will need to provide your Social Security number, a government-issued ID (driver's license or passport), your current address, and your date of birth. Capital One will verify this information against their systems and run a soft credit check, which does not affect your credit score.
The account opens when ready once you complete the verification steps, usually within minutes. You can then fund it by transferring money from another bank account, or by having your employer or another source deposit money directly into it. Capital One does not require a minimum opening deposit, but you will need at least some money in the account to start earning interest.
The entire process takes about 15 to 20 minutes from start to finish if you have your documents ready. You do not need to visit a branch, call anyone, or mail anything in.

What documents and information you need before you start
Gather these items before you begin the online process: your Social Security number, a government-issued photo ID (driver's license, passport, or state ID card), your current street address, and your date of birth. You will also need access to an email address and a phone number where Capital One can reach you.
If you plan to fund the account by transferring money from another bank, have that bank's routing number and your account number ready. You can find both on a check or by logging into your other bank's website. If you plan to use direct deposit instead, you can set that up after the account opens — you do not need that information right now.
The step-by-step process to open your account
Go to capitalone.com and select "Open an Account" or use the Capital One 360 mobile app. Choose "High Yield Savings" as your account type. Enter your email address and create a password for your online login.
On the next screen, enter your personal information: full name, date of birth, Social Security number, and current street address. Capital One will ask whether you are a U.S. citizen and whether you have been convicted of certain financial crimes — answer honestly, as these are standard banking questions.
Capital One will then verify your identity by checking your information against databases they use. This usually happens when ready. If there is any issue, they will ask you to upload a photo of your ID — take a clear photo of the front and back of your driver's license or passport and upload it through their website.
Once verification is complete, you will see your new account number and routing number on the screen. Write these down or take a screenshot. You can now fund the account by transferring money from another bank account, or you can skip this step and fund it later.
How to fund your new account
Capital One offers two main ways to add money: external transfer and direct deposit. An external transfer moves money from your checking or savings account at another bank into your Capital One account. Direct deposit sends money from your employer or another source directly into Capital One.
To set up an external transfer, log into your Capital One account and select "Transfer Money." Choose "From another bank" and enter your other bank's routing number and your account number at that bank. Capital One will ask you to verify the transfer by making two small deposits (usually under $1 each) to that account, then entering the amounts back into Capital One. This verification process takes one to two business days.
To set up direct deposit, ask your employer or the organization sending you money for Capital One's routing number and your account number. You can find both in your Capital One account under "Account Details." Give these to your employer, and they will set up the deposit on their end — this usually takes one to two pay periods to begin.
What happens after your account opens
Your account is ready to use when ready, but money you transfer from another bank may take one to three business days to arrive, depending on how you send it. Direct deposits typically arrive on the same schedule as they would at any other bank.
Once money is in your account, it begins earning interest at Capital One's current rate. The rate changes periodically — Capital One does not lock in a rate when you open the account, so the interest you earn will go up or down as the market changes. You can check your current rate and interest earned by logging into your account.
You can withdraw money from your Capital One account at any time without penalty. Transfers to another bank take one to three business days. You can also use an ATM if you have a Capital One debit card, though Capital One does not issue physical debit cards for savings accounts — you would need to open a checking account to get one.
Why Capital One 360 High Yield Savings might or might not fit your needs
Capital One 360 is entirely online, which means lower overhead costs and higher interest rates than traditional banks. The tradeoff is that you cannot walk into a branch or speak to someone in person — all support is through phone, email, or chat.
The account has no monthly fees, no minimum balance requirement, and no limit on how many times you can withdraw money. This makes it straightforward if you want a straightforward savings account. However, if you need a checking account, debit card, or in-person banking, you would need to open a separate Capital One checking account or use a different bank.
The interest rate is higher than most traditional banks offer, but it is not locked in — it changes as the Federal Reserve changes interest rates. Before opening, check Capital One's current rate and compare it to other online banks to see if it matches what you are looking for.
Frequently Asked Questions
Can I open a Capital One 360 account if I do not have a Social Security number?
No. Capital One requires a Social Security number to open any account. If you have an Individual Taxpayer Identification Number (ITIN) instead, you would need to contact Capital One directly to ask whether they can work with you, but standard accounts require an SSN.
What if my identity verification fails?
Capital One will ask you to upload a photo of your government-issued ID. Take a clear photo of both the front and back of your driver's license or passport and upload it through their website. If there are still issues, you can call Capital One's customer service line to complete verification by phone.
How long does it take to transfer money from another bank?
External transfers typically take one to three business days, depending on your other bank and the method you use. Direct deposits follow your employer's normal schedule. You can check the status of any transfer in your Capital One account under "Recent Transfers."
Can I have multiple Capital One 360 savings accounts?
Yes. You can open more than one savings account if you want to organize money for different purposes. Each account has its own number and earns interest separately, though they all use the same login.
What is the interest rate, and will it change?
Capital One's current rate varies and changes over time. Check their website for the current rate before opening. The rate is not locked in — it will change as the Federal Reserve adjusts interest rates, so your earnings will go up or down accordingly.
