You can open an online savings account in 15 minutes to an hour, usually without leaving your home

Online banks let you open a savings account through their website or mobile app. You'll need a government ID, your Social Security number, and a way to fund the account—usually a debit card, existing bank account, or wire transfer. Most online banks have no minimum deposit requirement, though some ask for $25 or $100 to start. The whole process happens on your computer or phone, and your account is typically ready to use the same day or within one business day.

The main difference from a branch bank is that you handle everything remotely. You can't walk into a physical location, but you also don't have to. Online banks tend to offer higher interest rates on savings because they have lower overhead costs, and many charge no monthly fees.

Key Takeaways

  • You need a government-issued ID, Social Security number, and a funding method (debit card or linked bank account) to open an online savings account.
  • The process takes 15 minutes to an hour and happens entirely on your computer or phone, with your account usually ready the same day.
  • Online banks typically offer higher interest rates and lower or no monthly fees compared to traditional branch banks.
  • You'll receive a routing number and account number immediately, which you can use to set up direct deposit or transfers right away.
  • FDIC insurance protects your money up to $250,000 per account holder at most online banks, the same as at branch banks.

What you need before you start

Gather these items before you visit the bank's website or app. You'll need a government-issued photo ID—a driver's license, passport, or state ID card. Have your Social Security number ready. The bank will verify your identity using this information and may run a soft credit check (which doesn't affect your credit score).

You also need a way to fund the account. Most online banks accept a debit card from another bank, or you can link a checking account and transfer money from there. Some banks also accept wire transfers, though that's less common for opening an account. A few banks let you mail in a check, but that takes longer.

Have your phone or computer nearby. Some banks text you a verification code during signup, or ask you to take a photo of your ID. Make sure you're in a quiet place where you can focus—the process moves quickly, and you don't want to miss a step.

The five-step signup process

Start on the bank's website or download their mobile app. Look for a button that says "Open an Account" or "Sign Up"—it's usually on the homepage. Click it and choose "Savings Account" from the account type menu.

Enter your personal information: full name, date of birth, address, phone number, and email. Then provide your Social Security number. The bank will ask whether you're a U.S. citizen and resident. Answer honestly—non-residents and non-citizens may not be able to open accounts at all banks, though some do offer accounts to visa holders.

Next, verify your identity. Most banks ask you to photograph your ID using your phone camera or upload a file from your computer. Some use a video call where you show your ID to a representative. A few banks use instant verification through a third-party service. This step usually takes 2 to 5 minutes.

Then fund the account. Enter your debit card number or link your existing bank account. If you link a bank account, the bank may send two small deposits (usually under $1 each) to that account, and you'll need to confirm the amounts to prove you own it. This verification can take 1 to 3 business days, but your savings account is usually open and usable before that happens.

Finally, set your account preferences. Choose a PIN or password, decide whether you want paperless statements, and review the account terms. You're done. Your account number and routing number appear on screen immediately, and you can start using them right away.

How long it actually takes to be ready to use

Your account is usually open and ready for deposits the same day you sign up. You'll see your account number and routing number on screen before you finish the signup process. If you funded the account with a debit card, money typically arrives within 1 to 3 business days. If you linked a bank account, the transfer takes 1 to 5 business days depending on your bank.

Some banks let you start using the account before the funding arrives—you can set up direct deposit or transfers from another account immediately, even if your opening deposit hasn't cleared yet. Other banks require the opening deposit to clear first. Check the bank's website or call their customer service line to confirm.

If you need to verify your linked bank account using the two-deposit method, that verification takes 1 to 3 business days. During that time, your savings account is still open and working—the verification just confirms you own the other account.

Which online banks have the fewest restrictions

Most major online banks (including Marcus, Ally, Capital One 360, and Discover) have no minimum deposit requirement and no monthly maintenance fees. They all require a Social Security number and government ID. Some require you to be at least 18 years old; a few allow minors with a parent or guardian.

A few online banks have restrictions on who can open an account. Some don't serve customers in certain states, usually due to state banking regulations. Some require a minimum deposit of $25 to $100. A small number require a linked checking account at their bank before you can open savings. Check the bank's website under "Requirements" or "Who Can Open an Account" before you start the signup process.

If you have a history of banking problems—overdrafts, closed accounts, or fraud—some banks may deny your application. You can still try other banks; different banks use different criteria. If you're denied, the bank will tell you why and may suggest alternatives.

How your money is protected

Your money in an online savings account is protected by FDIC insurance (Federal Deposit Insurance Corporation), the same as money in a branch bank. FDIC insurance covers up to $250,000 per account holder per bank. If the bank fails, the FDIC pays you back.

Make sure the bank you choose is FDIC-insured. You can check on the FDIC website by searching for the bank's name. Nearly all major online banks are FDIC-insured, but it's worth confirming before you open an account.

Your account is also protected by the bank's security measures. Online banks use encryption to protect your login information and transactions. You protect your account by using a strong password and not sharing your login details. If someone accesses your account without permission, contact the bank immediately—federal law limits your liability for unauthorized transfers.

What to do if your application is denied

If an online bank denies your application, they'll send you a letter or email explaining why. Common reasons include a negative banking history (too many overdrafts or closed accounts), a fraud flag, or not meeting the bank's age or residency requirements.

You can try a different bank. Each bank has different criteria, and being denied by one doesn't mean you'll be denied by all. Some banks specialize in customers with banking problems or limited credit history. You can also call the bank that denied you and ask if there's anything you can do to reapply later.

If the denial was due to an error in your credit report or identity verification, you can dispute it. Ask the bank which company they used to verify your information, then contact that company directly to correct the error. Once it's fixed, you can reapply.

Frequently Asked Questions

Can I open an online savings account if I don't have a Social Security number?

Most online banks require a Social Security number. If you're a non-citizen, some banks will open accounts using an ITIN (Individual Taxpayer Identification Number) instead. Call the bank before you start the signup process to confirm they accept ITINs.

Do I need to have a checking account at the same bank to open a savings account?

No. You can open a savings account at an online bank without having a checking account there. You can fund it with a debit card from any bank or by linking a checking account from a different bank.

What if I can't verify my identity online because I don't have a smartphone?

Some banks let you upload a photo of your ID from a computer instead of taking a photo with your phone. Others use a video call where you show your ID to a representative on your computer. Call the bank's customer service line and ask what options are available for your situation.

Can I open an online savings account if I'm under 18?

Some online banks allow minors to open accounts with a parent or guardian as a co-owner. Others require you to be 18. Check the bank's website or call customer service to ask about their age policy before you start.

How do I deposit cash into an online savings account?

Most online banks don't accept cash deposits because they have no physical branches. You can deposit cash at your current bank, then transfer the money to your online savings account. Some online banks partner with retail locations (like CVS or Walmart) where you can deposit cash for a fee, though this is less common.
