Yes, you can link your bank account to Cash App, and it takes about five minutes
Cash App lets you connect a checking or savings account so money can move between your bank and the app. You'll need your account and routing number, which you can find on a check, your bank's website, or by calling the bank. Cash App uses this connection to pull money into the app when you send it, and to push money back out when you receive it. The link itself is free — Cash App does not charge you to add a bank account.
The connection is not instant. When you first link an account, Cash App may hold it for verification for up to 24 hours. After that, transfers between your bank and Cash App usually land within one to three business days, though some banks are faster. If you're sending money to another person through Cash App, the speed depends on whether they're receiving it as a Cash App balance (instant) or to their own bank account (one to three days).
Key Takeaways
- You need your account number and routing number from your bank to link; these appear on checks or your bank's website.
- Cash App verifies new bank links within 24 hours, and transfers between your bank and the app take one to three business days.
- Linking a bank account is free, but Cash App charges a fee if you send money to another person's bank account (1.5% of the amount, with a minimum of 25 cents).
- You can link multiple bank accounts to one Cash App, but only one can be your default for receiving money.
- If a transfer fails or takes longer than expected, check that your account number and routing number are correct, and confirm your bank hasn't blocked the transaction.
What information Cash App needs from your bank
Cash App asks for your account number and routing number. Your account number is unique to you at that bank; your routing number identifies the bank itself. Both appear on the bottom left of any check you have. If you don't have checks, log into your bank's website or app — most banks display both numbers in the account details section. You can also call your bank's customer service line and ask for your routing number; they'll give it to you over the phone.
Do not use someone else's account number or routing number. Cash App will reject mismatched information, and if you somehow succeed in linking the wrong account, transfers will fail and your bank may flag the activity as fraud. The account must be in your name or a name you're authorized to use.
Steps to link your bank account in the app
Open Cash App and tap the profile icon in the top right corner. Select "Linked Bank Accounts" or "Bank Accounts" (the exact wording varies by app version). Tap "Add Bank Account" or the plus icon. Enter your account number and routing number in the fields provided. Cash App will ask you to confirm the account holder's name — make sure it matches what your bank has on file.
After you submit, Cash App sends a verification request to your bank. This usually completes within 24 hours, though it can take longer if your bank is slow to respond or if you submit the request on a weekend or holiday. You'll see a notification in the app when verification is complete. Until then, you can't transfer money using that account, but the link is saved and waiting.
How long transfers take once your account is linked
Money moving from your bank into Cash App takes one to three business days. Money moving from Cash App back to your bank also takes one to three business days. The exact timing depends on your bank — some process transfers faster than others, and some have cutoff times (for example, transfers submitted after 5 p.m. may not start until the next business day).
If you're sending money to another Cash App user and they accept it as a Cash App balance (not a bank transfer), that lands instantly. If they choose to move it to their bank account, that's when the one to three day window applies. Weekend and holiday transfers usually don't start moving until the next business day.
Fees for transfers and sending money
Linking your bank account to Cash App is free. Transferring money between your bank and Cash App is free. However, Cash App charges a fee if you send money to another person's bank account directly through the app — that fee is 1.5% of the amount you send, with a minimum of 25 cents. If you send $100 to someone's bank account, you'll pay $1.50. If you send $10, you'll pay 25 cents.
There is no fee if you send money to another Cash App user (they receive it in their Cash App balance). There is also no fee if you transfer money from your Cash App balance back to your own linked bank account. The 1.5% fee only applies when you're sending to someone else's bank account.
What to do if your bank account won't link or verification fails
If Cash App rejects your account number or routing number, double-check both against your check or your bank's website. A single wrong digit will cause the link to fail. Make sure you're entering numbers only — no letters, spaces, or dashes. If the numbers are correct and Cash App still rejects them, your bank may not support Cash App transfers, or your account may have restrictions that prevent third-party links.
If verification takes longer than 24 hours, check your email for messages from Cash App or your bank. Some banks send a confirmation email asking you to approve the link before it goes through. If you don't see anything, wait another 24 hours — verification can be slow over weekends. If it's been more than 48 hours, contact your bank's customer service and ask whether they've received a verification request from Cash App. They can tell you if the request is stuck or if your bank is blocking it.
Linking multiple bank accounts and changing your default
You can link more than one bank account to Cash App. This is useful if you have accounts at different banks or if you want to keep a separate account for Cash App transfers. To add another account, follow the same steps: tap your profile, select "Linked Bank Accounts," and tap "Add Bank Account." Each account will go through the same 24-hour verification process.
Only one account can be your default for receiving money. When someone sends you money through Cash App, it goes to your default account unless you change it before the transfer lands. To change your default, go to "Linked Bank Accounts," find the account you want to use, and select it as default. You can switch your default as often as you want, but the change takes effect immediately for new transfers.
Security and fraud protection when your bank account is linked
Cash App uses encryption to protect your account number and routing number — the same technology banks use. Your bank account information is not stored on your phone; it's stored on Cash App's servers. However, your Cash App account itself is only as secure as your password and phone number. If someone gains access to your Cash App account, they can see your linked bank accounts and potentially transfer money out.
To protect yourself, use a strong password (not your birthday or a simple number sequence), enable two-factor authentication if Cash App offers it, and keep your phone's operating system and the Cash App itself updated. If you notice an unauthorized transfer, contact Cash App support immediately and also call your bank. Your bank can reverse fraudulent transfers and may be able to block Cash App from accessing your account while you sort it out. Cash App's fraud protection covers some unauthorized activity, but your bank's protections are usually stronger.
Frequently Asked Questions
Can I link a savings account, or does it have to be checking?
You can link either a checking or savings account. Cash App does not care which type it is. However, some banks restrict how often you can transfer money out of a savings account (federal rules allow up to six per month), so if you plan to move money frequently, a checking account may be more practical.
What happens if I unlink my bank account?
If you unlink a bank account, Cash App stops using it for new transfers. Any transfers already in progress will complete. You can link the same account again later by entering the account number and routing number again — you'll go through verification a second time. Unlinking does not affect your Cash App balance or any money already in the app.
Do I need a Social Security number to link my bank account?
Cash App may ask for your Social Security number as part of account verification, especially if you're linking for the first time or if you're sending large amounts of money. This is normal and required by federal law for money transfer services. Your SSN is encrypted and not shared with your bank.
Can I link someone else's bank account to my Cash App?
No. Cash App requires the account holder's name to match the name on your Cash App account. If you try to link an account in someone else's name, verification will fail. If you need to receive money from someone, they can send it to your Cash App username or phone number — you don't need their bank account linked to your app.
Why is my transfer taking longer than three days?
Check that your account number and routing number are correct — a typo will cause the transfer to fail or get stuck. Confirm with your bank that they haven't blocked the transaction (some banks flag Cash App transfers as suspicious). Also check whether you submitted the transfer after your bank's cutoff time; if so, it may not start processing until the next business day. If it's been more than five business days, contact Cash App support with your transfer ID.
