What you need to do to connect Cash App to your bank
To link Cash App to your bank account, open the app, tap the bank icon at the bottom of the screen, select "Add a Bank Account," enter your routing and account numbers, and confirm the connection. Cash App will deposit two small test amounts (usually under $1 each) to your bank account within one to two business days. You then return to the app and enter those amounts to verify the account is yours.
The entire process takes about five minutes to set up, but the verification step can take up to three business days depending on your bank's processing speed. Once verified, you can transfer money between Cash App and your bank account instantly during business hours, or within one business day on weekends and holidays.
Key Takeaways
- Cash App asks for your routing number and account number, which you can find on a check, your bank's website, or by calling your bank's customer service line.
- The verification step requires you to check your bank account for two small deposits and re-enter those amounts in Cash App to confirm you own the account.
- Transfers from Cash App to your bank account are free and usually arrive within minutes during business hours, or by the next business day otherwise.
- You can link multiple bank accounts to a single Cash App account, but you can only set one as your default destination for transfers.
Where to find your routing and account numbers
Your routing number is a nine-digit code that identifies your specific bank branch. Your account number is unique to your account at that bank. Both appear on the bottom left of any check you have from that account—the routing number comes first, followed by your account number, then your check number.
If you do not have checks, log into your bank's website or mobile app and look for account details, account information, or settings. Most banks display both numbers there. You can also call your bank's customer service number (usually on the back of your debit card) and ask them to read you both numbers over the phone.
The verification step and why it matters
After you enter your routing and account numbers, Cash App sends two small test deposits to your bank account. These are real money—usually between 1 and 99 cents each. Your bank will process them like any other deposit, which means they show up in your account within one to two business days depending on your bank's speed.
Once you see those deposits in your bank account, return to Cash App and tap the bank icon again. Select the account you linked and enter the exact amounts of both deposits. Cash App verifies the amounts match what it sent, confirming you control that bank account. This step prevents someone from linking a bank account that does not belong to them.
If your bank is slow to process deposits, this step can take up to three business days. If you do not see the deposits after three business days, contact your bank to confirm they arrived, or try linking a different account.
What happens after your account is verified
Once verified, you can send money from Cash App to your bank account at any time. Transfers are free and usually arrive within minutes if you request them during your bank's business hours (typically Monday through Friday, 9 a.m. to 5 p.m. in your time zone). Transfers requested after hours or on weekends usually arrive by the next business day.
You can also receive money from other Cash App users directly into your linked bank account. When someone sends you money, you choose whether it goes to your Cash App balance or directly to your bank. Transfers to your bank account are free and follow the same timing as transfers you initiate yourself.
Your linked bank account does not automatically pull money from your bank to fund Cash App transactions. Cash App maintains a separate balance that you load with money from your bank when you choose to. This means you control exactly when money moves between the two accounts.
Linking multiple bank accounts and setting a default
You can add more than one bank account to your Cash App profile. This is useful if you have accounts at different banks or want to keep business and personal money separate. To add another account, tap the bank icon, select "Add a Bank Account," and repeat the verification process with the new account's routing and account numbers.
Only one account can be your default destination for transfers. When you request money to go to your bank, it goes to whichever account you have set as default unless you change it before confirming the transfer. To change your default, tap the bank icon, find the account you want to use, and select it as your primary destination.
What to do if verification fails or takes too long
If Cash App does not receive the test deposits after three business days, the verification will time out and you will need to try again. This usually means your bank is processing deposits slowly, or the routing number you entered was incorrect. Double-check the routing number against your check or your bank's website and try linking the account again.
If you entered the wrong deposit amounts when verifying, Cash App will reject them and ask you to try again. You have multiple attempts to enter the correct amounts. If you cannot find the deposits in your bank account after three business days, contact your bank's customer service to confirm they arrived, then return to Cash App and enter the amounts you see.
If your bank account is flagged as high-risk or if Cash App suspects fraud, the app may refuse to link the account or may delay verification. Contact Cash App's support through the app (tap your profile icon, then "Cash Support") and explain the situation. They can sometimes override the block or tell you what information they need to proceed.
Security and fraud protection when linking accounts
Cash App uses encryption to protect your routing and account numbers during the linking process. This means the numbers are scrambled so that only Cash App can read them. However, once linked, your account is only as secure as your Cash App password and any two-factor authentication you have enabled.
Enable two-factor authentication by tapping your profile icon, selecting "Security," and turning on "Security Key" or "Two-Factor Authentication." This requires anyone trying to access your account—including you on a new device—to enter a code sent to your phone. If someone gains access to your Cash App password, they cannot transfer money from your linked bank account without this second code.
If your Cash App account is hacked or you notice unauthorized transfers, contact Cash App support immediately through the app. They can freeze your account and investigate the transfers. Transfers to your bank account are usually reversible within a few hours if you report them quickly, but transfers that have already arrived at your bank may require your bank to reverse them, which can take longer.
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 accepts both as long as you have the routing number and account number. Transfers to a savings account follow the same timing as transfers to checking—usually instant during business hours, or by the next business day otherwise.
What if I enter the wrong routing number?
If you enter an incorrect routing number, the test deposits will go to the wrong bank or will be rejected. After three business days with no deposits, Cash App will time out the verification. You can then try again with the correct routing number. Check your routing number against a check or your bank's website before re-entering it.
Do I have to verify with the test deposits or is there another way?
The test deposit method is the only way Cash App verifies bank accounts. There is no alternative verification process. The deposits are real money that you keep—they are not fees or charges. Once you confirm the amounts, the account is fully linked and you can transfer money freely.
Can someone else link my bank account to their Cash App?
No. To link your bank account, they would need your routing number, account number, and access to the test deposits in your bank account. Even if they had the first two, they would fail verification because they cannot see the deposits you receive. The verification step prevents unauthorized linking.
What if my bank does not show the test deposits?
Contact your bank and ask if the deposits arrived. Some banks delay showing small deposits for a day or two, or they may appear under a different name. If your bank confirms the deposits never arrived, the routing number may be wrong. Try linking the account again with a corrected routing number, or contact Cash App support for help.
