What you need to do to connect your bank account
Open Cash App, tap the profile icon in the top left corner, then select Linked Bank Accounts. Tap the plus sign to add a new account. Cash App will ask for your bank's routing number and your account number — both appear on a check or in your bank's online portal. Enter those details, then confirm the small deposits (usually two amounts under $1 each) that your bank sends to Cash App within one to two business days. Once you confirm those amounts in the app, your account is linked.
The whole process takes five to ten minutes of active work, but the waiting part — for your bank to send those verification deposits — can take up to two business days. You cannot send or receive money through that account until the deposits arrive and you confirm them.
Key Takeaways
- You need your bank's routing number and your account number, both found on a check or in your bank's online banking portal.
- Cash App sends two small test deposits to your bank account, and you must confirm the amounts in the app to complete the link.
- The verification deposits usually arrive within one to two business days, but weekends and holidays can extend that timeline.
- Once linked, you can send money to other Cash App users, receive direct deposits, and withdraw cash to that account.
- Cash App stores your bank details encrypted, but you should never share your login credentials or account numbers with anyone claiming to help you.
Where to find your routing and account numbers
The easiest place is a blank check from your checkbook. The routing number is the first set of nine digits on the bottom left. Your account number follows immediately after. If you do not have checks, log into your bank's website or mobile app — most banks display both numbers in the account details or settings section, often labeled "Account Information" or "Routing Number."
Do not call your bank's customer service line to ask for these numbers. They are not secret — they appear on every check you write — and you can find them yourself in seconds. Asking a bank employee to read them to you over the phone creates an unnecessary record and slows you down.
What happens during the verification step
After you enter your routing and account numbers, Cash App initiates a microdeposit verification. Your bank processes this like any other deposit: Cash App sends two amounts (usually between 1 and 99 cents each) to your account. These deposits show up in your bank's transaction history and take the same time as any ACH transfer — typically one to two business days, but sometimes three if your bank processes slowly or if the transfer lands on a weekend.
Once the deposits appear in your bank account, return to Cash App and enter the two amounts you see. Cash App confirms the match, and your account is now linked. If you enter the amounts wrong, you can try again, but repeated failures may lock you out temporarily.
Some banks show pending deposits before they fully clear. If you see the deposits pending but not yet posted, wait until they post before trying to confirm in Cash App — entering amounts for pending deposits will fail.
Linking multiple bank accounts to the same Cash App
You can link up to four bank accounts to a single Cash App profile. Repeat the process for each account: go to Linked Bank Accounts, tap the plus sign, enter the routing and account numbers, wait for the verification deposits, and confirm them. Each account goes through the same two-day verification window.
When you send or receive money, Cash App lets you choose which linked account to use. Your default account is the first one you linked, but you can change it in settings. If you remove a linked account, any pending transfers to that account will fail, so do not unlink an account while a transfer is in progress.
Why verification takes time and what can go wrong
The two-day wait exists because Cash App uses the ACH network, the same system banks use for direct deposits and bill payments. ACH transfers are not instant — they batch process overnight and clear the next business day. Weekends, holidays, and bank processing delays can add another day.
Verification fails most often when you enter the wrong routing number. Each bank has one routing number, but some large banks have multiple routing numbers for different regions or account types. If your first attempt fails, check your bank's website to confirm you have the correct routing number for your specific branch or account type.
If you enter the account number wrong, the deposits may go to the wrong account entirely. Cash App cannot retrieve them, and you will need to contact the bank that received them. To avoid this, copy and paste your account number directly from your bank's website rather than typing it by hand.
Security and what not to do when linking
Cash App encrypts your bank details and does not store your login credentials. You only enter your routing and account number — never your online banking password, PIN, or Social Security number. If anyone claiming to help you link an account asks for your password or login information, that is a scam.
Do not use a shared bank account or someone else's account to link to your Cash App. Cash App's terms prohibit this, and disputes over who owns the money can freeze both accounts. If you want to share money with a family member, use Cash App's transfer feature instead of linking a joint account.
After linking, review your bank's transaction history regularly. Legitimate Cash App transfers show up as ACH debits or credits from "Square Cash" or similar. If you see transfers you did not authorize, contact your bank immediately — they can reverse unauthorized ACH transfers within a set window, usually 60 days.
Removing a linked bank account
Open Cash App, tap the profile icon, select Linked Bank Accounts, then swipe left on the account you want to remove (or tap and hold on Android). Confirm the removal. The account is unlinked immediately, but any transfers already in progress to that account will fail and your money will return to your Cash App balance within one to three business days.
If you are removing an account because you suspect fraud, also change your Cash App password and enable two-factor authentication. Go to Settings, tap Security, and turn on two-factor verification using your phone number or email.
Frequently Asked Questions
How long does it really take to link a bank account?
The active steps take about five to ten minutes. The verification deposits usually arrive within one to two business days, but can take up to three if your bank processes slowly or if the transfer lands over a weekend. You cannot use the account until you confirm those deposits.
Can I link a savings account instead of a checking account?
Yes. Cash App works with both checking and savings accounts as long as you have the correct routing and account number. Some banks use the same routing number for both; others use different ones. Check your bank's website to confirm which routing number applies to your savings account.
What if the verification deposits never show up?
Wait three business days from when you entered your information. If they still have not arrived, log into your bank's website and search your transaction history for deposits from "Square" or "Cash App." If you find them, enter those amounts in Cash App. If you do not find them, the routing or account number was wrong — try again with the correct numbers from your bank's website.
Can I link a bank account from another country?
Cash App only works with U.S. bank accounts. If your bank account is outside the United States, you cannot link it directly. Some users have had success linking accounts through a U.S. bank that offers international services, but this is not officially supported.
What happens if I link the wrong account by mistake?
The verification deposits will go to that account, and you will see them in that bank's transaction history. You can unlink the wrong account and link the correct one instead. The test deposits are yours to keep — the bank that received them will not reverse them automatically.
