What happens when you add a bank account to Coinbase

When you add a bank account to Coinbase, you're giving the platform permission to move money between your bank and your Coinbase wallet. Coinbase uses this connection to pull dollars from your bank when you want to buy cryptocurrency, and to send dollars back to your bank when you sell. The connection itself doesn't move money — you initiate each transfer separately.

Coinbase verifies your bank account by sending two small deposits (usually under $1 each) to your account within one to two business days. You then confirm the exact amounts in the Coinbase app to prove you control the account. This verification step protects both you and Coinbase by confirming the account is actually yours.

Once verified, your bank account stays linked until you remove it. You can have multiple bank accounts connected at once, and you can choose which one to use each time you transfer money.

Key Takeaways

  • Coinbase verifies your bank account by sending two small test deposits that you must confirm in the app within 30 days.
  • You need your bank's routing number and your account number to add the account — information you can find on a check or in your bank's online portal.
  • The verification process takes one to two business days for the test deposits to arrive, then a few minutes for you to confirm them.
  • Once verified, transfers from your bank to Coinbase take one to five business days depending on your bank and the transfer amount.

Steps to add a bank account in the Coinbase app

Open the Coinbase app and tap the menu icon (three horizontal lines) in the bottom right corner. Tap Settings, then tap Payment methods. Tap the plus icon to add a new payment method, then select Bank account.

You'll see two options: Connect with Plaid or Enter account details manually. Plaid is faster — it connects to your bank's login system and pulls your account information automatically. If you choose Plaid, enter your bank name, then your online banking username and password. Coinbase does not store these credentials; Plaid handles the login securely and returns only your account details to Coinbase.

If you enter details manually, you'll need your bank's routing number and your account number. Your routing number is a nine-digit code specific to your bank's location. Your account number is the number assigned to your specific account. Both appear on the bottom left of any check you have from that account. If you don't have a check, log into your bank's website or app — most banks display both numbers in the account details section.

After entering your account information, Coinbase will ask for your full name and address to match your bank's records. This must match exactly as it appears on your bank account. Tap Continue when you're done.

Confirming the test deposits

Within one to two business days, Coinbase will send two small deposits to your bank account. The amounts are random and typically between $0.01 and $0.99 each. Check your bank account online or in your bank's app for these deposits — they'll appear as transfers from Coinbase.

Once you see both deposits, return to the Coinbase app. Go back to Settings > Payment methods and find the bank account you just added. It will show a status like "Pending verification" or "Awaiting confirmation." Tap on it and enter the two deposit amounts in the fields provided. The amounts must be exact — if one deposit was $0.47 and the other was $0.82, enter them in that order.

Tap Verify or Confirm (the button name varies by app version). Coinbase will check the amounts against what it sent. If they match, your account is verified when ready and you can begin transferring money. You have 30 days to confirm the deposits before they expire and you'll need to start the process over.

Adding a bank account on the Coinbase website

Log into your Coinbase account at coinbase.com. Click your profile icon in the top right corner and select Settings. Click Payment methods on the left sidebar. Click Add a payment method and select Bank account.

You'll see the same two options as the app: connect via Plaid or enter details manually. The process is identical — Plaid is faster if your bank is supported, and manual entry requires your routing number and account number. Enter your information and click Continue.

The verification step works the same way on the website. Coinbase sends two test deposits within one to two business days. Once they arrive in your bank account, return to Coinbase, find your bank account under Payment methods, and enter the two deposit amounts to confirm.

What to do if test deposits don't arrive

If you don't see the test deposits after three business days, first check that you entered your account number correctly. Log back into Coinbase, go to your bank account in Payment methods, and verify the account number matches what's in your bank's system. A single digit wrong will send the deposits to the wrong account.

If the account number is correct, contact your bank's customer service. Some banks flag small transfers from unfamiliar sources as suspicious and hold them. Ask your bank to check for pending or blocked transfers from Coinbase. If your bank found them, ask them to release the transfers. Once they clear, you can confirm them in Coinbase.

If your bank has no record of the transfers after five business days, remove the bank account from Coinbase and try adding it again. Click the three dots next to your bank account under Payment methods, select Remove, and start the process over. Coinbase will send new test deposits with a new verification code.

Limits on transfers from your bank account

Coinbase sets daily and weekly limits on how much you can transfer from your bank account. These limits depend on your account age, verification level, and payment history. New accounts typically start with lower limits — often $500 to $1,000 per day — and limits increase as you complete more transfers without issues.

Your bank may also set its own limits on transfers to Coinbase. Check your bank's website or call customer service to confirm the maximum transfer amount and frequency your bank allows. Some banks limit ACH transfers (the standard way Coinbase pulls money) to a certain number per month or a maximum dollar amount.

If you hit a limit, you'll see an error message when you try to transfer. Wait until the limit resets (usually the next calendar day for daily limits) or contact Coinbase support to request a limit increase if you've been a customer for several months.

Removing a bank account from Coinbase

To remove a bank account, open the Coinbase app and go to Settings > Payment methods. Find the bank account you want to remove and tap the three dots next to it. Tap Remove and confirm. On the website, click the three dots next to the account and select Remove.

Removing a bank account does not affect any transfers that are already in progress. If you initiated a transfer and then removed the account before it completed, the transfer will still go through. You can add the same bank account back at any time — you'll need to verify it again with the test deposits.

Frequently Asked Questions

Can I use a savings account instead of a checking account?

Yes. Coinbase accepts both checking and savings accounts as long as they're connected to the ACH network, which nearly all U.S. bank accounts are. Enter your savings account number and routing number the same way you would for a checking account.

What if I don't have checks and can't find my routing number?

Log into your bank's website or mobile app and look for account details or account information. Most banks display the routing number and account number there. You can also call your bank's customer service line — they can provide both numbers over the phone.

How long does a transfer from my bank to Coinbase take?

Most transfers take one to five business days. The exact timing depends on your bank and the amount. Smaller transfers sometimes clear faster. Weekends and bank holidays add extra time — a transfer initiated on Friday may not arrive until Tuesday.

Can I transfer money from Coinbase back to my bank account?

Yes. Once your bank account is verified, you can withdraw cryptocurrency to cash and send it to your bank. Go to your wallet, select the asset you want to sell, choose your verified bank account as the destination, and confirm. The cash withdrawal takes the same one to five business days as a deposit.

What happens if I enter the wrong test deposit amounts?

Coinbase will show an error and ask you to try again. You have 30 days total to enter the correct amounts. If you can't remember them, check your bank account statement — the deposits will be listed there with the exact amounts.
