Bank of America's ACH routing number is 021000021, used for electronic transfers between bank accounts

When you set up a direct deposit, pay a bill electronically, or move money between banks, the receiving bank needs to know where to send it. The ACH routing number is the nine-digit code that tells the automated clearing house system which bank holds the account. For Bank of America, that number is 021000021.

This number works the same way whether you're receiving a paycheck, sending money to another person's account, or setting up automatic bill payments. It's not secret—it's printed on the bottom left of Bank of America checks and appears in your online banking settings. The number is the same for all Bank of America customers nationwide, regardless of which branch you use or what state you live in.

Where to find your Bank of America ACH routing number

The easiest place to locate the number is on a check. Look at the bottom left corner—the first nine digits are the routing number. If you don't have a checkbook handy, log into your Bank of America online banking account and go to the account details or account information section. The routing number is listed there alongside your account number.

You can also call Bank of America customer service at 1-800-432-1000 and ask for the ACH routing number. A representative will confirm it's 021000021 and can answer questions about how to use it for your specific transfer.

When you need the ACH routing number

Direct deposit is the most common reason you'll provide this number. Your employer or a government agency (like Social Security or the IRS) needs it to deposit paychecks or tax refunds directly into your Bank of America account. You'll give them the routing number along with your account number.

You also need it when setting up automatic bill payments from your Bank of America account. Utilities, insurance companies, loan servicers, and other creditors ask for the routing number so they can pull payments from your account on the schedule you choose. If you're transferring money from another bank to Bank of America, the sending bank will ask for this number to know where to send the funds.

How ACH transfers work with the routing number

When you provide the routing number and account number, you're giving the automated clearing house (ACH) network the address of your account. The ACH is a system that processes millions of electronic transfers daily. It's not when ready—the transfer goes through a batch process, which is why ACH transfers typically take one to three business days.

The routing number tells the ACH which Federal Reserve bank handles Bank of America's accounts, and from there the money is routed to the specific branch and account number you provided. If the routing number is wrong, the transfer will be rejected or sent to the wrong account, which is why it's important to double-check before submitting.

Difference between ACH routing number and wire transfer routing number

Bank of America has different routing numbers for different types of transfers. The ACH routing number (021000021) is for electronic transfers that take a few business days. If you're doing a wire transfer—which is faster but more expensive—you may need a different routing number depending on which Bank of America location is handling the transfer.

For most people, the ACH routing number is what you need. Wire transfers are less common and usually only used for large, time-sensitive transactions. If someone asks you for a wire routing number, contact Bank of America directly to confirm which number applies to your situation.

What to do if a transfer fails or takes longer than expected

If you've provided the correct routing number and account number but the transfer hasn't arrived after three business days, contact Bank of America. Have the confirmation number from the transfer ready—it's usually provided when you initiate the payment. The bank can trace the transfer and determine whether it's still in process or if something went wrong.

If money was sent to the wrong account because of an incorrect routing number, the receiving bank may be able to reverse it, but this isn't may provide. That's why it's worth taking 30 seconds to verify the number before you submit any transfer, especially for large amounts.
