Bank of America's California routing number depends on which branch processes your transfer
Bank of America does not use a single routing number for all California customers. The routing number you need depends on where your account is held and how the transfer is being sent. For most wire transfers initiated by Bank of America customers in California, the routing number is 121000248. However, if you are receiving a wire transfer into a Bank of America account in California, the receiving routing number may differ based on the specific branch or processing center handling the deposit.
The routing number 121000248 is Bank of America's primary routing number for California and is used for ACH transfers, wire transfers, and direct deposits. This is the number you provide to employers, other banks, or individuals sending you money. If you are unsure whether this is the correct number for your specific account, you can confirm it by logging into your Bank of America online account, calling their customer service line, or visiting a local branch.

Where to find your routing number on Bank of America statements and online
Your Bank of America routing number appears on the bottom left of every check you receive with your account. The routing number is the first set of nine digits, followed by your account number and the check number. If you do not have checks or prefer not to look them up manually, you can find your routing number by logging into your Bank of America online account or mobile app and navigating to your account details or transfer settings.
Bank of America's customer service team can also provide your routing number over the phone. Call the number on the back of your debit card or visit a local branch with your ID. Having your account number ready will speed up the process. If you are setting up a wire transfer through Bank of America's website or app, the routing number is often pre-filled automatically based on your account type and location.
What happens when you use the wrong routing number
If you provide an incorrect routing number when sending a wire transfer, the transfer will either be rejected outright or sent to the wrong financial institution. Bank of America's system checks the routing number against a national database before processing. If the number does not match any bank or is invalid, the transfer fails and the money returns to your account within one to three business days.
If the routing number belongs to a real bank but is not your Bank of America account's routing number, the transfer may be accepted by that bank initially but then rejected when the receiving bank realizes the account does not exist there. This rejection process takes longer — sometimes five to ten business days — and you may incur fees from both banks. Always verify the routing number before initiating any wire transfer.
Differences between Bank of America routing numbers and account numbers
Your routing number and account number are two separate pieces of information. The routing number identifies which bank or branch processes your account — in this case, Bank of America in California. The account number identifies your specific account within that bank. Both are required to send or receive wire transfers, and both appear on your checks.
When someone sends you a wire transfer, they need both your routing number (121000248 for most California Bank of America accounts) and your full account number. Providing only one or the other will not work. The routing number tells the sending bank where to send the money; the account number tells Bank of America which customer account to deposit it into.
Wire transfer timing and processing with Bank of America
Wire transfers sent through Bank of America typically process the same business day if initiated before the bank's cutoff time, which is usually 2:00 p.m. Pacific Time on weekdays. Transfers initiated after the cutoff or on weekends and holidays process the next business day. The receiving bank may take an additional one to two business days to make the funds available, depending on their own processing times.
International wire transfers take longer — usually three to five business days — because they pass through multiple banks and currency conversion systems. Bank of America charges fees for outgoing wire transfers, typically between $15 and $30 depending on whether the transfer is domestic or international. Incoming wire transfers are usually free, though some account types may have different fee structures.
Confirming your routing number before sending money
Before you send any wire transfer, take 30 seconds to confirm you have the correct routing number. Log into your Bank of America account online, check a recent statement or check, or call customer service. Mistakes at this stage are easy to catch and cost nothing. Mistakes caught after the transfer is sent can cost time and money.
If you are receiving a wire transfer from someone else, provide them with your routing number (121000248 for California) and your full account number in writing. Ask them to confirm both numbers back to you before they initiate the transfer. This simple step prevents most routing number errors.
